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).

  Misc:

   - Drop a FMC remnant file <linux/ipmi-fru.h>

   - A slew of fixes"

maintainers:

  - Paul Kocialkowski <paul.kocialkowski@bootlin.com>



description: |

  The LogiCVC GPIO describes the GPIO block included in the LogiCVC display

  controller. These are meant to be used for controlling display-related

  signals.



  The controller exposes GPIOs from the display and power control registers,

  which are mapped by the driver as follows:

  - GPIO[4:0] (display control) mapped to index 0-4

  - EN_BLIGHT (power control) mapped to index 5

  - EN_VDD (power control) mapped to index 6

  - EN_VEE (power control) mapped to index 7

  - V_EN (power control) mapped to index 8
