Reviewed-by: Krzysztof Kozlowski Co-developed-by: Alina Yu Signed-off-by: Alina Yu Signed-off-by: ChiYuan Huang --- Since v3 - Move unevaluatedProperties line after $ref for binding patch. - Add Reviewed-by tag for binding patch. Since v2 - Remove the properties for interrupt controller things in the binding documentation. - Fix dtc error for typo, it's 'regulator-name', not 'regulator-compatible'. - Add regulator min/max microamp to allow otg vbus current adjustable in example. - Specify the active-level for charge-enable-gpios in binding example. --- .../bindings/power/supply/richtek,rt9471.yaml | 73 ++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 Documentation/devicetree/bindings/power/supply/richtek,rt9471.yaml diff --git a/Documentation/devicetree/bindings/power/supply/richtek,rt9471.yaml b/Documentation/devicetree/bindings/power/supply/richtek,rt9471.yaml new file mode 100644 index 00000000..fbb54cf --- /dev/null +++ b/Documentation/devicetree/bindings/power/supply/richtek,rt9471.yaml @@ -0,0 +1,73 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/power/supply/richtek,rt9471.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Richtek RT9471 3A Single Cell Switching Battery charger + +maintainers: + - Alina Yu + - ChiYuan Huang + +description: | + RT9471 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for + portable applications.
