From 40b1708f72af8106f9418a8416fa77238ec29eb8 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 17 Nov 2013 02:19:40 +0100 Subject: ARM: dts: imx53: Fix backlight for M53EVK Remove the PWM backlight pin from the hog pins list, so it doesn't collide with the PWM pin group. Moreover, add dummy regulator for the backlight so that the backlight driver probes correctly.
