regulator: tps65910: dt: support when "regulators" node found
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.
