[PATCH v2 0/7] gpiolib cleanups

[Arnd Bergmann <arnd@xxxxxxxxxx>]

From: Arnd Bergmann <arnd@xxxxxxxx>

These are some older patches I did last year, rebased to linux-next-20230127.

The main goal is to remove some of the legacy bits of the gpiolib
interfaces, where the corner cases are easily avoided or replaced
with gpio descriptor based interfaces.

Changes in v2:
 - dropped patch 8 after Andy's identical patch was merged
 - rebase on latest gpio tree
 - leave unused gpio_cansleep() in place for now
 - address feedback from Andy Shevchenko
