dt-bindings: net: wireless: Convert ESP ESP8089 binding to a schema 



The ESP8089 Wireless Chip is supported by Linux (through an out-of-tree
driver) thanks to its device tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

Espressif ESP8089 wireless SDIO devices



This node provides properties for controlling the ESP8089 wireless device.

The node is expected to be specified as a child node to the SDIO controller

that connects the device to the system.



Required properties:



 - compatible : Should be "esp,esp8089".



Optional properties:

 - esp,crystal-26M-en: Integer value for the crystal_26M_en firmware parameter



Example:



&mmc1 {

	#address-cells = <1>;

	#size-cells = <0>;



	vmmc-supply = <&reg_dldo1>;

	mmc-pwrseq = <&wifi_pwrseq>;

	bus-width = <4>;

	non-removable;



	esp8089: sdio_wifi@1 {

		compatible = "esp,esp8089";

		reg = <1>;

		esp,crystal-26M-en = <2>;

	};

};
