TQ EEPROM Sysinfo Driver
------------------------

This binding describes a sysinfo provider which retrieves system
identification information from an I2C EEPROM device.

Required properties:

- compatible: "tq,eeprom-sysinfo"
- nvmem-cells: phandle referencing the nvmem cell
- nvmem-cell-names: string, should be "device_info"

Example:

&i2c1 {
	eeprom@50 {
		compatible = "atmel,24c64";
		reg = <0x50>;

		nvmem-layout {
			compatible = "fixed-layout";
			#address-cells = <1>;
			#size-cells = <1>;

			module_info: module-info@20 {
				reg = <0x20 0x60>;
			};
		};
	};
};

sysinfo {
	compatible = "tq,eeprom-sysinfo";
	nvmem-cells = <&module_info>;
	nvmem-cell-names = "device_info";
};
