+Subject: [PATCH] ARM: dts: sun7i: Add pin muxing options for clock outputs
+
+This patch adds the clock output pin options on the A20.
+The 2 pins can output a configurable clock to be used by
+external modules. This is used on the CubieTruck, to supply
+a 32768 Hz low power clock to the onboard Wifi+BT module.
