Maybe you should split out the three pins in: - usb_pins_cfa10056 - mac0_pins_cfa10056 - move the last one in spi2_pins_cfa10056 > + > + hog_pins_cfa10056_pullup: hog-10056-pullup@0 { > + reg = <0>; > + fsl,pinmux-ids = < > + 0x31e3 /* MX28_PAD_LCD_RESET__GPIO_3_30 */ > + >; > + fsl,drive-strength = <0>; > + fsl,voltage = <1>; > + fsl,pull-up = <1>; > + }; You could probably rename it to lcdif_pins_cfa10056_pullups or something then, and make the lcdif driver grab these pins. > + > + spi2_pins_cfa10056: spi2-cfa10056@0 { > + reg = <0>; > + fsl,pinmux-ids = < > + 0x2103 /* MX28_PAD_SSP2_SCK__GPIO_2_16 */ > + 0x2113 /* MX28_PAD_SSP2_CMD__GPIO_2_17 */ > + 0x2123 /* MX28_PAD_SSP2_D0__GPIO_2_18 */ > + >; > + fsl,drive-strength = <1>; > + fsl,voltage = <1>; > + fsl,pull-up = <1>; > + }; > + > + lcdif_pins_cfa10056: lcdif-evk@0 { > + reg = <0>; > + fsl,pinmux-ids = < > + 0x1181 /* MX28_PAD_LCD_RD_E__LCD_VSYNC */ > + 0x1191 /* MX28_PAD_LCD_WR_RWN__LCD_HSYNC */ > + 0x11a1 /* MX28_PAD_LCD_RS__LCD_DOTCLK */ > + 0x11b1 /* MX28_PAD_LCD_CS__LCD_ENABLE */ > + >; > + fsl,drive-strength = <0>; > + fsl,voltage = <1>; > + fsl,pull-up = <0>; > + }; > + }; > + > + lcdif@80030000 { > + pinctrl-names = "default"; > + pinctrl-0 = <&lcdif_24bit_pins_a > + &lcdif_pins_cfa10056>; > + display = <&display>; > + status = "okay"; > + > + display: display { > + bits-per-pixel = <32>; > + bus-width = <24>; > + > + display-timings { > + native-mode = <&timing0>; > + timing0: timing0 { > + clock-frequency = <32000000>; > + hactive = <480>; > + vactive = <800>; > + hback-porch = <2>; > + hfront-porch = <2>; > + vback-porch = <2>; > + vfront-porch = <2>; > + hsync-len = <5>; > + vsync-len = <5>; > + hsync-active = <0>; > + vsync-active = <0>; > + de-active = <1>; > + pixelclk-active = <1>; > + }; > + }; > + }; > + }; > + }; > + > + apbx@80040000 { > + usbphy1: usbphy@8007e000 { > + status = "okay"; > + }; > + }; > + }; > + > + ahb@80080000 { > + usb1: usb@80090000 { > + vbus-supply = <®_usb1_vbus>; > + pinctrl-0 = <&usbphy1_pins_a>; > + pinctrl-names = "default"; > + status = "okay"; > + }; > + }; > + > + regulators { > + compatible = "simple-bus"; > + > + reg_usb1_vbus: usb1_vbus { > + compatible = "regulator-fixed"; > + regulator-name = "usb1_vbus"; > + regulator-min-microvolt = <5000000>; > + regulator-max-microvolt = <5000000>; > + gpio = <&gpio0 7 1>; > + }; > + }; > + > + ahb@80080000 { > + mac0: ethernet@800f0000 { > + phy-mode = "rmii"; > + pinctrl-names = "default"; > + pinctrl-0 = <&mac0_pins_a>; > + phy-reset-gpios = <&gpio2 21 0>; > + phy-reset-duration = <100>; > + status = "okay"; > + }; > + }; > + > + spi2 { > + compatible = "spi-gpio"; > + pinctrl-names = "default"; > + pinctrl-0 = <&spi2_pins_cfa10056>; > + status = "okay"; > + gpio-sck = <&gpio2 16 0>; > + gpio-mosi = <&gpio2 17 0>; > + gpio-miso = <&gpio2 18 0>; > + cs-gpios = <&gpio3 5 0>; > + num-chipselects = <1>; > + #address-cells = <1>; > + #size-cells = <0>; > + > + hx8369: hx8369@0 { > + compatible = "himax,hx8369a", "himax,hx8369"; > + reg = <0>; > + spi-max-frequency = <100000>; > + spi-cpol; > + spi-cpha; > + gpios-reset = <&gpio3 30 0>; > + }; > + }; > +}; > -- > 1.8.1.2 >
