Subject: [PATCH] ARM: sunxi: dts: split IR pins for A10 and A20
Date: Tue, 28 Apr 2015 20:04:47 +0200 [thread overview]
Message-ID: <1430244287-29309-1-git-send-email-codekipper@gmail.com> (raw)
From: Marcus Cooper <codekipper-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
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.
