From 469a22e6bad725cbd3188f37f2d119c7c7eaf510 Mon Sep 17 00:00:00 2001 From: Marcus Cooper Date: Sat, 2 May 2015 13:36:20 +0200 Subject: [PATCH] ARM: sunxi: dts: split IR pins for A10 and A20 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.
