[PATCH v2 0/3] pinctrl/GPIO driver for Apple SoCs

From: Joey Gouly <joey.gouly@arm.com>

Hi all,

Here is the v2 patchset for the Apple pinctrl/GPIO driver.

I'll be away for a week, and won't be able to reply to e-mails, but I
wanted to send this out now to keep progressing and maybe people can test with
the updates.

Changes since v1 [1]:
  - Removed USE_*_GENERIC_FN defines
  - Use apple,npins instead of gpio-ranges + dt-binding commit
  - Use _relaxed accesors
  - Use per-irq context data + gpiolib core commit
  - Moved some fields from apple_gpio_pinctrl to be local variables in 
    apple_gpio_pinctrl_probe
  - Simplify the register shadowing, by simply mirroring the entire
    value of the register.
  - Ran checkpatch.pl / clang-format to fix style issues.

There is a branch here with the driver:
  https://gitlab.arm.com/linux-arm/jg-open/-/commits/pinctrl_apple_v2

Thanks,
Joey

note: For those that have been testing this with PCIe etc, you will
probably want to also include the last commit in the following branch, as I
dropped the clock references in the code (due to the switch to power domains):
