Merge tag 'gpio-updates-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull gpio updates from Bartosz Golaszewski:
 "We mostly have various improvements and refactoring all over the place
  but also some interesting new features - like the virtio GPIO driver
  that allows guest VMs to use host's GPIOs. We also have a new/old GPIO
  driver for rockchip - this one has been split out of the pinctrl
  driver.

  Summary:

   - new driver: gpio-virtio allowing a guest VM running linux to access
     GPIO lines provided by the host

   - split the GPIO driver out of the rockchip pin control driver

   - add support for a new model to gpio-aspeed-sgpio, refactor the
     driver and use generic device property interfaces, improve property
     sanitization

   - add ACPI support to gpio-tegra186

   - improve the code setting the line names to support multiple GPIO
     banks per device

   - constify a bunch of OF functions in the core GPIO code and make the
     declaration for one of the core OF functions we use consistent
     within its header

   - use software nodes in intel_quark_i2c_gpio

   - add support for the gpio-line-names property in gpio-mt7621

   - use the standard GPIO function for setting the GPIO names in
     gpio-brcmstb

   - fix a bunch of leaks and other bugs in gpio-mpc8xxx

   - use generic pm callbacks in gpio-ml-ioh

   - improve resource management and PM handling in gpio-mlxbf2

   - modernize and improve the gpio-dwapb driver

   - coding style improvements in gpio-rcar

   - documentation fixes and improvements

   - update the MAINTAINERS entry for gpio-zynq

   - minor tweaks in several drivers"
