    Subject[PATCH 2/3] regulator: tps65910: dt: support when "regulators" node found
    Date
    The device tree binding for the tps65910 is described as:
    tps65911 {
    reg = <0x2d>
    :::::::::
    regulators {
    compatible = "ti,tps65911";
    ldo1_reg: ldo1 {
    /** regulator entry */
    };

    ldo2_reg: ldo2 {
    /** regulator entry */
    };
    ::::::::::
    };
    };

    Support the regulators functionality only when there is "regulators"
    child node available for tps65910.
