1 * Microchip MCP3911 Dual channel analog front end (ADC)
4 - compatible: Should be "microchip,mcp3911"
5 - reg: SPI chip select number for the device
7 Recommended properties:
8 - spi-max-frequency: Definition as per
9 Documentation/devicetree/bindings/spi/spi-bus.txt.
10 Max frequency for this chip is 20MHz.
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.
