[PATCH v6 2/2] leds: rt5033: Add RT5033 Flash led device driver
From: Ingi Kim
Date: Wed Nov 25 2015 - 05:23:16 EST
This patch adds device driver of Richtek RT5033 PMIC.
The RT5033 Flash LED Circuit is designed for one or two LEDs driving
for torch and strobe applications, it provides an I2C software command
to trigger the torch and strobe operation.
Each of LED outputs can contorl a separate LED sharing their setting,
and can be connected together for a single connected LED.
One LED is represented by one child node.
