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

From: Andy Shevchenko

Date: Mon Aug 24 2026 - 03:52:08 EST


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()
