-Linear Technology LTC2632/2634/2636 DAC
-
-Required properties:
- - compatible: Has to contain one of the following:
- lltc,ltc2632-l12
- lltc,ltc2632-l10
- lltc,ltc2632-l8
- lltc,ltc2632-h12
- lltc,ltc2632-h10
- lltc,ltc2632-h8
- lltc,ltc2634-l12
- lltc,ltc2634-l10
- lltc,ltc2634-l8
- lltc,ltc2634-h12
- lltc,ltc2634-h10
- lltc,ltc2634-h8
- lltc,ltc2636-l12
- lltc,ltc2636-l10
- lltc,ltc2636-l8
- lltc,ltc2636-h12
- lltc,ltc2636-h10
- lltc,ltc2636-h8
-
-Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
-apply. In particular, "reg" and "spi-max-frequency" properties must be given.
-
-Optional properties:
- - vref-supply: Phandle to the external reference voltage supply. This should
- only be set if there is an external reference voltage connected to the VREF
- pin. If the property is not set the internal reference is used.
-
-Example:
-
- vref: regulator-vref {
- compatible = "regulator-fixed";
- regulator-name = "vref-ltc2632";
- regulator-min-microvolt = <1250000>;
- regulator-max-microvolt = <1250000>;
- regulator-always-on;
- };
-
- spi_master {
- dac: ltc2632@0 {
- compatible = "lltc,ltc2632-l12";
- reg = <0>; /* CS0 */
- spi-max-frequency = <1000000>;
- vref-supply = <&vref>; /* optional */
- };
- };
