+
+Required properties:
+ - compatible: one of: ltc2974, ltc2977, ltc2978, ltc3880, ltc3883, ltm4676
+ - reg: I2C address
+
+Optional properties:
+ Name of the optional regulator subnode must be "regulators".
+ - #address-cells must be 1.
+ - #size-cells must be 0.
+
+ For each regulator:
+ - reg: regulator number
+ - regulator-compatible: must be vout_en<regulator number> such as vout_en3
+ valid range is:
+ ltc2977, ltc2978 : vout_en0 - vout_en7
+ ltc2974 : vout_en0 - vout_en3
+ ltc3880, ltm4676 : vout_en0 - vout_en1
+ ltc3883 : vout_en0 only
+ - regulator-name: arbitrary name for regulator
+
+Example:
+ltc2978@5e {
+ compatible = "ltc2978";
+ reg = <0x5e>;
+ regulators {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ vdacp0_reg: regulator@0 {
+ reg = <0>;
+ regulator-compatible = "vout_en0";
+ regulator-name = "FPGA-2.5V";
+ };
+ vdacp2_reg: regulator@2 {
+ reg = <2>;
+ regulator-compatible = "vout_en2";
+ regulator-name = "FPGA-1.5V";
+ };
+ };
+};
