I've read a downstream LPI-related dts and didn't find any clock-related properties. Also sc7280-lpass-lpi dt-binding doesn't have any clock-related properties. > >> + >> +patternProperties: >> + "-state$": >> + oneOf: >> + - $ref: "#/$defs/qcom-sdm660-lpass-state" >> + - patternProperties: >> + "-pins$": >> + $ref: "#/$defs/qcom-sdm660-lpass-state" >> + additionalProperties: false >> + >> +$defs: >> + qcom-sdm660-lpass-state: >> + type: object >> + description: >> + Pinctrl node's client devices use subnodes for desired pin configuration. >> + Client device subnodes use below standard properties. >> + $ref: qcom,lpass-lpi-common.yaml#/$defs/qcom-tlmm-state >> + unevaluatedProperties: false >> + >> + properties: >> + pins: >> + description: >> + List of gpio pins affected by the properties specified in this >> + subnode. >> + items: >> + pattern: "^gpio([0-9]|[1-2][0-9]|3[0-1])$" >> + >> + function: >> + enum: [ gpio, comp_rx, dmic12, dmic34, mclk0, pdm_2_gpios, >> + pdm_clk, pdm_rx, pdm_sync ] >> + description: >> + Specify the alternative function to be configured for the specified >> + pins. >> + >> +allOf: >> + - $ref: qcom,lpass-lpi-common.yaml# >> + >> +required: >> + - compatible >> + - reg >> + >> +unevaluatedProperties: false >> + >> +examples: >> + - | >> + lpi_tlmm: pinctrl@15070000 { >> + compatible = "qcom,sdm660-lpass-lpi-pinctrl"; >> + reg = <0x15070000 0x20000>; >> + gpio-controller; >> + #gpio-cells = <2>; >> + gpio-ranges = <&lpi_tlmm 0 0 32>; > That's quite incomplete example.
