pinctrl: add more pinconf/pinctrl definitions

2026-07-08T19:29:18Z

These pinconf/pinctrl definitions will be used by the next patches. The definitions was taken from public headers of linux-7.0. It's used by several linux pinctrl drivers, so it might be helpful for U-Boot as well. Pinconf definitions are placed near the corresponding U-Boot definitions in file include/dm/pinctrl.h. Pin/group/function definitions stored within the same path as in linux (include/linux/pinctrl/pinctrl.h). Signed-off-by: Mikhail Kshevetskiy Reviewed-by: David Lechner

headers: don't depend on errno.h being available

2024-01-24T16:12:11Z

These headers follow the pattern: | #if CONFIG_IS_ENABLED(FANCY_FEATURE) | void foo(void); | #else | static inline void foo(void) { return -ENOSYS; } | #endif In the #else path ENOSYS is used, however linux/errno.h is not included. If errno.h has not been included already the compiler errors out even if the inline function is not referenced. Make those headers self contained.

pinctrl: Increase size of pinmux status buffer

2023-10-09T08:25:32Z

For Xilinx ZynqMP SOC new parameter was added and now it can set 7 parameters for its pins. Pinmux status command will print the status of these parameters for each pin. But current print buffer length is only 80 characters long, increase it to 90 to print all the parameters without truncation.

pinctrl: Add third argument label for pinctrl_gpio_request() function

2022-07-28T13:17:45Z

This change allows to use pinctrl_gpio_request() function as a direct pointer for dm_gpio_ops's .request callback. Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese

pinctrl: Add new function pinctrl_generic_set_state_prefix()

2022-07-28T06:41:44Z

This new function pinctrl_generic_set_state_prefix() behaves like pinctrl_generic_set_state() but it takes third string argument which is used as the prefix for each device tree string property. This is needed for Marvell pinctrl drivers, becase Linux device tree files have pinmux properties prefixed by "marvell," string. This change allows to use generic U-Boot pinctrl functions for Armada 38x pinctrl driver without need to copy+paste of the majority U-Boot pinctrl code.

Xilinx ZynqMP SOC can set 6 parameters for its pins. pinmux status command will print the status of these parameters for each pin. But current print buffer length is only 40 characters long, increase it to 80 to print all the parameters.

dm: pinctrl: Use explicit values for enums

2022-03-07T07:49:42Z

Based on discussion at https://lore.kernel.org/r/20200318125003.GA2727094@kroah.com we got recommendation to use explicit values for all enums. So, add explicit values to all pinctrl related enums for readability.

cmd: pinmux: update result of do_status

2021-07-23T11:13:25Z

Update the result of do_status and always returns a CMD_RET_ value (-ENOSYS was a possible result of show_pinmux). This patch also adds pincontrol name in error messages (dev->name) and treats correctly the status sub command when pin-controller device is not selected.

pinctrl: Reformat documentation in dm/pinctrl.h

2020-10-08T15:42:36Z

This normalizes the documentation to conform to kernel-doc style [1]. It also moves the documentation for pinctrl_ops inline, and adds argument and return-value documentation. I have kept the usual function style for these comments. I could not find any existing examples of function documentation inside structs.
