From: ChiYuan Huang <cy_huang@xxxxxxxxxxx> Add devicetree binding for Richtek RT6190 4-Switch buckboost controller. Signed-off-by: ChiYuan Huang <cy_huang@xxxxxxxxxxx> --- Hi, Rob: Since I didn't got any reply from the v2 dt-binding question. https://lore.kernel.org/lkml/CADiBU3_WUeyYdnmnG0Ff2pH+b3u1zOtP1z44LcA53Ba5c9nrEw@xxxxxxxxxxxxxx/ In v3, I aleady fixed it following by your comment. I'm just wondering the corrent usage. As I know, 'enable-gpios' comes from 'gpio-consumer-common.yaml'. In the common yaml file, it's already declared 'enable-gpios' maxItems as '1'. That's why I just declared it as 'true'. Since v3: - Fix the typo 'upply' to 'supply'. - Declare 'enable-gpios' maxItems as 1. - Declare the 'maxItems' for the property 'regulator-allowed-modes'. Since v2: - Rename binding filename to 'richtek,rt6190.yaml' --- .../bindings/regulator/richtek,rt6190.yaml | 79 ++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/richtek,rt6190.yaml diff --git a/Documentation/devicetree/bindings/regulator/richtek,rt6190.yaml b/Documentation/devicetree/bindings/regulator/richtek,rt6190.yaml new file mode 100644 index 00000000..29f7d3d --- /dev/null +++ b/Documentation/devicetree/bindings/regulator/richtek,rt6190.yaml @@ -0,0 +1,79 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/regulator/richtek,rt6190.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Richtek RT6190 4-Switch BuckBoost controller + +maintainers: + - ChiYuan Huang <cy_huang@xxxxxxxxxxx> + +description: | + The RT6190 is 4-Switch BuckBoost controller designed for converting input + voltage to output voltage that can be equal to, higher or lower than input + voltage.
