+Binding for TI/National Semiconductor LP55xx Led Drivers
+
+Required properties:
+- compatible: "national,lp5521" or "national,lp5523" or "ti,lp5562"
+- reg: I2C slave address
+- clock-mode: Input clock mode, (0: automode, 1: internal, 2: external)
+
+Each child has own specific current settings
+- led-cur: Current setting at each led channel (mA x10, 0 if led is not connected)
+- max-cur: Maximun current at each led channel.
+
+Optional properties:
+- label: Used for naming LEDs
+
+Alternatively, each child can have specific channel name
+- chan-name: Name of each channel name
+
+example 1) LP5521
+3 LED channels, external clock used. Channel names are 'lp5521_pri:channel0',
+'lp5521_pri:channel1' and 'lp5521_pri:channel2'
