* Linear Technology Micropower octal 8-Bit and 10-Bit DACs
Required properties:
- compatible: Must be one of the following:
"lltc,ltc1660"
"lltc,ltc1665"
- reg: SPI chip select number for the device
- vref-supply: Phandle to the voltage reference supply
Recommended properties:
- spi-max-frequency: Definition as per
Documentation/devicetree/bindings/spi/spi-bus.txt.
Max frequency for this chip is 5 MHz.
Example:
dac@0 {
compatible = "lltc,ltc1660";
reg = <0>;
spi-max-frequency = <5000000>;
vref-supply = <&vref_reg>;
};
