Required properties:
- compatible: Must be one of the following, depending on the
model:
"microchip,mcp41010"

"microchip,mcp41100"
"microchip,mcp42010"
"microchip,mcp42050"
"microchip,mcp42100"
Example:
potentiometer@0 {
compatible = "microchip,mcp41010";
reg = <0>;
spi-max-frequency = <500000>;
};
