[v4,00/18] gpiolib cleanups

  These are some older patches Arnd did last year, rebased to
linux-next-20230208. On top there are Andy's patches regarding
similar topic. The series starts with Linus Walleij's patches.

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.

The idea is to get an immutable branch and route the whole series
via GPIO tree.

Changes in v4:
- incorporated Linus Walleij's patches
- reworked touchscreen patch to have bare minimum changes (Dmitry)
- described changes in gpio-aggregator in full (Geert)
- addressed compilation errors (LKP)
- added tags (Geert, Lee, Vincenzo)

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 (7):
  gpio: aggregator: Add missing header(s)
  gpio: reg: Add missing header(s)
  gpio: regmap: 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

Linus Walleij (4):
  ARM: orion/gpio: Use the right include
  ARM: s3c24xx: Use the right include
  hte: tegra-194: Use proper includes
  gpiolib: Make the legacy <linux/gpio.h> consumer-only

Andy,

looks like this series has all the acks it needs but I decided to not
send it in the upcoming merge window, I'd prefer it gets some time in
next so I'll let it sit until the next release cycle.

Ah, I forgot to mention that this is for the next cycle (v6.4).
Hence it's fine. (Moreover it's based on Linux Next, so it will
fail compilation in any certain tree except that one.)

I will create an immutable branch after v6.3-rc1 is out.
