ltc2978



Required properties:

- compatible: should contain one of:

  * "lltc,ltc2974"

  * "lltc,ltc2977"

  * "lltc,ltc2978"

  * "lltc,ltc3880"

  * "lltc,ltc3883"

  * "lltc,ltm4676"

- reg: I2C slave address



Optional properties:

- regulators: A node that houses a sub-node for each regulator controlled by

  the device. Each sub-node is identified using the node's name, with valid

  values listed below. The content of each sub-node is defined by the

  standard binding for regulators; see regulator.txt.



Valid names of regulators depend on number of supplies supported per device:

  * ltc2974 : vout0 - vout3

  * ltc2977 : vout0 - vout7

  * ltc2978 : vout0 - vout7

  * ltc3880 : vout0 - vout1

  * ltc3883 : vout0

  * ltm4676 : vout0 - vout1



Example:

ltc2978@5e {

	compatible = "lltc,ltc2978";

	reg = <0x5e>;

	regulators {

		vout0 {

			regulator-name = "FPGA-2.5V";

		};

		vout2 {

			regulator-name = "FPGA-1.5V";

		};

	};

};
