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.
