The series includes: - DT bindings for the supported VAR-SOM-MX7 board configurations - VAR-SOM-MX7 device tree support, including V1 and V2 hardware revisions - MX7CustomBoard carrier board support - eMMC and NAND storage variants - optional WM8731 audio codec support The implementation follows the standard SOM + carrier board pattern, where the common SOM dtsi contains the on-module peripherals and hardware revision differences, while the MX7CustomBoard dtsi contains the carrier-specific interfaces. The final board device trees combine the supported VAR-SOM-MX7 configurations with the MX7CustomBoard carrier board. v3->v4: - Fixed non-generic names and wrong separators - Fixed ads7846_ts pendown gpio v2->v3: - Removed wrong header in dtsi - Fixed pinctrl name - Fixed sai clocks v1->v2: - Fixed commit messages and spacing - Moved ethphy1 reset pin mux - Fixed irq types - Removed duplicate assigned-clock-rates property - fixed wifi child node name - Added color property in gpio led definition - Updated deprecated reset-gpio property - Added disable-over-current property in usb nodes - Fixed model names Stefano Radaelli (3): dt-bindings: arm: fsl: add Variscite VAR-SOM-MX7 boards ARM: dts: imx7d: add Variscite VAR-SOM-MX7 support ARM: dts: imx7d: add Variscite MX7CustomBoard support .../devicetree/bindings/arm/fsl.yaml | 17 + arch/arm/boot/dts/nxp/imx/Makefile | 6 + .../imx/imx7d-var-som-emmc-mx7customboard.dts | 22 + ...x7d-var-som-emmc-wm8731-mx7customboard.dts | 23 + .../boot/dts/nxp/imx/imx7d-var-som-emmc.dtsi | 99 +++ .../nxp/imx/imx7d-var-som-mx7customboard.dtsi | 382 +++++++++++ .../imx/imx7d-var-som-nand-mx7customboard.dts | 22 + ...x7d-var-som-nand-wm8731-mx7customboard.dts | 23 + .../boot/dts/nxp/imx/imx7d-var-som-nand.dtsi | 73 ++ .../imx7d-var-som-v2-emmc-mx7customboard.dts | 23 + .../imx7d-var-som-v2-nand-mx7customboard.dts | 23 + .../boot/dts/nxp/imx/imx7d-var-som-v2.dtsi | 66 ++ .../dts/nxp/imx/imx7d-var-som-wm8731.dtsi | 65 ++ arch/arm/boot/dts/nxp/imx/imx7d-var-som.dtsi | 635 ++++++++++++++++++ 14 files changed, 1479 insertions(+) create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-emmc-mx7customboard.dts create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-emmc-wm8731-mx7customboard.dts create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-emmc.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-mx7customboard.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-nand-mx7customboard.dts create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-nand-wm8731-mx7customboard.dts create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-nand.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-v2-emmc-mx7customboard.dts create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-v2-nand-mx7customboard.dts create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-v2.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som-wm8731.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx7d-var-som.dtsi base-commit: 9400c5b6aa357be2379c98ae86a207bc21dc7a48 -- 2.47.3
