1ltc2978
2
3Required properties:
4- compatible: should contain one of:
5 * "lltc,ltc2974"
6 * "lltc,ltc2975"
7 * "lltc,ltc2977"
8 * "lltc,ltc2978"
9 * "lltc,ltc2980"
10 * "lltc,ltc3880"
11 * "lltc,ltc3882"
12 * "lltc,ltc3883"
13 * "lltc,ltc3886"
14 * "lltc,ltc3887"
15 * "lltc,ltm2987"
16 * "lltc,ltm4675"
17 * "lltc,ltm4676"
18- reg: I2C slave address
19
20Optional properties:
21- regulators: A node that houses a sub-node for each regulator controlled by
22 the device. Each sub-node is identified using the node's name, with valid
23 values listed below. The content of each sub-node is defined by the
24 standard binding for regulators; see regulator.txt.
25
26Valid names of regulators depend on number of supplies supported per device:
27 * ltc2974, ltc2975 : vout0 - vout3
28 * ltc2977, ltc2980, ltm2987 : vout0 - vout7
29 * ltc2978 : vout0 - vout7
30 * ltc3880, ltc3882, ltc3886 : vout0 - vout1
31 * ltc3883 : vout0
32 * ltm4676 : vout0 - vout1

34Example:
35ltc2978@5e {
36 compatible = "lltc,ltc2978";
37 reg = <0x5e>;
38 regulators {
39 vout0 {
40 regulator-name = "FPGA-2.5V";
41 };
42 vout2 {
43 regulator-name = "FPGA-1.5V";
44 };
45 };
46};
