[PATCH v1 0/4] gpio: Unify the GPIO controller node check

[Andy Shevchenko]

There are handful of drivers perform the same check in different variations
over and over with a potential to make subtle mistakes. Unify the check by
providing a new helper and convert a few users as an example.

Andy Shevchenko (4):
  gpio: Split fwnode_is_gpiochip() helper
  gpio: shared: Replace open coded fwnode_is_gpiochip()
  pinctrl: ma35: Replace open coded fwnode_is_gpiochip()
  pinctrl: pistachio: Replace open coded fwnode_is_gpiochip()
