From f3a50c26f33a4627e5d3e35f80db3f22a5375237 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 24 Dec 2013 21:26:20 +0800 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.
