   4 Subject: [PATCH] pinctrl: sunxi: Add Allwinner A20 clock output pin functions
   5
   6 This patch adds the clock output pin functions 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.
