NXP LED segment driver devicetree bindings



Required properties:



 - compatible               : "nxp,pca9956b" for PCA9956b

 - nxp,mode1                : MODE1 register

 - nxp,mode2                : MODE2 register

 - nxp,ledout0~5            : LED output state registers

 - nxp,defaultiref          : LED output gain control default value



LED sub-node properties:

 - reg: number of LED line, 0 to 24

 - label: (optional) name of LED

 - linux,default-trigger : (optional)



Example:

pca9956b {

	/* I2C version */

	reg = <0x7d>;



	/* nxp-ledseg properties */



	compatible    = "nxp,pca9956b";



	pinctrl-names = "default";

	pinctrl-0     = <&pca9956b_pins>;



	pca9956b,support_initialize = <1>;

	pca9956b,mode1 = <0x09>;

	pca9956b,mode2 = <0x05>;



	pca9956b,ledout0 = <0xaa>;

	pca9956b,ledout1 = <0xaa>;

	pca9956b,ledout2 = <0xaa>;

	pca9956b,ledout3 = <0xff>;

	pca9956b,ledout4 = <0xff>;

	pca9956b,ledout5 = <0xff>;

	pca9956b,defaultiref = <0x2f>;



	out0@0 {

		label = "ledsec1_b";

		reg = <0x0>;

	};



	out1@1 {

		label = "ledsec1_g";

		reg = <0x1>;

	};



	out5@5 {

		label = "ledsec1_g";

		reg = <0x5>;

		linux,default_trigger = "heartbeat";

	};
