1 Versatile Express voltage regulators
2 ------------------------------------
3
4 Requires node properties:
5 - "compatible" value: "arm,vexpress-volt"
6 - "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
7   (see Documentation/devicetree/bindings/arm/vexpress-sysreg.txt
8   for more details)
9
10 Required regulator properties:
11 - "regulator-name"
12 - "regulator-always-on"
13
14 Optional regulator properties:
15 - "regulator-min-microvolt"
16 - "regulator-max-microvolt"
17
18 See Documentation/devicetree/bindings/regulator/regulator.txt
19 for more details about the regulator properties.
20
21 When no "regulator-[min|max]-microvolt" properties are defined,
22 the device is treated as fixed (or rather "read-only") regulator.

24 Example:
25         volt@0 {
26                 compatible = "arm,vexpress-volt";
27                 arm,vexpress-sysreg,func = <2 0>;
28                 regulator-name = "Cores";
29                 regulator-min-microvolt = <800000>;
30                 regulator-max-microvolt = <1050000>;
31                 regulator-always-on;
32         };
