Hi Linus,

Here's the pull-request for this cycle from the GPIO subsystem. 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, hence the pull from the
pinctrl tree you can see in my branch. Another merge in the tree is from Andy
for the intel drivers. Details are in the signed tag.

Please pull!
Bartosz

  gpio: mpc8xxx: Use 'devm_gpiochip_add_data()' to simplify the code and avoid a leak (2021-08-31 12:10:24 +0200)

----------------------------------------------------------------
gpio updates for v5.15

- 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
