pinctrl: allow to mark pin functions as requestable GPIOs

2025-09-08T12:22:58+00:00

The name of the pin function has no real meaning to pinctrl core and is there only for human readability of device properties. Some pins are muxed as GPIOs but for "strict" pinmuxers it's impossible to request them as GPIOs if they're bound to a devide - even if their function name explicitly says "gpio". Add a new field to struct pinfunction that allows to pass additional flags to pinctrl core. While we could go with a boolean "is_gpio" field, a flags field is more future-proof. If the PINFUNCTION_FLAG_GPIO is set for a given function, the pin muxed to it can be requested as GPIO even on strict pin controllers. Add a new callback to struct pinmux_ops - function_is_gpio() - that allows pinmux core to inspect a function and see if it's a GPIO one. Provide a generic implementation of this callback.

pinctrl: Constify pointers to 'pinctrl_desc'

2025-06-18T11:26:36+00:00

Pin controller core code only stores the pointer to 'struct pinctrl_desc' and does not modify it anywhere. The pointer can be changed to pointer to const which makes the code safer, explicit and later allows constifying 'pinctrl_desc' allocations in individual drivers.

pinctrl: Convert unsigned to unsigned int

2023-12-04T14:32:42+00:00

Simple type conversion with no functional change implied. While at it, adjust indentation where it makes sense. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20231129161459.1002323-24-andriy.shevchenko@linux.intel.com Signed-off-by: Linus Walleij

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.
