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.
