Add pinctrl and gpio bindings for Actions Semi S500 SoC. Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxx> --- Changes in v2: - Added myself to the list of maintainers, per Mani's suggestion - Added a description item for each of the four register ranges, per Rob's feedback - Renamed the pin nodes and got rid of the if/then hack in the patternProperties,according to Rob's suggestion - Added a missing 'additionalProperties: false' line - Updated the example with the new node names and the split register range .../pinctrl/actions,s500-pinctrl.yaml | 240 ++++++++++++++++++ 1 file changed, 240 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/actions,s500-pinctrl.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/actions,s500-pinctrl.yaml b/Documentation/devicetree/bindings/pinctrl/actions,s500-pinctrl.yaml new file mode 100644 index 000000000000..33391d30c00c --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/actions,s500-pinctrl.yaml @@ -0,0 +1,240 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/actions,s500-pinctrl.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Actions Semi S500 SoC pinmux & GPIO controller + +maintainers: + - Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx> + - Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxx> + +description: | + Pinmux & GPIO controller manages pin multiplexing & configuration including + GPIO function selection & GPIO attributes configuration.
