Add a device tree binding document for GPIO controlled rfkill switches. The label and radio-type properties correspond to the name and type properties used for ACPI, respectively. The shutdown-gpios property is the same as defined for ACPI. Signed-off-by: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> --- Changes since v1: - Drop quotes from $id and $schema (Krzysztof) - Use generic label property (Rob, Krzysztof) - Rename type property to radio-type (Rob) - Reorder list of radio types alphabetically (Krzysztof) - Drop reset-gpios property (Rob, Krzysztof) - Use generic node name in example (Rob, Krzysztof) --- .../devicetree/bindings/net/rfkill-gpio.yaml | 51 ++++++++++++++++++++++ 1 file changed, 51 insertions(+) diff --git a/Documentation/devicetree/bindings/net/rfkill-gpio.yaml b/Documentation/devicetree/bindings/net/rfkill-gpio.yaml new file mode 100644 index 000000000000..9630c8466fac --- /dev/null +++ b/Documentation/devicetree/bindings/net/rfkill-gpio.yaml @@ -0,0 +1,51 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/rfkill-gpio.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: GPIO controlled rfkill switch + +maintainers: + - Johannes Berg <johannes@xxxxxxxxxxxxxxxx> + - Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> + +properties: + compatible: + const: rfkill-gpio + + label: + description: rfkill switch name, defaults to node name + + radio-type: + description: rfkill radio type + enum: + - bluetooth + - fm + - gps + - nfc + - ultrawideband + - wimax + - wlan + - wwan + + shutdown-gpios: + maxItems: 1 + +required: + - compatible + - radio-type + - shutdown-gpios + +additionalProperties: false + +examples: + - | + #include <dt-bindings/gpio/gpio.h> + + rfkill { + compatible = "rfkill-gpio"; + label = "rfkill-pcie-wlan"; + radio-type = "wlan"; + shutdown-gpios = <&gpio2 25 GPIO_ACTIVE_HIGH>; + }; -- 2.30.2
