mcp3021 properties



Required properties:

- compatible: Must be one of the following:

	- "microchip,mcp3021" for mcp3021

	- "microchip,mcp3221" for mcp3221

- reg: I2C address



Optional properties:



- reference-voltage-microvolt

	Reference voltage in microvolt (uV)



Example:



mcp3021@4d {

	compatible = "microchip,mcp3021";

	reg = <0x4d>;



	reference-voltage-microvolt = <4500000>; /* 4.5 V */

};
