Subject: [PATCH V2 7/9] gpio/rockchip: rk_gpio support v2 gpio controller
Date: Mon, 13 Feb 2023 16:27:40 -0600	[thread overview]
Message-ID: <20230213222742.135093-8-macroalpha82@gmail.com> (raw)
In-Reply-To: <20230213222742.135093-1-macroalpha82@gmail.com>

From: Chris Morgan <macromorgan@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.
