Subject: [PATCH 2/4] ARM: dts: sun8i: Add PWM channel 0 pinmux setting for A23/A33
Date: Fri, 18 Sep 2015 15:35:37 +0800	[thread overview]
Message-ID: <1442561739-6824-3-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1442561739-6824-1-git-send-email-wens@csie.org>

The PWM controller has 2 outputs, with one usable pin for each.

Add a pinmux setting for the first channel. This is often used
for backlight dimming on tablets.
