gpiolib: legacy: Kill GPIOF_DIR_* definitions

2024-09-02T09:47:06+00:00

Besides the fact that (old) drivers use wrong definitions, e.g., GPIOF_DIR_IN instead of GPIOF_IN, shrink the legacy definitions by killing those GPIOF_DIR_* completely.

gpio: Remove legacy API documentation

2024-05-27T14:50:03+00:00

In order to discourage people to use old and legacy GPIO APIs remove the respective documentation completely. It also helps further cleanups of the legacy GPIO API leftovers, which is ongoing task.

gpiolib: Get rid of never false gpio_is_valid() calls

2024-04-17T20:46:44+00:00

In the cases when gpio_is_valid() is called with unsigned parameter the result is always true in the GPIO library code, hence the check for false won't ever be true. Get rid of such calls. While at it, move GPIO device base to be unsigned to clearly show it won't ever be negative. This requires a new definition for the maximum GPIO number in the system.

gpiolib: Clean up headers

2023-03-06T10:33:02+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 Signed-off-by: Andy Shevchenko

gpiolib: remove legacy gpio_export()

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

There are only a handful of users of gpio_export() and related functions. As these are just wrappers around the modern gpiod_export() helper, remove the wrappers and open-code the gpio_to_desc in all callers to shrink the legacy API.
