[PATCH V2 7/9] gpio/rockchip: rk_gpio support v2 gpio controller
Chris Morgan
macroalpha82 at gmail.com
Mon Feb 13 23:27:40 CET 2023
From: Chris Morgan <macromorgan at hotmail.com>
Add support for the newer GPIO controller used by the rk356x series,
as well as the pinctrl device for the rk356x series. The GPIOv2
controller has a write enable bit for some registers which differs
from the older versions of the GPIO controller.
