Add DT binding documentation for cros-ec-regulator, a voltage regulator controlled by ChromeOS EC. Signed-off-by: Pi-Hsun Shih <pihsun@xxxxxxxxxxxx> --- Changes from v4: * Change compatible name from regulator-cros-ec to cros-ec-regulator. Changes from v3: * Fix dt bindings file name. * Add full example. Changes from v2: * No change Changes from v1: * Change compatible string to google,regulator-cros-ec. * Use reg property in device tree. * Change license for dt binding according to checkpatch.pl. --- .../regulator/google,cros-ec-regulator.yaml | 51 +++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/google,cros-ec-regulator.yaml diff --git a/Documentation/devicetree/bindings/regulator/google,cros-ec-regulator.yaml b/Documentation/devicetree/bindings/regulator/google,cros-ec-regulator.yaml new file mode 100644 index 000000000000..c9453d7ce227 --- /dev/null +++ b/Documentation/devicetree/bindings/regulator/google,cros-ec-regulator.yaml @@ -0,0 +1,51 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/regulator/google,cros-ec-regulator.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ChromeOS EC controlled voltage regulators + +maintainers: + - Pi-Hsun Shih <pihsun@xxxxxxxxxxxx> + +description: + Any property defined as part of the core regulator binding, defined in + regulator.yaml, can also be used. + +allOf: + - $ref: "regulator.yaml#" + +properties: + compatible: + const: google,cros-ec-regulator + + reg: + maxItems: 1 + description: Identifier for the voltage regulator to ChromeOS EC. + +required: + - compatible + - reg + +examples: + - | + spi0 { + #address-cells = <1>; + #size-cells = <0>; + + cros_ec: ec@0 { + compatible = "google,cros-ec-spi"; + reg = <0>; + #address-cells = <1>; + #size-cells = <0>; + + regulator@0 { + compatible = "google,cros-ec-regulator"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <3300000>; + reg = <0>; + }; + }; + }; +... -- 2.27.0.278.ge193c7cf3a9-goog
