usage of property "supply-gpios" within "jedec,spi-nor"

[B0R0b]

I am working with a flash chip which can be powered on by setting a GPIO pin to high. Everything works fine if I define the GPIO as normal Output and set the pin manually to high before executing any flash actions.
During the definition of the spi part of the dts I saw that it seems to be possible to define a property "supply-gpios" inside the "jedec,spi-nor" section.

S25FL064L: S25FL064L@0 {
	compatible = "jedec,spi-nor";
	reg = <0>;
	supply-gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>;  
	label = "S25FL064L";
	spi-max-frequency = <50000000>; 
	has-dpd;
	jedec-id = [01 60 17];
	size = <536870912>; // size in bit 64 * 1024 * 1024 * 8
};

I assigned the pin testwise without success and it seems that it is not touched by any driver. I expected the pin handling should be part of the according spi driver implemtenation as the spi-device.yaml includes power.yaml where the property is defined.

I would like to know how to use the "supply-gpios" property correctly.
