Signed-off-by: Tzuyi Chang --- v3 to v4 change: 1. Arrange the compatible list in alphanumerical order. v2 to v3 change: 1. Remove generic compatible and use SoC-specific compatible instead. v1 to v2 change: 1. Add description for DHC RTD SoCs. 2. Revise the compatible names. 3. Add descriptions for reg and interrupts properties. --- .../bindings/gpio/realtek,rtd-gpio.yaml | 69 +++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/realtek,rtd-gpio.yaml diff --git a/Documentation/devicetree/bindings/gpio/realtek,rtd-gpio.yaml b/Documentation/devicetree/bindings/gpio/realtek,rtd-gpio.yaml new file mode 100644 index 000000000000..dd768db37a98 --- /dev/null +++ b/Documentation/devicetree/bindings/gpio/realtek,rtd-gpio.yaml @@ -0,0 +1,69 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +# Copyright 2023 Realtek Semiconductor Corporation +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/gpio/realtek,rtd-gpio.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Realtek DHC GPIO controller + +maintainers: + - Tzuyi Chang + +description: + The GPIO controller is designed for the Realtek DHC (Digital Home Center) + RTD series SoC family, which are high-definition media processor SoCs. + +properties: + compatible: + enum: + - realtek,rtd1295-misc-gpio + - realtek,rtd1295-iso-gpio + - realtek,rtd1315e-iso-gpio + - realtek,rtd1319-iso-gpio + - realtek,rtd1319d-iso-gpio + - realtek,rtd1395-iso-gpio + - realtek,rtd1619-iso-gpio + - realtek,rtd1619b-iso-gpio + + reg: + items: + - description: GPIO controller registers + - description: GPIO interrupt registers + + interrupts: + items: + - description: Interrupt number of the assert GPIO interrupt, which is + triggered when there is a rising edge. + - description: Interrupt number of the deassert GPIO interrupt, which is + triggered when there is a falling edge. + + gpio-ranges: true + + gpio-controller: true + + "#gpio-cells": + const: 2 + +required: + - compatible + - reg + - interrupts + - gpio-ranges + - gpio-controller + - "#gpio-cells" + +additionalProperties: false + +examples: + - | + gpio@100 { + compatible = "realtek,rtd1319d-iso-gpio"; + reg = <0x100 0x100>, + <0x0 0xb0>; + interrupt-parent = <&iso_irq_mux>; + interrupts = <19>, <20>; + gpio-ranges = <&pinctrl 0 0 82>; + gpio-controller; + #gpio-cells = <2>; + };
