Subject: [PATCH 3/5] ARM: dts: sun5i: q8-tablet: Add LCD Panel enable GPIO
Date: Sun, 27 Jan 2019 22:48:36 +0800 [thread overview]
Message-ID: <20190127144838.3578-4-wens@csie.org> (raw)
In-Reply-To: <20190127144838.3578-1-wens@csie.org>
Now that we support the AXP209 GPIOs, we can toggle the LCD panel enable
line. Add the GPIO phandle to the panel.
