+ * Implementation of the SCU based Power Domains
+ *
+ * NOTE: a better implementation suggested by Ulf Hansson is using a
+ * single global power domain and implement the ->attach|detach_dev()
+ * callback for the genpd and use the regular of_genpd_add_provider_simple().
+ * From within the ->attach_dev(), we could get the OF node for
+ * the device that is being attached and then parse the power-domain
+ * cell containing the "resource id" and store that in the per device
+ * struct generic_pm_domain_data (we have void pointer there for
+ * storing these kind of things).
+ *
+ * Additionally, we need to implement the ->stop() and ->start()
+ * callbacks of genpd, which is where you "power on/off" devices,
+ * rather than using the above ->power_on|off() callbacks.
+ *
+ * However, there're two known issues:
+ * 1. The ->attach_dev() of power domain infrastructure still does
+ *    not support multi domains case as the struct device *dev passed
+ *    in is a virtual PD device, it does not help for parsing the real
+ *    device resource id from device tree, so it's unware of which
+ *    real sub power domain of device should be attached.
+ *
+ *    The framework needs some proper extension to support multi power
+ *    domain cases.
+ *
+ * 2. It also breaks most of current drivers as the driver probe sequence
+ *    behavior changed if removing ->power_on|off() callback and use
+ *    ->start() and ->stop() instead. genpd_dev_pm_attach will only power
+ *    up the domain and attach device, but will not call .start() which
+ *    relies on device runtime pm. That means the device power is still
+ *    not up before running driver probe function. For SCU enabled
+ *    platforms, all device drivers accessing registers/clock without power
+ *    domain enabled will trigger a HW access error. That means we need fix
+ *    most drivers probe sequence with proper runtime pm.
+ *
+ * In summary, we need fix above two issue before being able to switch to
+ * the "single global power domain" way.

+This is a place for planning the ongoing long-term work in the GPIO
+subsystem.
+
+
+GPIO descriptors
+
+Starting with commit 79a9becda894 the GPIO subsystem embarked on a journey
+to move away from the global GPIO numberspace and toward a decriptor-based
+approach. This means that GPIO consumers, drivers and machine descriptions
+ideally have no use or idea of the global GPIO numberspace that has/was
+used in the inception of the GPIO subsystem.
+
+Work items:
+
+- Convert all GPIO device drivers to only #include <linux/gpio/driver.h>
+
+- Convert all consumer drivers to only #include <linux/gpio/consumer.h>
+
+- Convert all machine descriptors in "boardfiles" to only
+  #include <linux/gpio/machine.h>, the other option being to convert it
+  to a machine description such as device tree, ACPI or fwnode that
+  implicitly does not use global GPIO numbers.
+
+- When this work is complete (will require some of the items in the
+  following ongoing work as well) we can delete the old global
+  numberspace accessors from <linux/gpio.h> and eventually delete
+  <linux/gpio.h> altogether.
+
+
+Get rid of <linux/of_gpio.h>
+
+This header and helpers appeared at one point when there was no proper
+driver infrastructure for doing simpler MMIO GPIO devices and there was
+no core support for parsing device tree GPIOs from the core library with
+the [devm_]gpiod_get() calls we have today that will implicitly go into
+the device tree back-end.
+
+Work items:
+
+- Get rid of struct of_mm_gpio_chip altogether: use the generic  MMIO
+  GPIO for all current users (see below). Delete struct of_mm_gpio_chip,
+  to_of_mm_gpio_chip(), of_mm_gpiochip_add_data(), of_mm_gpiochip_add()
+  of_mm_gpiochip_remove() from the kernel.
+
+- Change all consumer drivers that #include <linux/of_gpio.h> to
+  #include <linux/gpio/consumer.h> and stop doing custom parsing of the
+  GPIO lines from the device tree. This can be tricky and often ivolves
+  changing boardfiles, etc.
+
+- Pull semantics for legacy device tree (OF) GPIO lookups into
+  gpiolib-of.c: in some cases subsystems are doing custom flags and
+  lookups for polarity inversion, open drain and what not. As we now
+  handle this with generic OF bindings, pull all legacy handling into
+  gpiolib so the library API becomes narrow and deep and handle all
+  legacy bindings internally. (See e.g. commits 6953c57ab172,
+  6a537d48461d etc)
+
+- Delete <linux/of_gpio.h> when all the above is complete and everything
+  uses <linux/gpio/consumer.h> or <linux/gpio/driver.h> instead.
+
+
+Collect drivers
+
+Collect GPIO drivers from arch/* and other places that should be placed
+in drivers/gpio/gpio-*. Augment platforms to create platform devices or
+similar and probe a proper driver in the gpiolib subsystem.
+
+In some cases it makes sense to create a GPIO chip from the local driver
+for a few GPIOs. Those should stay where they are.
+
+
+Generic MMIO GPIO
+
+The GPIO drivers can utilize the generic MMIO helper library in many
+cases, and the helper library should be as helpful as possible for MMIO
+drivers. (drivers/gpio/gpio-mmio.c)
+
+Work items:
+
+- Look over and identify any remaining easily converted drivers and
+  dry-code conversions to MMIO GPIO for maintainers to test
+
+- Expand the MMIO GPIO or write a new library for port-mapped I/O
+  helpers (x86 inb()/outb()) and convert port-mapped I/O drivers to use
+  this with dry-coding and sending to maintainers to test
+
+
+GPIOLIB irqchip
+
+The GPIOLIB irqchip is a helper irqchip for "simple cases" that should
+try to cover any generic kind of irqchip cascaded from a GPIO.
+
+- Look over and identify any remaining easily converted drivers and
+  dry-code conversions to gpiolib irqchip for maintainers to test
+
+- Support generic hierarchical GPIO interrupts: these are for the
+  non-cascading case where there is one IRQ per GPIO line, there is
+  currently no common infrastructure for this.
+
+
+Increase integration with pin control
+
+There are already ways to use pin control as back-end for GPIO and
+it may make sense to bring these subsystems closer. One reason for
+creating pin control as its own subsystem was that we could avoid any
+use of the global GPIO numbers. Once the above is complete, it may
+make sense to simply join the subsystems into one and make pin
+multiplexing, pin configuration, GPIO, etc selectable options in one
+and the same pin control and GPIO subsystem.

+ * 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.

+/**
+ * DOC: Overview
+ *
+ * DC is the OS-agnostic component of the amdgpu DC driver.
+ *
+ * DC maintains and validates a set of structs representing the state of the
+ * driver and writes that state to AMD hardware
+ *
+ * Main DC HW structs:
+ *
+ * struct dc - The central struct.  One per driver.  Created on driver load,
+ * destroyed on driver unload.
+ *
+ * struct dc_context - One per driver.
+ * Used as a backpointer by most other structs in dc.
+ *
+ * struct dc_link - One per connector (the physical DP, HDMI, miniDP, or eDP
+ * plugpoints).  Created on driver load, destroyed on driver unload.
+ *
+ * struct dc_sink - One per display.  Created on boot or hotplug.
+ * Destroyed on shutdown or hotunplug.  A dc_link can have a local sink
+ * (the display directly attached).  It may also have one or more remote
+ * sinks (in the Multi-Stream Transport case)
+ *
+ * struct resource_pool - One per driver.  Represents the hw blocks not in the
+ * main pipeline.  Not directly accessible by dm.
+ *
+ * Main dc state structs:
+ *
+ * These structs can be created and destroyed as needed.  There is a full set of
+ * these structs in dc->current_state representing the currently programmed state.
+ *
+ * struct dc_state - The global DC state to track global state information,
+ * such as bandwidth values.
+ *
+ * struct dc_stream_state - Represents the hw configuration for the pipeline from
+ * a framebuffer to a display.  Maps one-to-one with dc_sink.
+ *
+ * struct dc_plane_state - Represents a framebuffer.  Each stream has at least one,
+ * and may have more in the Multi-Plane Overlay case.
+ *
+ * struct resource_context - Represents the programmable state of everything in
+ * the resource_pool.  Not directly accessible by dm.
+ *
+ * struct pipe_ctx - A member of struct resource_context.  Represents the
+ * internal hardware pipeline components.  Each dc_plane_state has either
+ * one or two (in the pipe-split case).

 /**
+ * DOC: Variable refresh properties
+ *
+ * Variable refresh rate capable displays can dynamically adjust their
+ * refresh rate by extending the duration of their vertical front porch
+ * until page flip or timeout occurs. This can reduce or remove stuttering
+ * and latency in scenarios where the page flip does not align with the
+ * vblank interval.
+ *
+ * An example scenario would be an application flipping at a constant rate
+ * of 48Hz on a 60Hz display. The page flip will frequently miss the vblank
+ * interval and the same contents will be displayed twice. This can be
+ * observed as stuttering for content with motion.
+ *
+ * If variable refresh rate was active on a display that supported a
+ * variable refresh range from 35Hz to 60Hz no stuttering would be observable
+ * for the example scenario. The minimum supported variable refresh rate of
+ * 35Hz is below the page flip frequency and the vertical front porch can
+ * be extended until the page flip occurs. The vblank interval will be
+ * directly aligned to the page flip rate.
+ *
+ * Not all userspace content is suitable for use with variable refresh rate.
+ * Large and frequent changes in vertical front porch duration may worsen
+ * perceived stuttering for input sensitive applications.
+ *
+ * Panel brightness will also vary with vertical front porch duration. Some
+ * panels may have noticeable differences in brightness between the minimum
+ * vertical front porch duration and the maximum vertical front porch duration.
+ * Large and frequent changes in vertical front porch duration may produce
+ * observable flickering for such panels.
+ *
+ * Userspace control for variable refresh rate is supported via properties
+ * on the &drm_connector and &drm_crtc objects.
+ *
+ * "vrr_capable":
+ *	Optional &drm_connector boolean property that drivers should attach
+ *	with drm_connector_attach_vrr_capable_property() on connectors that
+ *	could support variable refresh rates. Drivers should update the
+ *	property value by calling drm_connector_set_vrr_capable_property().
+ *
+ *	Absence of the property should indicate absence of support.
+ *
+ * "vrr_enabled":
+ *	Default &drm_crtc boolean property that notifies the driver that the
+ *	content on the CRTC is suitable for variable refresh rate presentation.
+ *	The driver will take this property as a hint to enable variable
+ *	refresh rate support if the receiver supports it, ie. if the
+ *	"vrr_capable" property is true on the &drm_connector object. The
+ *	vertical front porch duration will be extended until page-flip or
+ *	timeout when enabled.
+ *
+ *	The minimum vertical front porch duration is defined as the vertical
+ *	front porch duration for the current mode.
+ *
+ *	The maximum vertical front porch duration is greater than or equal to
+ *	the minimum vertical front porch duration. The duration is derived
+ *	from the minimum supported variable refresh rate for the connector.
+ *
+ *	The driver may place further restrictions within these minimum
+ *	and maximum bounds.
+ *
+ *	The semantics for the vertical blank timestamp differ when
+ *	variable refresh rate is active. The vertical blank timestamp
+ *	is defined to be an estimate using the current mode's fixed

+ * DOC: overview
+ *
+ * FB_DAMAGE_CLIPS is an optional plane property which provides a means to
+ * specify a list of damage rectangles on a plane in framebuffer coordinates of
+ * the framebuffer attached to the plane. In current context damage is the area
+ * of plane framebuffer that has changed since last plane update (also called
+ * page-flip), irrespective of whether currently attached framebuffer is same as
+ * framebuffer attached during last plane update or not.
+ *
+ * FB_DAMAGE_CLIPS is a hint to kernel which could be helpful for some drivers
+ * to optimize internally especially for virtual devices where each framebuffer
+ * change needs to be transmitted over network, usb, etc.
+ *
+ * Since FB_DAMAGE_CLIPS is a hint so it is an optional property. User-space can
+ * ignore damage clips property and in that case driver will do a full plane
+ * update. In case damage clips are provided then it is guaranteed that the area
+ * inside damage clips will be updated to plane. For efficiency driver can do
+ * full update or can update more than specified in damage clips. Since driver
+ * is free to read more, user-space must always render the entire visible
+ * framebuffer. Otherwise there can be corruptions. Also, if a user-space
+ * provides damage clips which doesn't encompass the actual damage to
+ * framebuffer (since last plane update) can result in incorrect rendering.
+ *
+ * FB_DAMAGE_CLIPS is a blob property with the layout of blob data is simply an
+ * array of &drm_mode_rect. Unlike plane &drm_plane_state.src coordinates,
+ * damage clips are not in 16.16 fixed point. Similar to plane src in
+ * framebuffer, damage clips cannot be negative. In damage clip, x1/y1 are
+ * inclusive and x2/y2 are exclusive. While kernel does not error for overlapped
+ * damage clips, it is strongly discouraged.
+ *
+ * Drivers that are interested in damage interface for plane should enable
+ * FB_DAMAGE_CLIPS property by calling drm_plane_enable_fb_damage_clips().
+ * Drivers implementing damage can use drm_atomic_helper_damage_iter_init() and
+ * drm_atomic_helper_damage_iter_next() helper iterator function to get damage
+ * rectangles clipped to &drm_plane_state.src.

+		 *
+		 * A few other ideas were considered:
+		 * - Extend the dev_is_pci() check [in drm_set_busid] to
+		 *   consider virtio.
+		 *   Seems like a bigger hack than what we have already.
+		 *
+		 * - Point drm_device::dev to the parent of the virtio_device
+		 *   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
+		 * drm_device::bus_dev, ... which would be used solely for this.

+	  I3C is a serial protocol standardized by the MIPI alliance.
+
+	  It's supposed to be backward compatible with I2C while providing
+	  support for high speed transfers and native interrupt support
+	  without the need for extra pins.
+
+	  The I3C protocol also standardizes the slave device types and is
+	  mainly designed to communicate with sensors.
+
+	  If you want I3C support, you should say Y here and also to the
+	  specific driver for your bus adapter(s) below.
+
+	  This I3C support can also be built as a module.  If so, the module
+	  will be called i3c.

- * D-channel protocol identifiers
- *
- * Attention: Unfortunately the identifiers defined here differ from
- *      the identifiers used in Protocol/1/Common/prot/q931.h .
- *     The only reason for this is that q931.h has not a global
- *     scope and we did not know about the definitions there.
- *     But the definitions here cannot be changed easily because
- *     they are used in setup scripts and programs.
- *     Thus the definitions here have to be mapped if they are
- *     used in the protocol code context !
- *
- * Now the identifiers are defined in the q931lib/constant.h file.
- * Unfortunately this file has also not a global scope.
- * But beginning with PROTTYPE_US any new identifier will get the same
- * value as the corresponding PROT_* definition in q931lib/constant.h !

-   For all systems, that are linked by Kernel Mode Linker this is ONLY one

-   of this adapter (sync request) in order to receive appropriate services:
-   - add new adapter
-   - remove existing adapter
-   - add adapter array notification
-   - remove adapter array notification
-   (read adapter is redundant in this case)
-   INPUT:
-   buffer - pointer to buffer that will receive adapter array
-   length  - length (in bytes) of space in buffer
-   OUTPUT:
-   Adapter array will be written to memory described by 'buffer'
-   If the last adapter seen in the returned adapter array is
-   IDI_DADAPTER or if last adapter in array does have type '0', then
-   it was enougth space in buffer to accommodate all available
-   adapter descriptors
-   *NOTE 1 (debug interface):
-   The IDI adapter of type 'IDI_DIMAINT' does register as 'request'
-   famous 'dprintf' function (of type DI_PRINTF, please look
-   include/debuglib.c and include/debuglib.h) for details.
-   So dprintf is not exported from module debug module directly,
-   instead of this IDI_DIMAINT is registered.
-   Module load order will receive in this case:
-   1. DIDD (this file)
-   2. DIMAINT does load and register 'IDI_DIMAINT', at this step
-   DIDD should be able to get 'dprintf', save it, and
-   register with DIDD by means of 'dprintf' function.
-   3. any other driver is loaded and is able to access adapter array
-   and debug interface
-   This approach does allow to load/unload debug interface on demand,
-   and save memory, it it is necessary.

+ *  - the PLL multiplier output rate should be in the 500-1000MHz range
+ *  - PCLK >= SCLK * 2 in YUV, >= SCLK in Raw or JPEG

+ * In the two latter cases, these constraints are met since our

+ * take this into account. The only varying parts are the PLL
+ * multiplier and the system clock divider, which are shared between
+ * all these clocks so won't cause any issue.

+ *
+ * @rate: The requested bandwidth per lane in bytes per second.
+ *	  'Bandwidth Per Lane' is calculated as:
+ *	  bpl = HTOT * VTOT * FPS * bpp / num_lanes;
+ *
+ * This function use the requested bandwidth to calculate:
+ * - sample_rate = bpl / (bpp / num_lanes);
+ *	         = bpl / (PLL_RDIV * BIT_DIV * PCLK_DIV * MIPI_DIV / num_lanes);
+ *
+ * - mipi_sclk   = bpl / MIPI_DIV / 2; ( / 2 is for CSI-2 DDR)
+ *
+ * with these fixed parameters:
+ *	PLL_RDIV	= 2;
+ *	BIT_DIVIDER	= 2; (MIPI_BIT_MODE == 8 ? 2 : 2,5);
+ *	PCLK_DIV	= 1;
+ *
+ * The MIPI clock generation differs for modes that use the scaler and modes
+ * that do not. In case the scaler is in use, the MIPI_SCLK generates the MIPI
+ * BIT CLk, and thus:
+ *
+ * - mipi_sclk = bpl / MIPI_DIV / 2;
+ *   MIPI_DIV = 1;
+ *
+ * For modes that do not go through the scaler, the MIPI BIT CLOCK is generated
+ * from the pixel clock, and thus:
+ *
+ * - sample_rate = bpl / (bpp / num_lanes);
+ *	         = bpl / (2 * 2 * 1 * MIPI_DIV / num_lanes);
+ *		 = bpl / (4 * MIPI_DIV / num_lanes);
+ * - MIPI_DIV	 = bpp / (4 * num_lanes);
+ *
+ * FIXME: this have been tested with 16bpp and 2 lanes setup only.
+ * MIPI_DIV is fixed to value 2, but it -might- be changed according to the
+ * above formula for setups with 1 lane or image formats with different bpp.
+ *
+ * FIXME: this deviates from the sensor manual documentation which is quite

-	  RedBoot is a ROM monitor and bootloader which deals with multiple

- * side effects like removing some block protections.
- * Secondly, it uses the Read Configuration Register (35h) instruction though

- * resistor is present on the MISO/IO1 line, we might still be able to pass the
- * "read back" test because the QSPI memory doesn't recognize the command,
- * so leaves the MISO/IO1 line state unchanged, hence read_cr() returns 0xFF.

+ * The PMIC has four sets of registers corresponding to four power modes:
+ * Performance, Active, Low-power, Hibernate.
+ *
+ * Registers:
+ * Each regulator has a register for each power mode. To access a register
+ * for a specific regulator and mode BASE_* and OFFSET_* need to be added.
+ *
+ * Operating modes:
+ * In order for the PMIC to transition to operating modes it has to be
+ * controlled via GPIO lines called LPM and HPM.
+ *
+ * The registers are fully configurable such that you can put all regulators in
+ * a low-power state while the PMIC is in Active mode. They are supposed to be
+ * configured at startup and then simply transition to/from a global low-power
+ * state by setting the GPIO lpm pin high/low.
+ *
+ * This driver keeps the PMIC in Active mode, Low-power state is set for the
+ * regulators by enabling/disabling operating mode (FPWM or Auto PFM).
+ *
+ * The PMIC's Low-power and Hibernate modes are used during standby/suspend.
+ * To enter standby/suspend the PMIC will go to Low-power mode. From there, it
+ * will transition to Hibernate when the PWRHLD line is set to low by the MPU.

+ * bcm2835_spi_transfer_prologue() - transfer first few bytes without DMA
+ * @master: SPI master
+ * @tfr: SPI transfer
+ * @bs: BCM2835 SPI controller
+ * @cs: CS register
+ *
+ * A limitation in DMA mode is that the FIFO must be accessed in 4 byte chunks.
+ * Only the final write access is permitted to transmit less than 4 bytes, the
+ * SPI controller deduces its intended size from the DLEN register.
+ *
+ * If a TX or RX sglist contains multiple entries, one per page, and the first
+ * entry starts in the middle of a page, that first entry's length may not be
+ * a multiple of 4.  Subsequent entries are fine because they span an entire
+ * page, hence do have a length that's a multiple of 4.
+ *
+ * This cannot happen with kmalloc'ed buffers (which is what most clients use)
+ * because they are contiguous in physical memory and therefore not split on
+ * page boundaries by spi_map_buf().  But it *can* happen with vmalloc'ed
+ * buffers.
+ *
+ * The DMA engine is incapable of combining sglist entries into a continuous
+ * stream of 4 byte chunks, it treats every entry separately:  A TX entry is
+ * rounded up a to a multiple of 4 bytes by transmitting surplus bytes, an RX
+ * entry is rounded up by throwing away received bytes.
+ *
+ * Overcome this limitation by transferring the first few bytes without DMA:
+ * E.g. if the first TX sglist entry's length is 23 and the first RX's is 42,
+ * write 3 bytes to the TX FIFO but read only 2 bytes from the RX FIFO.
+ * The residue of 1 byte in the RX FIFO is picked up by DMA.  Together with
+ * the rest of the first RX sglist entry it makes up a multiple of 4 bytes.
+ *
+ * Should the RX prologue be larger, say, 3 vis-à-vis a TX prologue of 1,
+ * write 1 + 4 = 5 bytes to the TX FIFO and read 3 bytes from the RX FIFO.
+ * Caution, the additional 4 bytes spill over to the second TX sglist entry
+ * if the length of the first is *exactly* 1.
+ *
+ * At most 6 bytes are written and at most 3 bytes read.  Do we know the
+ * transfer has this many bytes?  Yes, see BCM2835_SPI_DMA_MIN_LENGTH.
+ *
+ * The FIFO is normally accessed with 8-bit width by the CPU and 32-bit width
+ * by the DMA engine.  Toggling the DMA Enable flag in the CS register switches
+ * the width but also garbles the FIFO's contents.  The prologue must therefore
+ * be transmitted in 32-bit width to ensure that the following DMA transfer can
+ * pick up the residue in the RX FIFO in ungarbled form.

+This is a list of things that need to be done to get this driver out of the
+staging directory.
+
+- Request API conversion. Remove of the dual pipeline and associate buffers
+  as well as formats and the binary used to a request. Remove the
+  opportunistic buffer management. (Sakari)
+
+- Using ENABLED and IMMUTABLE link flags for the links where those are
+  relevant. (Sakari)
+
+- Prefix imgu for all public APIs, i.e. change ipu3_v4l2_register() to
+  imgu_v4l2_register(). (Sakari)
+
+- Use V4L2_CTRL_TYPE_MENU for dual-pipe mode control. (Sakari)
+
+- IPU3 driver documentation (Laurent)
+  Add diagram in driver rst to describe output capability.
+  Comments on configuring v4l2 subdevs for CIO2 and ImgU.
+
+- uAPI documentation:
+  Further clarification on some ambiguities such as data type conversion of
+  IEFD CU inputs. (Sakari)
+  Move acronyms to doc-rst file. (Mauro)
+
+- Switch to yavta from v4l2n in driver docs.
+
+- Elaborate the functionality of different selection rectangles in driver
+  documentation. This may require driver changes as well.
+
+- More detailed documentation on calculating BDS, GCD etc. sizes needed.
+
+- Document different operation modes, and which buffer queues are relevant
+  in each mode. To process an image, which queues require a buffer an in
+  which ones is it optional?

+To make the sound module create a sound card and register it with ALSA the
+string "create" needs to be attached to the module parameter section of the
+configuration string. To create a sound card with with two playback devices
+(linked to channel ep01 and ep02) and one capture device (linked to channel
+ep83) the following is written to the add_link file:
 
+        $ echo "mdev0:ep01:sound:most51_playback.6x16" >$(DRV_DIR)/add_link
+        $ echo "mdev0:ep02:sound:most_playback.2x16" >$(DRV_DIR)/add_link
+        $ echo "mdev0:ep83:sound:most_capture.2x16.create" >$(DRV_DIR)/add_link
 
+The link names (most51_playback, most_playback and most_capture) will
+become the names of the PCM devices of the sound card.

+- reg: Base addresses and lengths of the PCIe subsys and root ports.
+- bus-range: Range of bus numbers associated with this controller.
+- #address-cells: Address representation for root ports (must be 3)
+- pinctrl-names : The pin control state names.
+- pinctrl-0: The "default" pinctrl state.
+- #size-cells: Size representation for root ports (must be 2)
+- ranges: Ranges for the PCI memory and I/O regions.
+- #interrupt-cells: Must be 1
+- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties.
+  Please refer to the standard PCI bus binding document for a more detailed
+  explanation.
+- status: either "disabled" or "okay".
+- resets: Must contain an entry for each entry in reset-names.
+  See ../reset/reset.txt for details.
+- reset-names: Must be "pcie0", "pcie1", "pcieN"... based on the number of
+  root ports.
+- clocks: Must contain an entry for each entry in clock-names.
+  See ../clocks/clock-bindings.txt for details.
+- clock-names: Must be "pcie0", "pcie1", "pcieN"... based on the number of
+  root ports.
+
+In addition, the device tree node must have sub-nodes describing each PCIe port
+interface, having the following mandatory properties:
+
+Required properties:
+- reg: Only the first four bytes are used to refer to the correct bus number
+      and device number.
+- #address-cells: Must be 3
+- #size-cells: Must be 2
+- ranges: Sub-ranges distributed from the PCIe controller node. An empty
+  property is sufficient.
+- bus-range: Range of bus numbers associated with this port.

-1) Document the device tree node
-
-The downstream tree(the tree that the driver was imported from) at
-http://www.github.com/raspberrypi/linux uses this node:
-
-audio: audio {
-	compatible = "brcm,bcm2835-audio";
-	brcm,pwm-channels = <8>;

-
-Since the driver requires the use of VCHIQ, it may be useful to have a link
-in the device tree to the VCHIQ driver.
-
-2) Gracefully handle the case where VCHIQ is missing from the device tree or
-it has not been initialized yet.
-
-3) Review error handling and remove duplicate code.
-
-4) Cleanup the logging mechanism.  The driver should probably be using the
-standard kernel logging mechanisms such as dev_info, dev_dbg, and friends.
-
-5) Fix the remaining checkpatch.pl errors and warnings.

 A short top-down description of this driver's architecture (function of
 kthreads, userspace, limitations) could be very helpful for reviewers.
+
+7) Review and comment memory barriers
+
+There is a heavy use of memory barriers in this driver, it would be very
+beneficial to go over all of them and, if correct, comment on their merits.
+Extra points to whomever confidently reviews the remote_event_*() family of
+functions.
+
+8) Get rid of custom function return values
+
+Most functions use a custom set of return values, we should force proper Linux
+error numbers. Special care is needed for VCHIQ_RETRY.
+
+9) Reformat core code with more sane indentations
+
+The code follows the 80 characters limitation yet tends to go 3 or 4 levels of
+indentation deep making it very unpleasant to read. This is specially relevant
+in the character driver ioctl code and in the core thread functions.
+
+10) Reorganize file structure: Move char driver to it's own file and join both
+platform files
+
+The cdev is defined alongside with the platform code in vchiq_arm.c. It would
+be nice to completely decouple it from the actual core code. For instance to be
+able to use bcm2835-audio without having /dev/vchiq created. One could argue
+it's better for security reasons or general cleanliness. It could even be
+interesting to create two different kernel modules, something the likes of
+vchiq-core.ko and vchiq-dev.ko. This would also ease the upstreaming process.
+
+The code in vchiq_bcm2835_arm.c should fit in the generic platform file.
+
+12) Get rid of all the struct typedefs
+
+Most structs are typedefd, it's not encouraged in the kernel.
+
+13) Get rid of all non essential global structures and create a proper per
+device structure
+
+The first thing one generally sees in a probe function is a memory allocation
+for all the device specific data. This structure is then passed all over the
+driver. This is good practice since it makes the driver work regardless of the
+number of devices probed.

+ * dwc3_gadget_start_isoc_quirk - workaround invalid frame number
+ * @dep: isoc endpoint
+ *
+ * This function tests for the correct combination of BIT[15:14] from the 16-bit
+ * microframe number reported by the XferNotReady event for the future frame
+ * number to start the isoc transfer.
+ *
+ * In DWC_usb31 version 1.70a-ea06 and prior, for highspeed and fullspeed
+ * isochronous IN, BIT[15:14] of the 16-bit microframe number reported by the
+ * XferNotReady event are invalid. The driver uses this number to schedule the
+ * isochronous transfer and passes it to the START TRANSFER command. Because
+ * this number is invalid, the command may fail. If BIT[15:14] matches the
+ * internal 16-bit microframe, the START TRANSFER command will pass and the
+ * transfer will start at the scheduled time, if it is off by 1, the command
+ * will still pass, but the transfer will start 2 seconds in the future. For all
+ * other conditions, the START TRANSFER command will fail with bus-expiry.
+ *
+ * In order to workaround this issue, we can test for the correct combination of
+ * BIT[15:14] by sending START TRANSFER commands with different values of
+ * BIT[15:14]: 'b00, 'b01, 'b10, and 'b11. Each combination is 2^14 uframe apart
+ * (or 2 seconds). 4 seconds into the future will result in a bus-expiry status.
+ * As the result, within the 4 possible combinations for BIT[15:14], there will
+ * be 2 successful and 2 failure START COMMAND status. One of the 2 successful
+ * command status will result in a 2-second delay start. The smaller BIT[15:14]
+ * value is the correct combination.
+ *
+ * Since there are only 4 outcomes and the results are ordered, we can simply
+ * test 2 START TRANSFER commands with BIT[15:14] combinations 'b00 and 'b01 to
+ * deduce the smaller successful combination.
+ *
+ * Let test0 = test status for combination 'b00 and test1 = test status for 'b01
+ * of BIT[15:14]. The correct combination is as follow:
+ *
+ * if test0 fails and test1 passes, BIT[15:14] is 'b01
+ * if test0 fails and test1 fails, BIT[15:14] is 'b10
+ * if test0 passes and test1 fails, BIT[15:14] is 'b11
+ * if test0 passes and test1 passes, BIT[15:14] is 'b00

+	  USB Role Switch is a device that can select the USB role - host or
+	  device - for a USB port (connector). In most cases dual-role capable
+	  USB controller will also represent the switch, but on some platforms
+	  multiplexer/demultiplexer switch is used to route the data lines on
+	  the USB connector between separate USB host and device controllers.
+
+	  Say Y here if your USB connectors support both device and host roles.
+	  To compile the driver as module, choose M here: the module will be
