You can't do 200MHz with 3.3v and vqmmc-supply is fixed already at 1.8v, so here seem to be no voltage shifters involved at all? Either way, it doesn't matter to barebox. > + non-removable; > + status = "okay"; > +}; > + > +&wdog1 { > + pinctrl-names = "default"; > + pinctrl-0 = <&pinctrl_wdog>; > + fsl,ext-reset-output; > + status = "okay"; > +}; > + > +&iomuxc { > + pinctrl_i2c1: i2c1grp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C1_SCL__I2C1_SCL 0x400001c2 > + MX8MP_IOMUXC_I2C1_SDA__I2C1_SDA 0x400001c2 > + >; > + }; > + > + pinctrl_i2c1_gpio: i2c1-gpiogrp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C1_SCL__GPIO5_IO14 0x400001c2 > + MX8MP_IOMUXC_I2C1_SDA__GPIO5_IO15 0x400001c2 > + >; > + }; > + > + pinctrl_i2c2: i2c2grp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C2_SCL__I2C2_SCL 0x400001c2 > + MX8MP_IOMUXC_I2C2_SDA__I2C2_SDA 0x400001c2 > + >; > + }; > + > + pinctrl_i2c2_gpio: i2c2-gpiogrp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C2_SCL__GPIO5_IO16 0x400001c2 > + MX8MP_IOMUXC_I2C2_SDA__GPIO5_IO17 0x400001c2 > + >; > + }; > + > + pinctrl_i2c3: i2c3grp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C3_SCL__I2C3_SCL 0x400001c2 > + MX8MP_IOMUXC_I2C3_SDA__I2C3_SDA 0x400001c2 > + >; > + }; > + > + pinctrl_i2c3_gpio: i2c3-gpiogrp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C3_SCL__GPIO5_IO18 0x400001c2 > + MX8MP_IOMUXC_I2C3_SDA__GPIO5_IO19 0x400001c2 > + >; > + }; > + > + pinctrl_i2c4: i2c4grp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C4_SCL__I2C4_SCL 0x400001c2 > + MX8MP_IOMUXC_I2C4_SDA__I2C4_SDA 0x400001c2 > + >; > + }; > + > + pinctrl_i2c4_gpio: i2c4-gpiogrp { > + fsl,pins = < > + MX8MP_IOMUXC_I2C4_SCL__GPIO5_IO20 0x400001c2 > + MX8MP_IOMUXC_I2C4_SDA__GPIO5_IO21 0x400001c2 > + >; > + }; > + > + pinctrl_pmic: pmicgrp { > + fsl,pins = < > + MX8MP_IOMUXC_GPIO1_IO03__GPIO1_IO03 0x1c0 > + >; > + }; > + > + pinctrl_uart1: uart1grp { > + fsl,pins = < > + MX8MP_IOMUXC_UART1_RXD__UART1_DCE_RX 0x140 > + MX8MP_IOMUXC_UART1_TXD__UART1_DCE_TX 0x140 > + >; > + }; > + > + pinctrl_uart1_rtscts: uart1-rtsctsgrp { > + fsl,pins = < > + MX8MP_IOMUXC_UART3_TXD__UART1_DCE_RTS 0x140 > + MX8MP_IOMUXC_UART3_RXD__UART1_DCE_CTS 0x140 > + >; > + }; > + > + pinctrl_uart2: uart2grp { > + fsl,pins = < > + MX8MP_IOMUXC_UART2_RXD__UART2_DCE_RX 0x140 > + MX8MP_IOMUXC_UART2_TXD__UART2_DCE_TX 0x140 > + >; > + }; > + > + pinctrl_uart4: uart4grp { > + fsl,pins = < > + MX8MP_IOMUXC_UART4_RXD__UART4_DCE_RX 0x140 > + MX8MP_IOMUXC_UART4_TXD__UART4_DCE_TX 0x140 > + >; > + }; > + > + pinctrl_usdhc2: usdhc2grp { > + fsl,pins = < > + MX8MP_IOMUXC_SD2_CLK__USDHC2_CLK 0x190 > + MX8MP_IOMUXC_SD2_CMD__USDHC2_CMD 0x1d0 > + MX8MP_IOMUXC_SD2_DATA0__USDHC2_DATA0 0x1d0 > + MX8MP_IOMUXC_SD2_DATA1__USDHC2_DATA1 0x1d0 > + MX8MP_IOMUXC_SD2_DATA2__USDHC2_DATA2 0x1d0 > + MX8MP_IOMUXC_SD2_DATA3__USDHC2_DATA3 0x1d0 > + >; > + }; > + > + pinctrl_usdhc2_cd: usdhc2-cdgrp { > + fsl,pins = < > + MX8MP_IOMUXC_SD2_CD_B__GPIO2_IO12 0x1c0 > + >; > + }; > + > + pinctrl_usdhc3: usdhc3grp { > + fsl,pins = < > + MX8MP_IOMUXC_NAND_WE_B__USDHC3_CLK 0x190 > + MX8MP_IOMUXC_NAND_WP_B__USDHC3_CMD 0x1d0 > + MX8MP_IOMUXC_NAND_DATA04__USDHC3_DATA0 0x1d0 > + MX8MP_IOMUXC_NAND_DATA05__USDHC3_DATA1 0x1d0 > + MX8MP_IOMUXC_NAND_DATA06__USDHC3_DATA2 0x1d0 > + MX8MP_IOMUXC_NAND_DATA07__USDHC3_DATA3 0x1d0 > + MX8MP_IOMUXC_NAND_RE_B__USDHC3_DATA4 0x1d0 > + MX8MP_IOMUXC_NAND_CE2_B__USDHC3_DATA5 0x1d0 > + MX8MP_IOMUXC_NAND_CE3_B__USDHC3_DATA6 0x1d0 > + MX8MP_IOMUXC_NAND_CLE__USDHC3_DATA7 0x1d0 > + MX8MP_IOMUXC_NAND_CE1_B__USDHC3_STROBE 0x190 > + >; > + }; > + > + pinctrl_usdhc3_100mhz: usdhc3-100mhzgrp { > + fsl,pins = < > + MX8MP_IOMUXC_NAND_WE_B__USDHC3_CLK 0x194 > + MX8MP_IOMUXC_NAND_WP_B__USDHC3_CMD 0x1d4 > + MX8MP_IOMUXC_NAND_DATA04__USDHC3_DATA0 0x1d4 > + MX8MP_IOMUXC_NAND_DATA05__USDHC3_DATA1 0x1d4 > + MX8MP_IOMUXC_NAND_DATA06__USDHC3_DATA2 0x1d4 > + MX8MP_IOMUXC_NAND_DATA07__USDHC3_DATA3 0x1d4 > + MX8MP_IOMUXC_NAND_RE_B__USDHC3_DATA4 0x1d4 > + MX8MP_IOMUXC_NAND_CE2_B__USDHC3_DATA5 0x1d4 > + MX8MP_IOMUXC_NAND_CE3_B__USDHC3_DATA6 0x1d4 > + MX8MP_IOMUXC_NAND_CLE__USDHC3_DATA7 0x1d4 > + MX8MP_IOMUXC_NAND_CE1_B__USDHC3_STROBE 0x194 > + >; > + }; > + > + pinctrl_usdhc3_200mhz: usdhc3-200mhzgrp { > + fsl,pins = < > + MX8MP_IOMUXC_NAND_WE_B__USDHC3_CLK 0x196 > + MX8MP_IOMUXC_NAND_WP_B__USDHC3_CMD 0x1d6 > + MX8MP_IOMUXC_NAND_DATA04__USDHC3_DATA0 0x1d6 > + MX8MP_IOMUXC_NAND_DATA05__USDHC3_DATA1 0x1d6 > + MX8MP_IOMUXC_NAND_DATA06__USDHC3_DATA2 0x1d6 > + MX8MP_IOMUXC_NAND_DATA07__USDHC3_DATA3 0x1d6 > + MX8MP_IOMUXC_NAND_RE_B__USDHC3_DATA4 0x1d6 > + MX8MP_IOMUXC_NAND_CE2_B__USDHC3_DATA5 0x1d6 > + MX8MP_IOMUXC_NAND_CE3_B__USDHC3_DATA6 0x1d6 > + MX8MP_IOMUXC_NAND_CLE__USDHC3_DATA7 0x1d6 > + MX8MP_IOMUXC_NAND_CE1_B__USDHC3_STROBE 0x196 > + >; > + }; > + > + pinctrl_wdog: wdoggrp { > + fsl,pins = < > + MX8MP_IOMUXC_GPIO1_IO02__WDOG1_WDOG_B 0xc6 > + >; > + }; > +}; > -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
