#     Merge tag 'gpio-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
#     
#     Pull GPIO updates from Linus Walleij:
#      "This is the bulk of the GPIO changes for the v5.11 kernel cycle:
#     
#       Core changes:
#     
#        - Retired the old set-up function for GPIO IRQ chips. All chips now
#          use the template struct gpio_irq_chip and pass that to the core to
#          be set up alongside the gpio_chip. We can finally get rid of the
#          old cruft.
#     
#        - Some refactoring and clean up of the core code.
#     
#        - Support edge event timestamps to be stamped using REALTIME (wall
#          clock) timestamps. We have found solid use cases for this, so we
#          support it.
#     
#       New drivers:
#     
#        - MStar MSC313 GPIO driver.
#     
#        - HiSilicon GPIO driver.
#     
#       Driver improvements:
#     
#        - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
#     
#        - The mockup driver can now be probed from the device tree which is
#          pretty useful for virtual prototyping of devices.
#     
#        - The Rcar driver now supports .get_multiple()
#     
#        - The MXC driver dropped some legacy and became a pure device tree
#          client.
#     
#        - The Exar driver was moved over to the IDA interface for
#          enumerating, and also switched over to using regmap for register
#          access"
