gpio: remove of_get_named_gpio() and

2026-03-09T09:25:34+00:00

All in-tree consumers have been converted to the descriptor-based API. Remove the deprecated of_get_named_gpio() helper, delete the header, and drop the corresponding entry from MAINTAINERS. Also remove the completed TODO item for this cleanup.

gpiolib: split of_mm_gpio_chip out of linux/of_gpio.h

2023-03-06T10:33:01+00:00

This is a rarely used feature that has nothing to do with the client-side of_gpio.h. Split it out with a separate header file and Kconfig option so it can be removed on its own timeline aside from removing the of_gpio consumer interfaces.

There are no more users of these APIs in the mainline kernel, remove them. This leaves of_get_named_gpio() as the only legacy OF-specific API. Signed-off-by: Dmitry Torokhov Reviewed-by: Andy Shevchenko Signed-off-by: Bartosz Golaszewski

On top of looking at PULL_UP and PULL_DOWN flags, also look at PULL_DISABLE and set the appropriate GPIO flag. The GPIO core will then pass down this to controllers that support it. Signed-off-by: Nuno Sá Reviewed-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

gpiolib: constify passed device_node pointer

2021-08-05T19:21:58+00:00

Several gpiolib functions receive pointer to struct device_node which is later passed to OF functions. These OF functions accept already pointer to const, so gpiolib can follow similar approach to indicate they are not modifying the struct device_node.
