   3 Required properties:
   4  - compatible: Has to contain one of the following:
   5         lltc,ltc2632-l12
   6         lltc,ltc2632-l10
   7         lltc,ltc2632-l8
   8         lltc,ltc2632-h12
   9         lltc,ltc2632-h10
  10         lltc,ltc2632-h8
  11
  12 Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
  13 apply. In particular, "reg" and "spi-max-frequency" properties must be given.
  14
  15 Optional properties:
  16         - vref-supply: Phandle to the external reference voltage supply. This should
  17           only be set if there is an external reference voltage connected to the VREF
  18           pin. If the property is not set the internal reference is used.

  20 Example:
  21
  22         vref: regulator-vref {
  23                 compatible = "regulator-fixed";
  24                 regulator-name = "vref-ltc2632";
  25                 regulator-min-microvolt = <1250000>;
  26                 regulator-max-microvolt = <1250000>;
  27                 regulator-always-on;
  28         };

  30         spi_master {
  31                 dac: ltc2632@0 {
  32                         compatible = "lltc,ltc2632-l12";
  33                         reg = <0>; /* CS0 */
  34                         spi-max-frequency = <1000000>;
  35                         vref-supply = <&vref>; /* optional */
  36                 };
