-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 */
-};
