NOTE: The use of the compatibles with no vendor prefix
is deprecated and only listed because old DT use them.

- spi-cpha, spi-cpol (boolean):
Either SPI mode (0,0) or (1,1) must be used, so specify
none or both of spi-cpha, spi-cpol. The MCP3550/1/3
is more efficient in mode (1,1) as only 3 instead of
4 bytes need to be read from the ADC, but not all SPI
masters support it.

- vref-supply: Phandle to the external reference voltage supply.

spi_controller {
mcp3x0x@0 {
compatible = "mcp3002";
reg = <0>;
spi-max-frequency = <1000000>;
vref-supply = <&vref_reg>;

Maxim Integrated DS4422/DS4424 7-bit Sink/Source Current DAC Device Driver

Required properties:
- compatible: Should be one of
maxim,ds4422

- reg: Should contain the DAC I2C address

Optional properties:
- vcc-supply: Power supply is optional. If not defined, driver will ignore it.

Example:

compatible = "maxim,ds4424";
reg = <0x10>; /* When A0, A1 pins are ground */
vcc-supply = <&vcc_3v3>;
