    1 * Texas Instruments - LM3692x Highly Efficient White LED Driver
    2 
    3 The LM3692x is an ultra-compact, highly efficient,
    4 white-LED driver designed for LCD display backlighting.
    5 
    6 The main difference between the LM36922 and LM36923 is the number of
    7 LED strings it supports.  The LM36922 supports two strings while the LM36923
    8 supports three strings.

   10 Required properties:
   11         - compatible:
   12                 "ti,lm36922"
   13                 "ti,lm36923"
   14         - reg :  I2C slave address
   15         - #address-cells : 1
   16         - #size-cells : 0
   17 
   18 Optional properties:
   19         - enable-gpios : gpio pin to enable/disable the device.
   20         - vled-supply : LED supply
   21         - ti,ovp-microvolt: Overvoltage protection in
   22             micro-volt, can be 17000000, 21000000, 25000000 or
   23             29000000. If ti,ovp-microvolt is not specified it
   24             defaults to 29000000.
   25 
   26 Required child properties:
   27         - reg : 0 - Will enable all LED sync paths
   28                 1 - Will enable the LED1 sync
   29                 2 - Will enable the LED2 sync
   30                 3 - Will enable the LED3 sync (LM36923 only)
