Signed-off-by: Yinbo Zhu --- Change in v7: 1. Add all change log information. Change in v6: 1. NO change, but other patch in this series patches set has change. Change in v5: 1. Drop dependencies. 2. Add spaces after '='. 3. Replace string loongson2 with loongson-2 in title. Change in v4: 1. Replace Loongson2 with Loongson-2. Change in v3: 1. Drop the quotes in "pinctrl.yaml#". 2. Remove the items in function node. 3. Add requird node for "group" and "function" in properties. Change in v2: 1. Add "$ref to pinctrl.yaml". 2. Put required after patternProperties. 3. Add "additionalProperties: false" after '-pins$' 4. Add "unevaluatedProperties: false" after 'pinmux$' 5. Fixup the broken indentation in patternProperties node. 6. Use 4 spaces for example indentation. .../pinctrl/loongson,ls2k-pinctrl.yaml | 125 ++++++++++++++++++ MAINTAINERS | 1 + 2 files changed, 126 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/loongson,ls2k-pinctrl.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/loongson,ls2k-pinctrl.yaml b/Documentation/devicetree/bindings/pinctrl/loongson,ls2k-pinctrl.yaml new file mode 100644 index 000000000000..34683a4856ad --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/loongson,ls2k-pinctrl.yaml @@ -0,0 +1,125 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/loongson,ls2k-pinctrl.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Loongson-2 SoC Pinctrl Controller + +maintainers: + - zhanghongchen + - Yinbo Zhu + +allOf: + - $ref: pinctrl.yaml# + +properties: + compatible: + const: loongson,ls2k-pinctrl + + reg: + maxItems: 1 + +patternProperties: + '-pins$': + type: object + + additionalProperties: false + + patternProperties: + 'pinmux$': + type: object + description: node for pinctrl. + $ref: pinmux-node.yaml# + + unevaluatedProperties: false + + properties: + groups: + description: + One or more groups of pins to mux to a certain function + items: + enum: [gpio, sdio, can1, can0, pwm3, pwm2, pwm1, pwm0, i2c1, i2c0, + nand, sata_led, lio, i2s, hda, uart2, uart1, camera, dv01, + dvo0] + function: + description: + The function that a group of pins is muxed to + enum: [gpio, sdio, can1, can0, pwm3, pwm2, pwm1, pwm0, i2c1, i2c0, + nand, sata_led, lio, i2s, hda, uart2, uart1, camera, dv01, + dvo0] + + required: + - groups + - function + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + pctrl: pinctrl@1fe00420 { + compatible = "loongson,ls2k-pinctrl"; + reg = <0x1fe00420 0x18>; + sdio_pins_default: sdio-pins { + sdio-pinmux { + groups = "sdio"; + function = "sdio"; + }; + + sdio-det-pinmux { + groups = "pwm2"; + function = "gpio"; + }; + }; + + pwm1_pins_default: pwm1-pins { + pinmux { + groups = "pwm1"; + function = "pwm1"; + }; + }; + + pwm0_pins_default: pwm0-pins { + pinmux { + groups = "pwm0"; + function = "pwm0"; + }; + }; + + i2c1_pins_default: i2c1-pins { + pinmux { + groups = "i2c1"; + function = "i2c1"; + }; + }; + + i2c0_pins_default: i2c0-pins { + pinmux { + groups = "i2c0"; + function = "i2c0"; + }; + }; + + nand_pins_default: nand-pins { + pinmux { + groups = "nand"; + function = "nand"; + }; + }; + + hda_pins_default: hda-pins { + grp0-pinmux { + groups = "hda"; + function = "hda"; + }; + + grp1-pinmux { + groups = "i2s"; + function = "gpio"; + }; + }; + }; diff --git a/MAINTAINERS b/MAINTAINERS index f75464dadaaa..c9dc5ddbd9fe 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -12038,6 +12038,7 @@ M: zhanghongchen M: Yinbo Zhu L: linux-gpio@vger.kernel.org S: Maintained +F: Documentation/devicetree/bindings/pinctrl/loongson,ls2k-pinctrl.yaml F: drivers/pinctrl/pinctrl-loongson2.c LSILOGIC MPT FUSION DRIVERS (FC/SAS/SPI)
