Are all these buses so slow? Why not 400000? Also 100000 is the default anyway. > + > + gpio { > + pinctrl_gpio: gpiogrp { > + fsl,pins = < > + MX6QDL_PAD_ENET_CRS_DV__GPIO1_IO25 0x1b0b0 /* led enable */ > + MX6QDL_PAD_EIM_BCLK__GPIO6_IO31 0x1b0b0 /* backlight enable */ > + MX6QDL_PAD_NANDF_CS2__GPIO6_IO15 0x1b0b0 /* LCD power enable */ > + MX6QDL_PAD_NANDF_CS3__GPIO6_IO16 0x1b0b0 /* led yellow */ > + MX6QDL_PAD_EIM_EB0__GPIO2_IO28 0x1b0b0 /* led red */ > + MX6QDL_PAD_EIM_A24__GPIO5_IO04 0x1b0b0 /* led green */ > + MX6QDL_PAD_EIM_EB1__GPIO2_IO29 0x1b0b0 /* led blue */ > + MX6QDL_PAD_SD3_DAT5__GPIO7_IO00 0x1b0b0 /* Profibus IRQ */ > + MX6QDL_PAD_SD3_DAT6__GPIO6_IO18 0x1b0b0 /* FPGA IRQ */ > + MX6QDL_PAD_EIM_A23__GPIO6_IO06 0x1b0b0 /* spi bus #2 SS driver enable */ > + MX6QDL_PAD_GPIO_18__GPIO7_IO13 0x1b0b0 /* RST_LOC# PHY reset input (has pull-down!)*/ > + MX6QDL_PAD_ENET_RX_ER__USB_OTG_ID 0x1b0b0 /* USB_OTG_ID = GPIO1_24*/ > + MX6QDL_PAD_SD3_RST__GPIO7_IO08 0x1b0b0 /* SD2 level shifter output enable */ > + MX6QDL_PAD_ENET_RXD0__GPIO1_IO27 0x1b0b0 /* SD1 card detect input */ > + MX6QDL_PAD_DI0_PIN4__GPIO4_IO20 0x1b0b0 /* SD1 write protect input */ > + MX6QDL_PAD_GPIO_19__GPIO4_IO05 0x1b0b0 /* SD2 card detect input */ > + MX6QDL_PAD_SD4_DAT2__GPIO2_IO10 0x1b0b0 /* SD2 write protect input */ Shouldn't the SD specific pins in the usdhc nodes below? Also backlight enable, LEDs could also be moved to the corresponding device nodes. > + MX6QDL_PAD_SD4_DAT1__GPIO2_IO09 0x1b0b0 /* Touchscreen IRQ */ > + MX6QDL_PAD_EIM_A22__GPIO2_IO16 0x1b0b0 /* PCIe reset */ > + >; > + }; > + }; > + > + gpmi-nand { > + pinctrl_gpmi_nand: gpmi-nand { > + fsl,pins = < > + MX6QDL_PAD_NANDF_CLE__NAND_CLE 0xb0b1 > + MX6QDL_PAD_NANDF_ALE__NAND_ALE 0xb0b1 > + MX6QDL_PAD_NANDF_WP_B__NAND_WP_B 0xb0b1 > + MX6QDL_PAD_NANDF_RB0__NAND_READY_B 0xb000 > + MX6QDL_PAD_NANDF_CS0__NAND_CE0_B 0xb0b1 > + MX6QDL_PAD_SD4_CMD__NAND_RE_B 0xb0b1 > + MX6QDL_PAD_SD4_CLK__NAND_WE_B 0xb0b1 > + MX6QDL_PAD_NANDF_D0__NAND_DATA00 0xb0b1 > + MX6QDL_PAD_NANDF_D1__NAND_DATA01 0xb0b1 > + MX6QDL_PAD_NANDF_D2__NAND_DATA02 0xb0b1 > + MX6QDL_PAD_NANDF_D3__NAND_DATA03 0xb0b1 > + MX6QDL_PAD_NANDF_D4__NAND_DATA04 0xb0b1 > + MX6QDL_PAD_NANDF_D5__NAND_DATA05 0xb0b1 > + MX6QDL_PAD_NANDF_D6__NAND_DATA06 0xb0b1 > + MX6QDL_PAD_NANDF_D7__NAND_DATA07 0xb0b1 > + >; > + }; > + }; > + > + i2c1 { > + pinctrl_i2c1: i2c1grp { > + fsl,pins = < > + MX6QDL_PAD_CSI0_DAT8__I2C1_SDA 0x4001b8b1 > + MX6QDL_PAD_CSI0_DAT9__I2C1_SCL 0x4001b8b1 > + >; > + }; > + }; > + > + i2c2 { > + pinctrl_i2c2: i2c2grp { > + fsl,pins = < > + MX6QDL_PAD_KEY_COL3__I2C2_SCL 0x4001b8b1 > + MX6QDL_PAD_KEY_ROW3__I2C2_SDA 0x4001b8b1 > + >; > + }; > + }; > + > + i2c3 { > + pinctrl_i2c3: i2c3grp { > + fsl,pins = < > + MX6QDL_PAD_GPIO_5__I2C3_SCL 0x4001b8b1 > + MX6QDL_PAD_GPIO_6__I2C3_SDA 0x4001b8b1 > + >; Please check the indentation here and in some other pinctrl nodes.
