From 0ed797f70567dedceb26afd01f0cafd7b785f483 Mon Sep 17 00:00:00 2001 From: Andi Shyti Date: Fri, 10 Feb 2017 11:22:38 +0900 Subject: [PATCH] arm64: dts: exynos: Enable ir-spi in the TM2 and TM2E boards Add the device tree node for the ir-spi driver which enables the IR LED for remote controlling. This patch sets first the GPR3[3] gpio line as a regulator-fixed for enabling an external regulator which powers the IR LED. Removes also the default assignment of GPG3[7] related to the MOSI line of the SPI3 bus.
