Its not fake, it would be something like below:

     display_panel_vdd: regulator-display-panel-vdd {
         compatible = "regulator-fixed";
         regulator-name = "display-panel-vdd";
         regulator-min-microvolt = <1100000>;
         regulator-max-microvolt = <1100000>;
         startup-delay-us = <233>;
         gpio = <&pmd8028_e1_gpios 2 GPIO_ACTIVE_HIGH>;
         enable-active-high;
         regulator-boot-on;
         pinctrl-0 = <&sde_disp0_vdd_active>;
         pinctrl-names = "default";
};
