Subject: [PATCH 1/2] ARM: i.MX: add low level gpio helpers for i.MX8M
Date: Fri, 4 Dec 2020 18:40:44 +0100 [thread overview]
Message-ID: <20201204174045.27340-1-a.fatoum@pengutronix.de> (raw)
Like many GPIO controllers of times past, the i.MX8M is also compatible
with the i.MX31 GPIO controller. Add GPIO helpers for low-level code to
use.
