Subject: [linux-sunxi] ARM: sunxi: dts: split IR pins for A10 and A20

From: [email-masked] (codekipper at gmail.com)
Date: Sat, 2 May 2015 13:36:20 +0200

From: Marcus Cooper <[email-masked]>

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.
