The Ultra-MACH SBC is an industrial-grade single-board computer based on the NXP i.MX8M Plus SoC. This initial support includes: - Updating the MAINTAINERS file to include the new board in the Ultratronik support section. - Adding a compatible string entry for the board to `fsl.yaml` in device tree bindings. - Introducing a new device tree source file `imx8mp-ultra-mach-sbc.dts` with basic hardware support. This series is modeled after the support added for the STM32MP157C-based Ultra-FLY SBC and aims to follow the conventions used for other i.MX8MP boards in mainline.. Changes in v2: - Use `enum` with `const:` values in fsl.yaml to correctly represent multiple compatibles. - Updated SPI child node name to use the generic `nfc-transceiver` per DT naming conventions. - Renamed several peripheral nodes (`crypto@35`, `pmic@25`, etc.) to standard names. - Minor formatting cleanup and compliance fixes per review feedback. Changes in v3: - Added "ultratronik,imx8mp-ultra-mach-sbc" to the shared i.MX8MP enum block in `fsl.yaml` [1]. - Ensured the compatible entry is validated by the existing binding structure. - Updated `imx8mp-ultra-mach-sbc.dts` to address review feedback from v2 [2], including: - Proper formatting and indentation fixes. - Cleaned up node ordering and property alignment. Changes in v4: - Moved `status = "okay";` to the last property in the TPM node. - Fixed indentation of `cs-gpios` multi-line property in the ecspi2 node. - Removed an outdated comment. Changes in v5: - Reordered and grouped pinctrl-names and pinctrl-0 at the top of nodes for consistency. - Removed redundant status = "okay"; from TPM and NFC nodes, as their parent nodes already enable them. - Inserted required newlines between properties and child nodes (e.g., in ports {} block). - Cleaned up minor formatting and property order issues in regulator and gpio-leds nodes. No functional changes otherwise. Patch series is based on feedback from Frank Li, Krzysztof Kozlowski and Shawn Guo. Thanks for the reviews!
