+ * DOC: overview
+ *
+ * DM provides another layer of IRQ management on top of what the base driver
+ * already provides. This is something that could be cleaned up, and is a
+ * future TODO item.
+ *
+ * The base driver provides IRQ source registration with DRM, handler
+ * registration into the base driver's IRQ table, and a handler callback
+ * amdgpu_irq_handler(), with which DRM calls on interrupts. This generic
+ * handler looks up the IRQ table, and calls the respective
+ * &amdgpu_irq_src_funcs.process hookups.
+ *
+ * What DM provides on top are two IRQ tables specifically for top-half and
+ * bottom-half IRQ handling, with the bottom-half implementing workqueues:
+ *
+ * - &amdgpu_display_manager.irq_handler_list_high_tab
+ * - &amdgpu_display_manager.irq_handler_list_low_tab
+ *
+ * They override the base driver's IRQ table, and the effect can be seen
+ * in the hooks that DM provides for &amdgpu_irq_src_funcs.process. They
+ * are all set to the DM generic handler amdgpu_dm_irq_handler(), which looks up
+ * DM's IRQ tables. However, in order for base driver to recognize this hook, DM
+ * still needs to register the IRQ with the base driver. See
+ * dce110_register_irq_handlers() and dcn10_register_irq_handlers().
+ *
+ * To expose DC's hardware interrupt toggle to the base driver, DM implements
+ * &amdgpu_irq_src_funcs.set hooks. Base driver calls it through
+ * amdgpu_irq_update() to enable or disable the interrupt.

- * suspend. One way to solve this is to have a hardware state read-out

- *
- * The simpler solution is to just reset the software state to everything off,
- * which is easiest to do by calling drm_mode_config_reset(). To facilitate this
- * the atomic helpers provide default reset implementations for all hooks.
- *
- * On the upside the precise state tracking of atomic simplifies system suspend
- * and resume a lot. For drivers using drm_mode_config_reset() a complete recipe
- * is implemented in drm_atomic_helper_suspend() and drm_atomic_helper_resume().
- * For other drivers the building blocks are split out, see the documentation

+/**
+ * DOC: atomic state reset and initialization
+ *
+ * Both the drm core and the atomic helpers assume that there is always the full
+ * and correct atomic software state for all connectors, CRTCs and planes
+ * available. Which is a bit a problem on driver load and also after system
+ * suspend. One way to solve this is to have a hardware state read-out
+ * infrastructure which reconstructs the full software state (e.g. the i915
+ * driver).
+ *
+ * The simpler solution is to just reset the software state to everything off,
+ * which is easiest to do by calling drm_mode_config_reset(). To facilitate this
+ * the atomic helpers provide default reset implementations for all hooks.
+ *
+ * On the upside the precise state tracking of atomic simplifies system suspend
+ * and resume a lot. For drivers using drm_mode_config_reset() a complete recipe
+ * is implemented in drm_atomic_helper_suspend() and drm_atomic_helper_resume().
+ * For other drivers the building blocks are split out, see the documentation
+ * for these functions.

+ * Semantic changes:
+ * * Using the wrong device for i2c, framebuffer_alloc and
+ * prime import.
+ * Visual changes:
+ * * Helpers such as DRM_DEV_ERROR, dev_info, drm_printer,
+ * will print the wrong information.
+ *
+ * We could address the latter issues, by introducing

+ * v4l2_phys_addr_validate() - validate a physical address from an EDID
+ *
+ * @phys_addr: the physical address to validate
+ * @parent: if not %NULL, then this is filled with the parents PA.
+ * @port: if not %NULL, then this is filled with the input port.
+ *
+ * This validates a physical address as read from an EDID. If the
+ * PA is invalid (such as 1.0.1.0 since '0' is only allowed at the end),
+ * then it will return -EINVAL.
+ *
+ * The parent PA is passed into %parent and the input port is passed into
+ * %port. For example:
+ *
+ * PA = 0.0.0.0: has parent 0.0.0.0 and input port 0.
+ *
+ * PA = 1.0.0.0: has parent 0.0.0.0 and input port 1.
+ *
+ * PA = 3.2.0.0: has parent 3.0.0.0 and input port 2.
+ *
+ * PA = f.f.f.f: has parent f.f.f.f and input port 0.
+ *
+ * Return: 0 if the PA is valid, -EINVAL if not.

- With this driver you will be able to use UBI and create a ubifs on the

-
- These devices ship with the Mys/Sandisk SAFTL formatting, for which
- there is currently no mtd parser, so you may want to use command line
- partitioning to segregate write-protected blocks. On the Treo680, the
- first five erase blocks (256KiB each) are write-protected, followed
- by the block containing the saftl partition table. This is probably

* Copyright (C) 2017 Marvell

*
+ *
+ * This NAND controller driver handles two versions of the hardware,
+ * one is called NFCv1 and is available on PXA SoCs and the other is
+ * called NFCv2 and is available on Armada SoCs.
+ *
+ * The main visible difference is that NFCv1 only has Hamming ECC
+ * capabilities, while NFCv2 also embeds a BCH ECC engine. Also, DMA
+ * is not used with NFCv2.
+ *
+ * The ECC layouts are depicted in details in Marvell AN-379, but here
+ * is a brief description.
+ *
+ * When using Hamming, the data is split in 512B chunks (either 1, 2
+ * or 4) and each chunk will have its own ECC "digest" of 6B at the
+ * beginning of the OOB area and eventually the remaining free OOB
+ * bytes (also called "spare" bytes in the driver). This engine
+ * corrects up to 1 bit per chunk and detects reliably an error if
+ * there are at most 2 bitflips. Here is the page layout used by the
+ * controller when Hamming is chosen:
+ *
+ * +-------------------------------------------------------------+
+ * | Data 1 | ... | Data N | ECC 1 | ... | ECCN | Free OOB bytes |
+ * +-------------------------------------------------------------+
+ *
+ * When using the BCH engine, there are N identical (data + free OOB +
+ * ECC) sections and potentially an extra one to deal with
+ * configurations where the chosen (data + free OOB + ECC) sizes do
+ * not align with the page (data + OOB) size. ECC bytes are always
+ * 30B per ECC chunk. Here is the page layout used by the controller
+ * when BCH is chosen:
+ *
+ * +-----------------------------------------
+ * | Data 1 | Free OOB bytes 1 | ECC 1 | ...
+ * +-----------------------------------------
+ *
+ * -------------------------------------------
+ * ... | Data N | Free OOB bytes N | ECC N |
+ * -------------------------------------------
+ *
+ * --------------------------------------------+
+ * Last Data | Last Free OOB bytes | Last ECC |
+ * --------------------------------------------+
+ *
+ * In both cases, the layout seen by the user is always: all data
+ * first, then all free OOB bytes and finally all ECC bytes. With BCH,
+ * ECC bytes are 30B long and are padded with 0xFF to align on 32
+ * bytes.
+ *
+ * The controller has certain limitations that are handled by the
+ * driver:
+ * - It can only read 2k at a time. To overcome this limitation, the
+ * driver issues data cycles on the bus, without issuing new
+ * CMD + ADDR cycles. The Marvell term is "naked" operations.
+ * - The ECC strength in BCH mode cannot be tuned. It is fixed 16
+ * bits. What can be tuned is the ECC block size as long as it
+ * stays between 512B and 2kiB. It's usually chosen based on the
+ * chip ECC requirements. For instance, using 2kiB ECC chunks
+ * provides 4b/512B correctability.
+ * - The controller will always treat data bytes, free OOB bytes
+ * and ECC bytes in that order, no matter what the real layout is
+ * (which is usually all data then all OOB bytes). The
+ * marvell_nfc_layouts array below contains the currently
+ * supported layouts.
+ * - Because of these weird layouts, the Bad Block Markers can be
+ * located in data section. In this case, the NAND_BBT_NO_OOB_BBM
+ * option must be set to prevent scanning/writing bad block
+ * markers.

+ * port based on predetermined configurations. FW logging via the Rx CQ can be
+ * enabled/disabled for individual PF's. However, FW logging via the UART can
+ * only be enabled/disabled for all PFs on the same device.
+ *
+ * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
+ * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
+ * before initializing the device.
+ *
+ * When re/configuring FW logging, callers need to update the "cfg" elements of
+ * the hw->fw_log.evnts array with the desired logging event configurations for
+ * modules of interest. When disabling FW logging completely, the callers can
+ * just pass false in the "enable" parameter. On completion, the function will
+ * update the "cur" element of the hw->fw_log.evnts array with the resulting
+ * logging event configurations of the modules that are being re/configured. FW
+ * logging modules that are not part of a reconfiguration operation retain their
+ * previous states.
+ *
+ * Before resetting the device, it is recommended that the driver disables FW
+ * logging before shutting down the control queue. When disabling FW logging
+ * ("enable" = false), the latest configurations of FW logging events stored in
+ * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
+ * a device reset.
+ *
+ * When enabling FW logging to emit log messages via the Rx CQ during the
+ * device's initialization phase, a mechanism alternative to interrupt handlers
+ * needs to be used to extract FW log messages from the Rx CQ periodically and
+ * to prevent the Rx CQ from being full and stalling other types of control
+ * messages from FW to SW. Interrupts are typically disabled during the device's

+ * address through ret_reg(), instead of pushing it to the stack right
+ * here, are the following:
+ * - It looks cleaner.
+ * - If the called function is called multiple time, we get a lower
+ * program size.
+ * - We save two no-op instructions that should be added just before
+ * the emit_br() when stack depth is not null otherwise.
+ * - If we ever find a register to hold the return address during whole
+ * execution of the callee, we will not have to push the return
+ * address to the stack for leaf functions.

+Contributions are solicited in particular to remedy the following issues:
+
+cpcihp:
+
+* There are no implementations of the ->hardware_test, ->get_power and
+ ->set_power callbacks in struct cpci_hp_controller_ops. Why were they
+ introduced? Can they be removed from the struct?
+
+cpqphp:
+
+* The driver spawns a kthread cpqhp_event_thread() which is woken by the
+ hardirq handler cpqhp_ctrl_intr(). Convert this to threaded IRQ handling.
+ The kthread is also woken from the timer pushbutton_helper_thread(),
+ convert it to call irq_wake_thread(). Use pciehp as a template.
+
+* A large portion of cpqphp_ctrl.c and cpqphp_pci.c concerns resource
+ management. Doesn't this duplicate functionality in the core?
+
+ibmphp:
+
+* Implementations of hotplug_slot_ops callbacks such as get_adapter_present()
+ in ibmphp_core.c create a copy of the struct slot on the stack, then perform
+ the actual operation on that copy. Determine if this overhead is necessary,
+ delete it if not. The functions also perform a NULL pointer check on the
+ struct hotplug_slot, this seems superfluous.
+
+* Several functions access the pci_slot member in struct hotplug_slot even
+ though pci_hotplug.h declares it private. See get_max_bus_speed() for an
+ example. Either the pci_slot member should no longer be declared private
+ or ibmphp should store a pointer to its bus in struct slot. Probably the
+ former.
+
+* The functions get_max_adapter_speed() and get_bus_name() are commented out.
+ Can they be deleted? There are also forward declarations at the top of
+ ibmphp_core.c as well as pointers in ibmphp_hotplug_slot_ops, likewise
+ commented out.
+
+* ibmphp_init_devno() takes a struct slot **, it could instead take a
+ struct slot *.
+
+* The return value of pci_hp_register() is not checked.
+
+* iounmap(io_mem) is called in the error path of ebda_rsrc_controller()
+ and once more in the error path of its caller ibmphp_access_ebda().
+
+* The various slot data structures are difficult to follow and need to be
+ simplified. A lot of functions are too large and too complex, they need
+ to be broken up into smaller, manageable pieces. Negative examples are
+ ebda_rsrc_controller() and configure_bridge().
+
+* A large portion of ibmphp_res.c and ibmphp_pci.c concerns resource
+ management. Doesn't this duplicate functionality in the core?
+
+sgi_hotplug:
+
+* Several functions access the pci_slot member in struct hotplug_slot even
+ though pci_hotplug.h declares it private. See sn_hp_destroy() for an
+ example. Either the pci_slot member should no longer be declared private
+ or sgi_hotplug should store a pointer to it in struct slot. Probably the
+ former.
+
+shpchp:
+
+* There is only a single implementation of struct hpc_ops. Can the struct be
+ removed and its functions invoked directly? This has already been done in
+ pciehp with commit 82a9e79ef132 ("PCI: pciehp: remove hpc_ops"). Clarify
+ if there was a specific reason not to apply the same change to shpchp.
+
+* The ->get_mode1_ECC_cap callback in shpchp_hpc_ops is never invoked.
+ Why was it introduced? Can it be removed?
+
+* The hardirq handler shpc_isr() queues events on a workqueue. It can be
+ simplified by converting it to threaded IRQ handling. Use pciehp as a
+ template.

+ * 88 to 95 is 88 + MDIO1 source for level 2 MDIO function.

+ Universal Flash Storage (UFS) is SCSI transport specification for

+ A UFS controller communicates with a UFS device by exchanging

+ UPIUs can not only be used as a transport layer for the SCSI protocol
+ but are also used by the UFS native command set.
+ This transport driver supports exchanging UFS protocol information units
+ with a UFS device. See also the ufshcd driver, which is a SCSI driver
+ that supports UFS devices.

+ * Some of these have no NI_ prefix as they are useful for non-NI hardware, such

+ * NOTE ABOUT THE CHOICE OF NAMES HERE AND THE CAMELSCRIPT:
+ * The choice to use CamelScript and the exact names below is for
+ * maintainability, clarity, similarity to manufacturer's documentation,
+ * _and_ a mitigation for confusion that has plagued the use of these drivers
+ * for years!
+ *
+ * More detail:
+ * There have been significant confusions over the past many years for users
+ * when trying to understand how to connect to/from signals and terminals on
+ * NI hardware using comedi. The major reason for this is that the actual
+ * register values were exposed and required to be used by users. Several
+ * major reasons exist why this caused major confusion for users:
+ * 1) The register values are _NOT_ in user documentation, but rather in
+ * arcane locations, such as a few register programming manuals that are
+ * increasingly hard to find and the NI MHDDK (comments in in example code).
+ * There is no one place to find the various valid values of the registers.
+ * 2) The register values are _NOT_ completely consistent. There is no way to
+ * gain any sense of intuition of which values, or even enums one should use
+ * for various registers. There was some attempt in prior use of comedi to
+ * name enums such that a user might know which enums should be used for
+ * varying purposes, but the end-user had to gain a knowledge of register
+ * values to correctly wield this approach.
+ * 3) The names for signals and registers found in the various register level
+ * programming manuals and vendor-provided documentation are _not_ even
+ * close to the same names that are in the end-user documentation.
+ *
+ * Similar, albeit less, confusion plagued NI's previous version of their own
+ * drivers. Earlier than 2003, NI greatly simplified the situation for users
+ * by releasing a new API that abstracted the names of signals/terminals to a
+ * common and intuitive set of names.
+ *
+ * The names below mirror the names chosen and well documented by NI. These
+ * names are exposed to the user via the comedilib user library. By keeping
+ * the names below, in spite of the use of CamelScript, maintenance will be
+ * greatly eased and confusion for users _and_ comedi developers will be
+ * greatly reduced.

+ * abstracted NI signal/terminal name.
+ * These values are also used/returned by INSN_DEVICE_CONFIG_TEST_ROUTE,

+Framework for Maintaining Common National Instruments Terminal/Signal names
+
+The contents of this directory are primarily for maintaining and formatting all
+known valid signal routes for various National Instruments devices.
+
+Some background:
+ There have been significant confusions over the past many years for users
+ when trying to understand how to connect to/from signals and terminals on
+ NI hardware using comedi. The major reason for this is that the actual
+ register values were exposed and required to be used by users. Several
+ major reasons exist why this caused major confusion for users:
+
+ 1) The register values are _NOT_ in user documentation, but rather in
+ arcane locations, such as a few register programming manuals that are
+ increasingly hard to find and the NI-MHDDK (comments in in example code).
+ There is no one place to find the various valid values of the registers.
+
+ 2) The register values are _NOT_ completely consistent. There is no way to
+ gain any sense of intuition of which values, or even enums one should use
+ for various registers. There was some attempt in prior use of comedi to
+ name enums such that a user might know which enums should be used for
+ varying purposes, but the end-user had to gain a knowledge of register
+ values to correctly wield this approach.
+
+ 3) The names for signals and registers found in the various register level
+ programming manuals and vendor-provided documentation are _not_ even
+ close to the same names that are in the end-user documentation.
+
+ 4) The sets of routes that are valid are not consistent from device to device.
+ One additional major challenge is that this information does not seem to be
+ obtainable in any programmatic fashion, neither through the proprietary
+ NIDAQmx(-base) c-libraries, nor with register level programming, _nor_
+ through any documentation. In fact, the only consistent source of this
+ information is through the proprietary NI-MAX software, which currently only
+ runs on Windows platforms. A further challenge is that this information
+ cannot be exported from NI-MAX, except by screenshot.
+
+
+
+The content of this directory is part of an effort to greatly simplify the use
+of signal routing capabilities of National Instruments data-acquisition and
+control hardware. In order to facilitate the transfer of register-level
+information _and_ the knowledge of valid routes per device, a few specific
+choices were made:
+
+
+1) The names of the National Instruments signals/terminals that are used in this
+ directory are chosen to be consistent with (a) the NI's user level
+ documentation, (b) NI's user-level code, (c) the information as provided by
+ the proprietary NI-MAX software, and (d) the user interface code provided by
+ the user-land comedilib library.
+
+ The impact of this choice implies that one allows the use of CamelScript names
+ in the kernel. In short, the choice to use CamelScript and the exact names
+ below is for maintainability, clarity, similarity to manufacturer's
+ documentation, _and_ a mitigation for confusion that has plagued the use of
+ these drivers for years!
+
+2) The bulk of the real content for this directory is stored in two separate
+ collections (i.e. sub-directories) of tables stored in c source files:
+
+ (a) ni_route_values/ni_[series-label]series.c
+
+ This data represents all the various register values to use for the
+ multiple different signal MUXes for the specific device families.
+
+ The values are all wrapped in one of three macros to help document and
+ track which values have been implemented and tested.
+ These macros are:
+ V(<value>) : register value is valid, tested, and implemented
+ I(<value>) : register value is implemented but needs testing
+ U(<value>) : register value is not implemented
+
+ The actual function of these macros will depend on whether the code is
+ compiled in the kernel or whether it is compiled into the conversion
+ tools. For the conversion tools, it can be used to indicate the status
+ of the register value. For the kernel, V() and I() both perform the
+ same function and prepare data to be used; U() zeroes out the value to
+ ensure that it cannot be used.
+
+ *** It would be a great help for users to test these values such that
+ these files can be correctly marked/documented ***
+
+ (b) ni_device_routes/[board-name].c
+
+ This data represents the known set of valid signal routes that are
+ possible for each specific board. Although the family defines the
+ register values to use for a particular signal MUX, not all possible
+ signals are actually available on each board.
+
+ In order for a particular board to take advantage of the effort to
+ simplify/clarify signal routing on NI devices, a corresponding
+ [board-name].c file must be created. This file should reflect the known
+ valid _direct_ routing capabilities of the board.
+
+ As noted above, the only known consistent source of information for
+ valid device routes comes from the proprietary National Instruments
+ Windows software, NI-MAX. Also, as noted above, this information can
+ only be visually conveyed from NI-MAX to other media. To make this
+ easier, the naming conventions used in the [board-name].c file are
+ similar to the naming conventions as presented by NI-MAX.
+
+
+3) Two other files aggregate the above data to integrate it into comedi:
+ ni_route_values.c
+ ni_device_routes.c
+
+ When adding a new [board-name].c file, be sure to also add in the line in
+ ni_device_routes.c to include this information into comedi.
+
+
+4) Several tools have been included to convert from/to the c file formats.
+ These tools are best used/demonstrated via the included Makefile targets:
+ (a) `make csv-files`
+ Creates new csv-files using content of c-files of existing
+ ni_routing/* content. New csv files are placed in csv
+ sub-directory.
+
+ As noted above, the only consistent source of information of valid
+ device routes comes from the proprietary National Instruments Windows
+ software, NI-MAX. Also, as noted above, this information can only be
+ visually conveyed from NI-MAX to other media. This make target creates
+ spreadsheet representations of the routing data. The choice of using a
+ spreadsheet (ala CSV) to copy this information allows for easy direct
+ visual comparison to the NI-MAX "Valid Routes" tables.
+
+ Furthermore, the register-level information is much easier to identify and
+ correct when entire families of NI devices are shown side by side in table
+ format. This is made easy by using a file-storage format that can be
+ loaded into a spreadsheet application.
+
+ Finally, .csv content is very easy to edit and read using a variety of
+ tools, including spreadsheets or various other scripting languages. In
+ fact, the tools provided here enable quick conversion of the
+ spreadsheet-like .csv format to c-files that follow the kernel coding
+ conventions.
+
+
+ (b) `make c-files`
+ Creates new c-files using content of csv sub-directory. These
+ new c-files can be compared to the active content in the
+ ni_routing directory.
+ (c) `make csv-blank`
+ Create a new blank csv file. This is useful for establishing a
+ new data table for either a device family (less likely) or a
+ specific board of an existing device family (more likely).
+ (d) `make clean`
+ Remove all generated files/directories.
+ (e) `make everything`
+ Build all csv-files, then all new c-files.
+
+
+
+
+In summary, similar confusion about signal routing configuration, albeit less,
+plagued NI's previous version of their own proprietary drivers. Earlier than
+2003, NI greatly simplified the situation for users by releasing a new API that
+abstracted the names of signals/terminals to a common and intuitive set of
+names. In addition, this new API provided a much more common interface to use
+for most of NI hardware.
+
+Comedi already provides such a common interface for data-acquisition and control
+hardware. This effort complements comedi's abstraction layers by further
+abstracting much more of the use cases for NI hardware, but allowing users _and_
+developers to directly refer to NI documentation (user-level, register-level,
+and the register-level examples of the NI-MHDDK).
+
+
+
+--------------------------------------------------------------------------------
+Various naming conventions and relations:
+--------------------------------------------------------------------------------
+These are various notes that help to relate the naming conventions used in the
+NI-STC with those naming conventions used here.
+--------------------------------------------------------------------------------
+
+ Signal sources for most signals-destinations are given a specific naming
+ convention, although the register values are not consistent. This next table
+ shows the mapping between the names used in comedi for NI and those names
+ typically used within the NI-STC documentation.

+ * According to DAQ-STC:
+ * RTSI Board Interface--Configured as an input, each bidirectional
+ * RTSI_BRD pin can drive any of the seven RTSI_TRIGGER pins.
+ * RTSI_BRD<0..1> can also be driven by AI STOP and RTSI_BRD<2..3>
+ * can also be driven by the AI START and SCAN_IN_PROG signals.
+ * These pins provide a mechanism for additional board-level signals
+ * to be sent on or received from the RTSI bus.
+ * Couple of comments:
+ * - Neither the DAQ-STC nor the MHDDK is clear on what the direction
+ * of the RTSI_BRD pins actually means. There does not appear to be
+ * any clear indication on what "output" would mean, since the point
+ * of the RTSI_BRD lines is to always drive one of the
+ * RTSI_TRIGGER<0..6> lines.
+ * - The DAQ-STC also indicates that the NI_RTSI_BRD lines can be
+ * driven by any of the RTSI_TRIGGER<0..6> lines.
+ * But, looking at valid device routes, as visually imported from
+ * NI-MAX, there appears to be only one family (so far) that has the
+ * ability to route a signal from one TRIGGER_LINE to another
+ * TRIGGER_LINE: the 653x family of DIO devices.
+ *
+ * For m-series, the bit layout of this register is
+ * (docs: mhddk/nimseries/ChipObjects/tMSeries.{h,ipp}):
+ * bits 0:3 -- NI_RTSI_BRD(0) source selection
+ * bits 4:7 -- NI_RTSI_BRD(1) source selection
+ * bits 8:11 -- NI_RTSI_BRD(2) source selection
+ * bits 12:15 -- NI_RTSI_BRD(3) source selection
+ * Note: The m-series does not have any option to change direction of
+ * NI_RTSI_BRD muxes. Furthermore, there are no register values that
+ * indicate the ability to have TRIGGER_LINES driving the output of
+ * the NI_RTSI_BRD muxes.

-* Add a DPAA2 MAC kernel driver in order to allow PHY management; currently
- the DPMAC objects and their link to DPNIs are handled by MC internally
- and all PHYs are seen as fixed-link
-* add more debug support: decide how to expose detailed debug statistics,
- add ingress error queue support
-* MC firmware uprev; the DPAA2 objects used by the Ethernet driver need to
- be kept in sync with binary interface changes in MC
-* refine README file
-* cleanup
-
-NOTE: None of the above is must-have before getting the DPAA2 Ethernet driver
-out of staging. The main requirement for that is to have the drivers it
-depends on, fsl-mc bus and DPIO driver, moved to drivers/bus and drivers/soc
-respectively.

-DPAA2 Ethernet driver
-===============================
-
-:Copyright: |copy| 2017-2018 NXP
-
-This file provides documentation for the Freescale DPAA2 Ethernet driver.
-
-Supported Platforms
-===================
-This driver provides networking support for Freescale DPAA2 SoCs, e.g.
-LS2080A, LS2088A, LS1088A.
-
-
-Architecture Overview
-=====================
-Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
-representing network interfaces; instead, several separate hardware resources
-concur to provide the networking functionality:
-
-- network interfaces
-- queues, channels
-- buffer pools
-- MAC/PHY
-
-All hardware resources are allocated and configured through the Management
-Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
-and exposes ABIs through which they can be configured and controlled. A few
-hardware resources, like queues, do not have a corresponding MC object and
-are treated as internal resources of other objects.
-
-For a more detailed description of the DPAA2 architecture and its object
-abstractions see *Documentation/networking/dpaa2/overview.rst*.
-
-Each Linux net device is built on top of a Datapath Network Interface (DPNI)
-object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
-(DPCONs).
-

- | DPBP | | DPNI | | DPCON |
- ------ ------ -------
-
-The DPNIs are network interfaces without a direct one-on-one mapping to PHYs.
-DPBPs represent hardware buffer pools. Packet I/O is performed in the context
-of DPCON objects, using DPIO portals for managing and communicating with the
-hardware resources.

- ---------------------- | -------------
- =======================
- Channel
-
-Datapath I/O (DPIO) portals provide enqueue and dequeue services, data
-availability notifications and buffer pool management. DPIOs are shared between
-all DPAA2 objects (and implicitly all DPAA2 kernel drivers) that work with data
-frames, but must be affine to the CPUs for the purpose of traffic distribution.
-
-Frames are transmitted and received through hardware frame queues, which can be
-grouped in channels for the purpose of hardware scheduling. The Ethernet driver
-enqueues TX frames on egress queues and after transmission is complete a TX
-confirmation frame is sent back to the CPU.
-
-When frames are available on ingress queues, a data availability notification
-is sent to the CPU; notifications are raised per channel, so even if multiple
-queues in the same channel have available frames, only one notification is sent.
-After a channel fires a notification, is must be explicitly rearmed.
-
-Each network interface can have multiple Rx, Tx and confirmation queues affined
-to CPUs, and one channel (DPCON) for each CPU that services at least one queue.
-DPCONs are used to distribute ingress traffic to different CPUs via the cores'
-affine DPIOs.
-
-The role of hardware buffer pools is storage of ingress frame data. Each network
-interface has a privately owned buffer pool which it seeds with kernel allocated
-buffers.
-
-
-DPNIs are decoupled from PHYs; a DPNI can be connected to a PHY through a DPMAC
-object or to another DPNI through an internal link, but the connection is
-managed by MC and completely transparent to the Ethernet driver.

-
-Creating a Network Interface
-============================
-A net device is created for each DPNI object probed on the MC bus. Each DPNI has
-a number of properties which determine the network interface configuration
-options and associated hardware resources.
-
-DPNI objects (and the other DPAA2 objects needed for a network interface) can be
-added to a container on the MC bus in one of two ways: statically, through a
-Datapath Layout Binary file (DPL) that is parsed by MC at boot time; or created
-dynamically at runtime, via the DPAA2 objects APIs.
-
-
-Features & Offloads
-===================
-Hardware checksum offloading is supported for TCP and UDP over IPv4/6 frames.
-The checksum offloads can be independently configured on RX and TX through
-ethtool.
-
-Hardware offload of unicast and multicast MAC filtering is supported on the
-ingress path and permanently enabled.
-
-Scatter-gather frames are supported on both RX and TX paths. On TX, SG support
-is configurable via ethtool; on RX it is always enabled.
-
-The DPAA2 hardware can process jumbo Ethernet frames of up to 10K bytes.
-
-The Ethernet driver defines a static flow hashing scheme that distributes
-traffic based on a 5-tuple key: src IP, dst IP, IP proto, L4 src port,
-L4 dst port. No user configuration is supported for now.
-
-Hardware specific statistics for the network interface as well as some
-non-standard driver stats can be consulted through ethtool -S option.

While this approach allows support for arbitrary OF graphs, there

- If a device has mixed-use ports such as video plus audio, the
- endpoints from the audio ports are followed to devices that must
- bind to V4L2 subdevice drivers, and not for example, to an ALSA
- driver or a non-V4L2 media driver. If the device were bound to
- such a driver, imx-media would never get an async completion
- notification because the device fwnode was added to the async
- list, but the driver does not interface with the V4L2 async
- framework.

+ *
+ * In this driver we use IDs 0 and 1. Counter ID 1 is used as watchdog counter,
+ * while counter ID 0 is used to implement pinging the watchdog: counter ID 1 is
+ * set to restart counting from initial value on counter ID 0 end count event.
+ * Pinging is done by forcing immediate end count event on counter ID 0.
+ * If only one counter was used, pinging would have to be implemented by
+ * disabling and enabling the counter, leaving the system in a vulnerable state
+ * for a (really) short period of time.
+ *
+ * Counters ID 2 and 3 are enabled by default even before U-Boot loads,
+ * therefore this driver does not provide a way to use them, eg. by setting a

- * 1. BIOS
- * For P4SBx:
- * BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
- * For P4DPx:
- * BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
- * This setting enables or disables Watchdog function. When enabled, the
- * default watchdog timer is set to be 5 minutes (about 4m35s). It is
- * enough to load and run the OS. The application (service or driver) has
- * to take over the control once OS is running up and before watchdog
- * expires.
- *
- * 2. JUMPER
- * For P4SBx: JP39
- * For P4DPx: JP37
- * This jumper is used for safety. Closed is enabled. This jumper
- * prevents user enables watchdog in BIOS by accident.
- *
- * To enable Watch Dog function, both BIOS and JUMPER must be enabled.
- *
- * The documentation lists motherboards P4SBx and P4DPx series as of
- * 20-March-2002. However, this code works flawlessly with much newer
- * motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
- *
- * The original iTCO driver as written does not actually reset the
- * watchdog timer on these machines, as a result they reboot after five
- * minutes.
- *
- * NOTE: You may leave the Watchdog function disabled in the SuperMicro
- * BIOS to avoid a "boot-race"... This driver will enable watchdog
- * functionality even if it's disabled in the BIOS once the /dev/watchdog
- * file is opened.
