		Binding for TI/National Semiconductor LP55xx Led Drivers

		Required properties:
		- compatible: one of
		national,lp5521
		national,lp5523
		ti,lp55231
		ti,lp5562
		ti,lp8501

		- 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:
		- enable-gpio: GPIO attached to the chip's enable pin
		- label: Used for naming LEDs
		- pwr-sel: LP8501 specific property. Power selection for output channels.
		0: D1~9 are connected to VDD
		1: D1~6 with VDD, D7~9 with VOUT
		2: D1~6 with VOUT, D7~9 with VDD
		3: D1~9 are connected to VOUT

		Alternatively, each child can have a specific channel name and trigger:
		- chan-name (optional): name of channel
		- linux,default-trigger (optional): see
		Documentation/devicetree/bindings/leds/common.txt

		example 1) LP5521
		3 LED channels, external clock used. Channel names are 'lp5521_pri:channel0',
		'lp5521_pri:channel1' and 'lp5521_pri:channel2', with a heartbeat trigger
		on channel 0.

		lp5521@32 {
		compatible = "national,lp5521";
		reg = <0x32>;
		label = "lp5521_pri";
		clock-mode = /bits/ 8 <2>;

		chan0 {
		led-cur = /bits/ 8 <0x2f>;
		max-cur = /bits/ 8 <0x5f>;
		linux,default-trigger = "heartbeat";
		};

		chan1 {
		led-cur = /bits/ 8 <0x2f>;
		max-cur = /bits/ 8 <0x5f>;
		};

		chan2 {
		led-cur = /bits/ 8 <0x2f>;
		max-cur = /bits/ 8 <0x5f>;
		};
		};

		example 2) LP5523
		9 LED channels with specific name. Internal clock used.
		The I2C slave address is configurable with ASEL1 and ASEL0 pins.
		Available addresses are 32/33/34/35h.

		ASEL1 ASEL0 Address

		chan8 {
		chan-name = "d9";
		led-cur = /bits/ 8 <0x14>;
		max-cur = /bits/ 8 <0x20>;
		};
		};

		example 3) LP5562
		4 channels are defined.

		lp5562@30 {
		compatible = "ti,lp5562";
		reg = <0x30>;
		clock-mode = /bits/8 <2>;

		led-cur = /bits/ 8 <0x20>;
		max-cur = /bits/ 8 <0x60>;
		};
		};

		example 4) LP8501
		9 channels are defined. The 'pwr-sel' is LP8501 specific property.
		Others are same as LP5523.

		lp8501@32 {
		compatible = "ti,lp8501";
		reg = <0x32>;
		clock-mode = /bits/ 8 <2>;
		pwr-sel = /bits/ 8 <3>; /* D1~9 connected to VOUT */
