    +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";
    + };
    + };
    +};
