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 lltc,ltc2634-l12
12 lltc,ltc2634-l10
13 lltc,ltc2634-l8
14 lltc,ltc2634-h12
15 lltc,ltc2634-h10
16 lltc,ltc2634-h8
17 lltc,ltc2636-l12
18 lltc,ltc2636-l10
19 lltc,ltc2636-l8
20 lltc,ltc2636-h12
21 lltc,ltc2636-h10
22 lltc,ltc2636-h8
23
24 Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
25 apply. In particular, "reg" and "spi-max-frequency" properties must be given.
26
27 Optional properties:
28 - vref-supply: Phandle to the external reference voltage supply. This should
29 only be set if there is an external reference voltage connected to the VREF
30 pin. If the property is not set the internal reference is used.
31
32 Example:
33
34 vref: regulator-vref {
35 compatible = "regulator-fixed";
36 regulator-name = "vref-ltc2632";
37 regulator-min-microvolt = <1250000>;
38 regulator-max-microvolt = <1250000>;
39 regulator-always-on;
40 };
41
42 spi_master {
43 dac: ltc2632@0 {
44 compatible = "lltc,ltc2632-l12";
45 reg = <0>; /* CS0 */
46 spi-max-frequency = <1000000>;
47 vref-supply = <&vref>; /* optional */
48 };
49 };
