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";
};
};
};
