It's in the vendor dts I have and it's likely there because marvell,armada-37xx-pinctrl.txt has the same syscon and simple-mfd compatibles. Looking at how this is used I think it's more like the older mvebu pinctrl devices. I'll remove these two compatibles and update the dtsi file. > > blank line needed here. > >> + reg: >> + maxItems: 1 >> + >> +patternProperties: >> + '-pins$': >> + type: object >> + $ref: pinmux-node.yaml# >> + >> + properties: >> + marvell,function: >> + $ref: "/schemas/types.yaml#/definitions/string" >> + description: >> + Indicates the function to select. >> + enum: [ gpio, i2c0, i2c1, nand, sdio, spi0, spi1, uart0, uart1, uart2, uart3 ] >> + >> + marvell,pins: >> + $ref: /schemas/types.yaml#/definitions/string-array >> + description: >> + Array of MPP pins to be used for the given function. >> + minItems: 1 >> + items: >> + enum: [ mpp0, mpp1, mpp2, mpp3, mpp4, mpp5, mpp6, mpp7, mpp8, mpp9, >> + mpp10, mpp11, mpp12, mpp13, mpp14, mpp15, mpp16, mpp17, mpp18, mpp19, >> + mpp20, mpp21, mpp22, mpp23, mpp24, mpp25, mpp26, mpp27, mpp28, mpp29, >> + mpp30, mpp31, mpp32, mpp33, mpp34, mpp35, mpp36, mpp37, mpp38, mpp39, >> + mpp40, mpp41, mpp42, mpp43, mpp44, mpp45 ] >> + >> +allOf: >> + - $ref: "pinctrl.yaml#" >> + >> +required: >> + - compatible >> + - reg >> + >> +additionalProperties: false >> + >> +examples: >> + - | >> + pinctrl@80020100 { >> + compatible = "marvell,ac5-pinctrl", >> + "syscon", "simple-mfd"; >> + reg = <0x80020100 0x20>; >> + >> + i2c0_pins: i2c0-pins { >> + marvell,pins = "mpp26", "mpp27"; >> + marvell,function = "i2c0"; >> + }; >> + >> + i2c0_gpio: i2c0-gpio-pins { >> + marvell,pins = "mpp26", "mpp27"; >> + marvell,function = "gpio"; >> + }; >> + }; >> -- >> 2.35.1 >> >>
