Convert Amlogic Meson pin controller binding to yaml. Signed-off-by: Heiner Kallweit <hkallweit1@xxxxxxxxx> --- v2: - consider that more than one compatible can be set - remove bus part from example v3: - remove minItem/maxItem properties for compatible v4: - split patch to be able to deal with the different reg/reg-names --- .../pinctrl/amlogic,meson-pinctrl-a1.yaml | 60 ++++++++++++ .../pinctrl/amlogic,meson-pinctrl-common.yaml | 53 +++++++++++ .../amlogic,meson-pinctrl-g12a-aobus.yaml | 61 ++++++++++++ .../amlogic,meson-pinctrl-g12a-periphs.yaml | 65 +++++++++++++ .../pinctrl/amlogic,meson8-pinctrl-aobus.yaml | 69 ++++++++++++++ .../pinctrl/amlogic,meson8-pinctrl-cbus.yaml | 71 ++++++++++++++ .../bindings/pinctrl/meson,pinctrl.txt | 94 ------------------- 7 files changed, 379 insertions(+), 94 deletions(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-a1.yaml create mode 100644 Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-common.yaml create mode 100644 Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-g12a-aobus.yaml create mode 100644 Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-g12a-periphs.yaml create mode 100644 Documentation/devicetree/bindings/pinctrl/amlogic,meson8-pinctrl-aobus.yaml create mode 100644 Documentation/devicetree/bindings/pinctrl/amlogic,meson8-pinctrl-cbus.yaml delete mode 100644 Documentation/devicetree/bindings/pinctrl/meson,pinctrl.txt diff --git a/Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-a1.yaml b/Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-a1.yaml new file mode 100644 index 000000000..1db9d8453 --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/amlogic,meson-pinctrl-a1.yaml @@ -0,0 +1,60 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/amlogic,meson-pinctrl-a1.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Amlogic Meson A1 pinmux controller + +maintainers: + - Neil Armstrong <neil.armstrong@xxxxxxxxxx> + +allOf: + - $ref: amlogic,meson-pinctrl-common.yaml# + +properties: + compatible: + enum: + - amlogic,meson-a1-periphs-pinctrl + - amlogic,meson-s4-periphs-pinctrl + +additionalProperties: true + +patternProperties: + "^bank@[0-9a-z]+$": + $ref: amlogic,meson-pinctrl-common.yaml#/$defs/meson-gpio + + properties: + reg: + maxItems: 2 + + reg-names: + items: + - const: mux + - const: gpio + +examples: + - | + periphs_pinctrl: pinctrl { + compatible = "amlogic,meson-a1-periphs-pinctrl";
