Required properties:
|
|
- compatible: should contain one of:
|
|
* "lltc,ltc2974"
|
|
* "lltc,ltc2975"
|
|
* "lltc,ltc2977"
|
|
* "lltc,ltc2978"
|
|
* "lltc,ltc2980"
|
|
* "lltc,ltc3880"
|
|
* "lltc,ltc3882"
|
|
* "lltc,ltc3883"
|
|
* "lltc,ltc3886"
|
|
* "lltc,ltc3887"
|
|
* "lltc,ltm2987"
|
|
* "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, ltc2975 : vout0 - vout3
|
|
* ltc2977, ltc2980, ltm2987 : vout0 - vout7
|
|
* ltc2978 : vout0 - vout7
|
|
* ltc3880, ltc3882, ltc3886 : 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";
|
|
};
|
|
};

};
