Merge tag 'gpio-updates-for-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We have a single new driver, support for a bunch of new models,
  improvements in drivers and core gpiolib code as well device-tree
  bindings changes.

  Summary:

  New driver:
   - IMX System Controller Unit GPIOs

  GPIO core:
   - add fdinfo output for the GPIO character device file descriptors
     (allows user-space to determine which processes own which GPIO
     lines)
   - improvements to OF GPIO code
   - new quirk for Asus UM325UAZ in gpiolib-acpi
   - new quirk for Freescale SPI in gpiolib-of

  Driver improvements:
   - add a new macro that reduces the amount of boilerplate code in ISA
     drivers and use it in relevant drivers
   - support two new models in gpio-pca953x
   - support new model in gpio-f7188x
   - convert more drivers to use immutable irq chips
   - other minor tweaks

  Device-tree bindings:
   - add DT bindings for gpio-imx-scu
   - convert Xilinx GPIO bindings to YAML
   - reference the properties from the SPI peripheral device-tree
     bindings instead of providing custom ones in the GPIO controller
     document
   - add parsing of GPIO hog nodes to the DT bindings for gpio-mpfs-gpio
   - relax the node name requirements in gpio-stmpe
   - add new models for gpio-rcar and gpio-pxa95xx
   - add a new vendor prefix: Diodes (for Diodes, Inc.)

  Misc:
   - pulled in the immutable branch from the x86 platform drivers tree
     including support for a new simatic board that depends on GPIO
     changes"
