From b3b97473ee07ae8904e9d8fe02914de2188d302c Mon Sep 17 00:00:00 2001 From: "Jett.Zhou" Date: Tue, 28 Feb 2012 10:59:29 +0800 Subject: [PATCH] led: Modified power control of pm860x led Since several sub modules such as backlight, leds and vibrator depend on the refernce group and internal oscillator in pm8606, so modified the power control of led in pm8606 by unified interface.
