[GIT PULL] GPIO changes for the v5.9 merge window

[Linus Walleij]

Hi Linus,

here is the big slew of GPIO changes for the v5.9 merge window.

There is nothing too exciting in it, but a new macro that fixes a
build failure on a minor ARM32 platform that appeared yesterday
is part of it so we better merge it.

Please pull it in!

Yours,
Linus Walleij

  gpio: wcove: Request IRQ after all initialisation done (2020-08-04
01:25:02 +0200)

----------------------------------------------------------------
This is the bulk of GPIO changes for the v5.9 kernel cycle:

Core changes:

- Introduce the for_each_requested_gpio() macro to help in
  dependent code all over the place. Also patch a few locations
  to use it while we are at it.

- Split out the sysfs code into its own file.

- Split out the character device code into its own file, then
  make a set of refactorings and improvements to this code.
  We are setting the stage to revamp the userspace API a bit
  in the next cycle.

- Fix a whole slew of kerneldoc that was wrong or missing.

New drivers:

- The PCA953x driver now supports the PCAL9535.

Driver improvements:

- A host of incremental modernizations and improvements to the
  PCA953x driver.

- Incremental improvements to the Xilinx Zynq driver.

- Some improvements to the GPIO aggregator driver.

- I ran all over the place switching all threaded and other
  drivers requesting their own IRQ while using the core
  GPIO IRQ helpers to pass the GPIO irq chip as a template
  instead of calling the explicit set-up functions. Next merge
  window we may retire the old code altogether.
