1* Microchip MCP3911 Dual channel analog front end (ADC)
2
3Required properties:
4 - compatible: Should be "microchip,mcp3911"
5 - reg: SPI chip select number for the device
6
7Recommended properties:
8 - spi-max-frequency: Definition as per
9	 Documentation/devicetree/bindings/spi/spi-bus.txt.
10	 Max frequency for this chip is 20MHz.
11
12Optional properties:
13 - clocks: Phandle and clock identifier for sampling clock
14 - interrupt-parent: Phandle to the parent interrupt controller
15 - interrupts: IRQ line for the ADC
16 - microchip,device-addr: Device address when multiple MCP3911 chips are present on the
17	same SPI bus. Valid values are 0-3. Defaults to 0.
18 - vref-supply: Phandle to the external reference voltage supply.

20Example:
21adc@0 {
22	compatible = "microchip,mcp3911";
23	reg = <0>;
24	interrupt-parent = <&gpio5>;
25	interrupts = <15 IRQ_TYPE_EDGE_RISING>;
26	spi-max-frequency = <20000000>;
27	microchip,device-addr = <0>;
28	vref-supply = <&vref_reg>;
29	clocks = <&xtal>;
30};
