dt-bindings:iio:potentiometer:microchip,mcp41010 txt to yaml conversion
A simple binding that I almost just move to trivial devices. The small amount of additional documentation and relatively large number of compatible entries convinced me to suggest we keep this one separately documented.

-* Microchip MCP41010/41050/41100/42010/42050/42100 Digital Potentiometer
-
-Datasheet publicly available at:
-https://ww1.microchip.com/downloads/en/devicedoc/11195c.pdf
-
-The node for this driver must be a child node of a SPI controller, hence
-all mandatory properties described in
-
- Documentation/devicetree/bindings/spi/spi-bus.txt
-
-must be specified.
-
-Required properties:
- - compatible: Must be one of the following, depending on the
- model:
- "microchip,mcp41010"
- "microchip,mcp41050"
- "microchip,mcp41100"
- "microchip,mcp42010"
- "microchip,mcp42050"
- "microchip,mcp42100"
-
-Example:
-potentiometer@0 {
- compatible = "microchip,mcp41010";
- reg = <0>;
- spi-max-frequency = <500000>;
-};
