[PATCH] ARM: sunxi: dts: split IR pins for A10 and A20

Tue Apr 28 11:04:47 PDT 2015
From: Marcus Cooper <codekipper at gmail.com>
Currently none of the target boards nor the driver supports
IR TX. However this pin is used in a few instances as a GPIO.
Split the pin ctrl descriptions so that only the IR RX is
configured to be used.
