From 6dd612e3d7e0c76f863efaddae4738fadc461f72 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 24 Dec 2013 21:26:18 +0800 Subject: [PATCH] ARM: dts: sun7i: external clock outputs This commit adds the two external clock outputs available on A20 to its device tree. A dummy fixed factor clock is also added to serve as the first input of the clock outputs, which according to AW's A20 user manual, is the 24MHz oscillator divided by 750.
