From: Giulio Benetti <giulio.benetti@benettiengineering.com> The NXP i.MXRT1050 Evaluation Kit (EVK) provides a platform for rapid evaluation of the i.MXRT, which features NXP's implementation of the Arm Cortex-M7 core. The EVK provides 32 MB SDRAM, 64 MB Quad SPI flash, Micro SD card socket, USB 2.0 OTG. This patch aims to support the preliminary booting up features as follows: GPIO LPUART SD/MMC Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com> Signed-off-by: Jesse Taube <redacted> [Jesse: Add clock-parents, edma, usdhc, anatop, remove old pinctl] --- V1->V2: * dtsi: Add clock parent definitions * dtsi: Change hex values to lowercase * dtsi: Move anatop definition from driver * dts: Remove unused pin controll (semc) * dts: Use moved pin controll header * Move aliases from dtsi to dts * Change commit description * Change licence to "GPL-2.0+ OR MIT" V2->V3: * Remove bootargs, comments, unused container * Remove unnecessary new lines * Rename imxrt to imxrt1050 for seiral and mmc * GPT uses own clock * fix memory@0 * Change GPT compatible handles --- arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/imxrt1050-evk.dts | 72 ++++++++++++ arch/arm/boot/dts/imxrt1050.dtsi | 165 ++++++++++++++++++++++++++++ 3 files changed, 239 insertions(+) create mode 100644 arch/arm/boot/dts/imxrt1050-evk.dts create mode 100644 arch/arm/boot/dts/imxrt1050.dtsidiff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 8a2dfdf01ce3..d539bf7daa86 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile@@ -723,6 +723,8 @@ dtb-$(CONFIG_SOC_IMX7D) += \ dtb-$(CONFIG_SOC_IMX7ULP) += \ imx7ulp-com.dtb \ imx7ulp-evk.dtb +dtb-$(CONFIG_SOC_IMXRT) += \ + imxrt1050-evk.dtb dtb-$(CONFIG_SOC_LS1021A) += \ ls1021a-moxa-uc-8410a.dtb \ ls1021a-qds.dtb \diff --git a/arch/arm/boot/dts/imxrt1050-evk.dts b/arch/arm/boot/dts/imxrt1050-evk.dts new file mode 100644 index 000000000000..6a9c10decf52 --- /dev/null +++ b/arch/arm/boot/dts/imxrt1050-evk.dts@@ -0,0 +1,72 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (C) 2019 + * Author(s): Giulio Benetti <giulio.benetti@benettiengineering.com> + */ + +/dts-v1/; +#include "imxrt1050.dtsi" +#include "imxrt1050-pinfunc.h" + +/ { + model = "NXP IMXRT1050-evk board"; + compatible = "fsl,imxrt1050-evk", "fsl,imxrt1050"; + + chosen { + stdout-path = &lpuart1; + }; + + aliases { + gpio0 = &gpio1; + gpio1 = &gpio2; + gpio2 = &gpio3; + gpio3 = &gpio4; + gpio4 = &gpio5; + mmc0 = &usdhc1; + serial0 = &lpuart1; + }; + + memory@80000000 { + device_type = "memory"; + reg = <0x80000000 0x2000000>; + }; +}; + +&lpuart1 { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_lpuart1>; + status = "okay"; +}; + +&iomuxc { + pinctrl-names = "default"; + pinctrl_lpuart1: lpuart1grp { + fsl,pins = < + MXRT1050_IOMUXC_GPIO_AD_B0_12_LPUART1_TXD 0xf1 + MXRT1050_IOMUXC_GPIO_AD_B0_13_LPUART1_RXD 0xf1 + >; + }; + + pinctrl_usdhc0: usdhc0grp { + fsl,pins = < + MXRT1050_IOMUXC_GPIO_B1_12_USDHC1_CD_B 0x1B000 + MXRT1050_IOMUXC_GPIO_B1_14_USDHC1_VSELECT 0xB069 + MXRT1050_IOMUXC_GPIO_SD_B0_00_USDHC1_CMD 0x17061 + MXRT1050_IOMUXC_GPIO_SD_B0_01_USDHC1_CLK 0x17061 + MXRT1050_IOMUXC_GPIO_SD_B0_05_USDHC1_DATA3 0x17061 + MXRT1050_IOMUXC_GPIO_SD_B0_04_USDHC1_DATA2 0x17061 + MXRT1050_IOMUXC_GPIO_SD_B0_03_USDHC1_DATA1 0x17061 + MXRT1050_IOMUXC_GPIO_SD_B0_02_USDHC1_DATA0 0x17061 + >; + }; +}; + +&usdhc1 { + pinctrl-names = "default", "state_100mhz", "state_200mhz", "sleep"; + pinctrl-0 = <&pinctrl_usdhc0>; + pinctrl-1 = <&pinctrl_usdhc0>; + pinctrl-2 = <&pinctrl_usdhc0>; + pinctrl-3 = <&pinctrl_usdhc0>; + cd-gpios = <&gpio2 28 GPIO_ACTIVE_LOW>; + status = "okay"; +};diff --git a/arch/arm/boot/dts/imxrt1050.dtsi b/arch/arm/boot/dts/imxrt1050.dtsi new file mode 100644 index 000000000000..35943a6896fa --- /dev/null +++ b/arch/arm/boot/dts/imxrt1050.dtsi@@ -0,0 +1,165 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (C) 2019 + * Author(s): Giulio Benetti <giulio.benetti@benettiengineering.com> + */ + +#include "armv7-m.dtsi" +#include <dt-bindings/interrupt-controller/arm-gic.h> +#include <dt-bindings/clock/imxrt1050-clock.h> +#include <dt-bindings/gpio/gpio.h> + +/ { + #address-cells = <1>; + #size-cells = <1>; + + clocks { + osc: osc { + compatible = "fsl,imx-osc", "fixed-clock";
