Subject: [PATCH] arm64: dts: rockchip: Add pinctrl entry for 32k clock on rk3399
Date: Thu, 1 Sep 2016 16:53:22 -0700 [thread overview]
Message-ID: <1472774002-25986-1-git-send-email-dianders@chromium.org> (raw)
On some rk3399 boards GPIO0_A0 is hooked up to a 32 kHz clock. This can
be used as the source for various clocks in the system.
Add a pinmux so boards can get this pin properly configured.
