[v3,00/12] gpiolib cleanups

Message

Andy Shevchenko Feb. 7, 2023, 2:29 p.m. UTC

These are some older patches Arnd did last year, rebased to
linux-next-20230207. On top there are Andy's patches regarding
similar topic.

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 v3:
- reworked touchscreen patch in accordance with Dmitry's comments
- rebased on the latest Linux Next
- added on top Andy's series

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

Andy Shevchenko (5):
  gpio: aggregator: Add missing header(s)
  gpiolib: Drop unused forward declaration from driver.h
  gpiolib: Deduplicate forward declarations in consumer.h
  gpiolib: Group forward declarations in consumer.h
  gpiolib: Clean up headers

Arnd Bergmann (7):
  gpiolib: remove empty asm/gpio.h files
  gpiolib: coldfire: remove custom asm/gpio.h
  gpiolib: remove asm-generic/gpio.h
  gpiolib: remove gpio_set_debounce
  gpiolib: remove legacy gpio_export
  gpiolib: split linux/gpio/driver.h out of linux/gpio.h
  gpiolib: split of_mm_gpio_chip out of linux/of_gpio.h
