Some platforms need a simple driver to do some controls according to typec orientation, this can be extended to be a generic driver with compatible with "typec-orientation-switch". Signed-off-by: Li Jun <jun.li@xxxxxxx> --- No changes for v5. changes on v4: - Use compatible instead of bool property for switch matching. - Change switch GPIO to be switch simple. - Change the active channel selection GPIO to be optional. previous discussion: http://patchwork.ozlabs.org/patch/1054342/ .../bindings/usb/typec-switch-simple.yaml | 69 ++++++++++++++++++++++ 1 file changed, 69 insertions(+) diff --git a/Documentation/devicetree/bindings/usb/typec-switch-simple.yaml b/Documentation/devicetree/bindings/usb/typec-switch-simple.yaml new file mode 100644 index 0000000..244162d --- /dev/null +++ b/Documentation/devicetree/bindings/usb/typec-switch-simple.yaml @@ -0,0 +1,69 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/usb/typec-switch-simple.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Typec Orientation Switch Simple Solution Bindings + +maintainers: + - Li Jun <jun.li@xxxxxxx> + +description: |- + USB SuperSpeed (SS) lanes routing to which side of typec connector is + decided by orientation, this maybe achieved by some simple control like + GPIO toggle. + +properties: + compatible: + const: typec-orientation-switch + + switch-gpios: + description: | + gpio specifier to switch the super speed active channel, + GPIO_ACTIVE_HIGH: GPIO state high for cc1; + GPIO_ACTIVE_LOW: GPIO state low for cc1. + maxItems: 1 + + port: + type: object + additionalProperties: false + description: -| + Connection to the remote endpoint using OF graph bindings that model SS + data bus to typec connector. + + properties: + endpoint: + type: object + additionalProperties: false + + properties: + remote-endpoint: true + + required: + - remote-endpoint + + required: + - endpoint + +required: + - compatible + - port + +additionalProperties: false + +examples: + - | + #include <dt-bindings/gpio/gpio.h> + ptn36043 { + compatible = "typec-orientation-switch"; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_ss_sel>; + switch-gpios = <&gpio3 15 GPIO_ACTIVE_HIGH>; + + port { + usb3_data_ss: endpoint { + remote-endpoint = <&typec_con_ss>; + }; + }; + }; -- 2.7.4
