| 2 | ------------------------------------ |

| 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-config.yaml |
| 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. |
| 23 | |
| 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 | }; |
