* 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>; };
