Merge tag 'gpio-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux...

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.9 kernel cycle.

  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.

  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"
