From 771e4feb273a98aeccd3e0c3edd05ecde513d280 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Sun, 5 Mar 2017 20:11:58 -0800 Subject: [PATCH] ARM: dts: omap4-droid4: Add LCD backlight The TI LMU driver has not yet been merged, but the device tree binding for TI LMU drivers has been acked already earlier by Rob Herring . So it should be safe to apply to cut down the number of pending patches.
