Enable Regulator using GPIO


I want to use GPIO to enable regulator in device tree as shown below.

gpio_reg: gpio_reg {
compatible = "regulator-fixed"
regulator-name = "gpio_reg";
gpio = <&tlmm_pinmux 23 0>;
regulator-min-microvolt = <1800000>;
regulatot-max-microvolt = <1800000>;
status = "ok"
but i dont see any GPIO toggling happening on gpio23.

if i use gpio directly from sysfs without using in device tree i can see gpio toggling.

Is something i am missing to specify in device tree to enable regulator?
