pinctrl: Introduce struct pinfunction and PINCTRL_PINFUNCTION() macro

2022-12-30T08:22:37+00:00

There are many pin control drivers define their own data type for pin function representation which is the same or embed the same data as newly introduced one. Provide the data type and convenient macro for all pin control drivers. Signed-off-by: Andy Shevchenko Reviewed-by: Linus Walleij Acked-by: Mika Westerberg

pinctrl: Put space between type and data in compound literal

2022-11-10T09:53:25+00:00

It's slightly better to read when compound literal data and type are separated by a space. Signed-off-by: Andy Shevchenko Reviewed-by: Basavaraj Natikar Link: https://lore.kernel.org/r/20221109152356.39868-1-andriy.shevchenko@linux.intel.com Signed-off-by: Linus Walleij

pinctrl: Clean up headers

2022-10-24T14:06:48+00:00

There is a few things done: - include only the headers we are direct user of - when pointer is in use, provide a forward declaration - add missing headers - group generic headers and subsystem headers - sort each group alphabetically While at it, fix some awkward indentations.

pinctrl: Add pingroup and define PINCTRL_PINGROUP

2022-06-15T13:54:20+00:00

Add 'struct pingroup' to represent pingroup and 'PINCTRL_PINGROUP' macro for inline use. Both are used to manage and represent larger number of pingroups.

pinctrl: Remove hole in pinctrl_gpio_range

2020-11-05T13:56:50+00:00

On 64-bit platforms, pointer size and alignment are 64-bit, hence two 4-byte holes are present before the pins and gc members of the pinctrl_gpio_range structure. Get rid of these holes by moving the pins pointer. This reduces kernel size of an arm64 Rockchip kernel by ca. 512 bytes.

pinctrl: Define of_pinctrl_get() dummy for !PINCTRL

2020-03-31T20:08:54+00:00

Currently, the of_pinctrl_get() dummy is only defined for !OF, which can still cause build failures on configurations with OF enabled but PINCTRL disabled. Make sure to define the dummy if either OF or PINCTRL are not enabled.

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

pinctrl: remove unneeded #ifdef around declarations

2019-06-25T08:49:18+00:00

What is the point in surrounding the whole of declarations with ifdef like this? #ifdef CONFIG_FOO int foo(void); #endif If CONFIG_FOO is not defined, all callers of foo() will fail with implicit declaration errors since the top Makefile adds -Werror-implicit-function-declaration to KBUILD_CFLAGS. This breaks the build earlier when you are doing something wrong. That's it. Anyway, it will fail to link since the definition of foo() is not compiled. In summary, these ifdef are unneeded.

2019-06-12T07:10:54+00:00

This function was used by pin_request() to pointlessly double-check the pin validity, and it was the only user ever. Since commit d2f6a1c6fb0e ("pinctrl: remove double pin validity check."), no one has ever used it. Signed-off-by: Masahiro Yamada Signed-off-by: Linus Walleij
