4 Subject: [PATCH] ARM: dts: sun7i: external clock outputs
6 This commit adds the two external clock outputs available on A20 to
7 its device tree. A dummy fixed factor clock is also added to serve as
8 the first input of the clock outputs, which according to AW's A20 user
9 manual, is the 24MHz oscillator divided by 750.
