2018-06-05pinctrl: madera: Add driver for Cirrus Logic Madera codecsRichard Fitzgerald1-0/+1
These codecs have a variable number of I/O lines each of which is individually selectable to a wide range of possible functions. The functionality is slightly different from the traditional muxed GPIO since most of the functions can be mapped to any pin (and even the same function to multiple pins). Most pins have a dedicated "alternate" function that is only available on that pin. The alternate functions are usually a group of signals, though it is not always necessary to enable the full group, depending on the alternate function and how it is to be used. The mapping between alternate functions and GPIO pins varies between codecs depending on the number of alternate functions and available pins.

2017-12-20pinctrl: mediatek: add pinctrl driver for MT7622 SoCSean Wang1-1/+1
Add support for pinctrl on MT7622 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. However, the IO core for the MT7622 SoC is completely distinct from anyone of previous MediaTek SoCs which already had support, such as the hardware internal, register address map and register detailed definition for each pin. Therefore, instead, the driver is being newly implemented by reusing generic methods provided from the core layer with GENERIC_PINCONF, GENERIC_PINCTRL_GROUPS, and GENERIC_PINMUX_FUNCTIONS for the sake of code simplicity and rid of superfluous code. Where the function of pins determined by groups is utilized in this driver which can help developers less confused with what combinations of pins effective on the SoC and even reducing the mistakes during the integration of those relevant boards. As the gpio_chip handling is also only a few lines, the driver also implements the gpio functionality directly through GPIOLIB.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2017-05-22pinctrl: add ZTE ZX pinctrl driver supportShawn Guo1-0/+1
The pin controller on ZTE ZX platforms is kinda of hybrid. It consists of a main controller and an auxiliary one. For example, on ZX296718 SoC, the main controller is TOP_PMM and the auxiliary one is AON_IOCFG. Both controllers work together to control pin multiplexing and configuration. For most of pins, the pinmux function is controlled by main controller only, and this type of pins are meant by term 'TOP pins'. For other pins, the pinmux is controlled by both main and auxiliary controllers, as the available multiplexing functions for the pin spread in both controllers. This type of pins are called 'AON pins'. Though pinmux implementation is quite different, pinconf is same for both types of pins. Both are controlled by auxiliary controller, i.e. AON_IOCFG on ZX296718. The patch adds the ZTE ZX core pinctrl driver to support this hybrid pin controller as well as ZX296718 SoC specific pin data.

2017-01-09pinctrl: Introduce TI IOdelay configuration driverNishanth Menon1-0/+1
SoC family such as DRA7 family of processors have, in addition to the regular muxing of pins (as done by pinctrl-single), a separate hardware module called IODelay which is also expected to be configured. The "IODelay" module has it's own register space that is independent of the control module and the padconf register area. With recent changes to the pinctrl framework, we can now support this hardware with a reasonably minimal driver by using #pinctrl-cells, GENERIC_PINCTRL_GROUPS and GENERIC_PINMUX_FUNCTIONS. It is advocated strongly in TI's official documentation considering the existing design of the DRA7 family of processors during mux or IODelay reconfiguration, there is a potential for a significant glitch which may cause functional impairment to certain hardware. It is hence recommended to do as little of muxing as absolutely necessary without I/O isolation (which can only be done in initial stages of bootloader). NOTE: with the system wide I/O isolation scheme present in DRA7 SoC family, it is not reasonable to do stop all I/O operations for every such pad configuration scheme. So, we will let it glitch when used in this mode. Even with the above limitation, certain functionality such as MMC has mandatory need for IODelay reconfiguration requirements, depending on speed of transfer. In these cases, with careful examination of usecase involved, the expected glitch can be controlled such that it does not impact functionality. In short, IODelay module support as a padconf driver being introduced here is not expected to do SoC wide I/O Isolation and is meant for a limited subset of IODelay configuration requirements that need to be dynamic and whose glitchy behavior will not cause functionality failure for that interface. IMPORTANT NOTE: we take the approach of keeping LOCK_BITs cleared to 0x0 at all times, even when configuring Manual IO Timing Modes. This is done by eliminating the LOCK_BIT=1 setting from Step of the Manual IO timing Mode configuration procedure. This option leaves the CFG_* registers unprotected from unintended writes to the CTRL_CORE_PAD_* registers while Manual IO Timing Modes are configured. This approach is taken to allow for a generic driver to exist in kernel world that has to be used carefully in required usecases.

2016-10-24pinctrl: Add SX150X GPIO Extender Pinctrl DriverNeil Armstrong1-0/+1
Since the I2C sx150x GPIO expander driver uses platform_data to manage the pins configurations, rewrite the driver as a pinctrl driver using pinconf to get/set pin configurations from DT or debugfs. The pinctrl driver is functionnally equivalent as the gpio-only driver and can use DT for pinconf. The platform_data confirmation is dropped. This patchset removed the gpio-only driver and selects the Pinctrl driver config instead. This patchset also migrates the gpio dt-bindings to pinctrl and add the pinctrl optional properties. The driver was tested with a SX1509 device on a BeagleBone black with interrupt support and on an X86_64 machine over an I2C to USB converter. This is a fixed version that builds and runs on non-OF platforms and on arm based OF. The GPIO version is removed and the bindings are also moved to the pinctrl bindings. Changes since v2 - rebased on v4.9-rc1 - removed MODULE_DEVICE_TABLE as in upstream bb411e771b0e ("gpio: sx150x: fix implicit assumption module.h is present") Changes since v1 - Fix Kconfig descriptions on pinctrl and gpio - Fix Kconfig dependency - Remove oscio support for non-789 devices - correct typo in dt bindings - remove probe reset for non-789 devices Changes since RFC - Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms - No more rely on OF_GPIO config - Moved and enhanced bindings to pinctrl bindings - Removed gpio-sx150x.c - Temporary select PINCTRL_SX150X when GPIO_SX150X - Temporary mark GPIO_SX150X as deprecated Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Peter Rosin <peda@axentia.se> Acked-by: Rob Herring <robh@kernel.org> ested-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-09-07pinctrl: Add core support for Aspeed SoCsAndrew Jeffery1-0/+1
The Aspeed SoCs typically provide more than 200 pins for GPIO and other functions. The signal enabled on a pin is determined on a priority basis, where a given pin can provide a number of different signal types. In addition to the priority levels, the Aspeed pin controllers describe the signal active on a pin by compound logical expressions involving multiple operators, registers and bits. Some difficulty arises as a pin's function bit masks for each priority level are frequently not the same (i.e. we cannot just flip a bit to change from a high to low priority signal), or even in the same register(s). Some configuration bits affect multiple pins, while in other cases the signals for a bus must each be enabled individually. Together, these features give rise to some complexity in the implementation. A more complete description of the complexities is provided in the associated header file. The patch doesn't implement pinctrl/pinmux/pinconf for any particular Aspeed SoC, rather it adds the framework for defining pinmux configurations.
