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