Linus Torvalds fa889d8555 This is the bulk of GPIO changes for the v5.6 kernel cycle
Core changes:
 
 - Document the usecases for the kernelspace vs userspace
   handling of GPIOs.
 
 - Handle MSI (message signalled interrupts) properly in the
   core hierarchical irqdomain code.
 
 - Fix a rare race condition while initializing the descriptor
   array.
 
 New drivers:
 
 - Xylon LogiCVC GPIO driver.
 
 - WDC934x GPIO controller driver.
 
 Driver improvements:
 
 - Implemented suspend/resume in the Tegra driver.
 
 - MPC8xx edge detection fixup.
 
 - Properly convert ThunderX to use hierarchical irqdomain
   with GPIOLIB_IRQCHIP on top of the revert of the previous
   buggy switchover. This time it works (hopefully).
 
 Misc:
 
 - Drop a FMC remnant file <linux/ipmi-fru.h>
 
 - A slew of fixes.

Merge tag 'gpio-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.6 kernel cycle.

  This is a pretty calm cycle so far, nothing special going on really.
  Some more changes will come in from the irqchip and pin control trees.

  I also deleted an orphan include file for FMC that was dangling since
  subsystem was removed.

  Core changes:

   - Document the usecases for the kernelspace vs userspace handling of
     GPIOs.

   - Handle MSI (message signalled interrupts) properly in the core
     hierarchical irqdomain code.

   - Fix a rare race condition while initializing the descriptor array.

  New drivers:

   - Xylon LogiCVC GPIO driver.

   - WDC934x GPIO controller driver.

  Driver improvements:

   - Implemented suspend/resume in the Tegra driver.

   - MPC8xx edge detection fixup.

   - Properly convert ThunderX to use hierarchical irqdomain with
     GPIOLIB_IRQCHIP on top of the revert of the previous buggy
     switchover. This time it works (hopefully).
