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'



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>;

	};



	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.

		led-cur = /bits/ 8 <0x14>;

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

	};



	chan7 {

		chan-name = "d8";

		led-cur = /bits/ 8 <0x14>;

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

	};



	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>;



	chan0 {

		chan-name = "R";

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

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

	};



	chan2 {

		chan-name = "B";

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

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

	};



	chan3 {

		chan-name = "W";

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

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

	};
