1 Analog Devices AD7303 DAC device driver
2
3 Required properties:
4         - compatible: Must be "adi,ad7303"
5         - reg: SPI chip select number for the device
6         - spi-max-frequency: Max SPI frequency to use (< 30000000)
7         - Vdd-supply: Phandle to the Vdd power supply
8
9 Optional properties:
10         - REF-supply: Phandle to the external reference voltage supply. This should
11           only be set if there is an external reference voltage connected to the REF
12           pin. If the property is not set Vdd/2 is used as the reference voltage.
