[PATCH v5 0/3] arm64: dts: Add support for Ultratronik i.MX8MP Ultra-MACH SBC

[Goran Rađenović]

This patch series adds support for the Ultratronik i.MX8MP-based Ultra-MACH SBC.

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  - Removed an outdated comment.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!

Link to v2 DTS review:
[2] https://lore.kernel.org/all/aEmh7VL7BHkXp5Fu@lizhi-Precision-Tower-5810/

The board is based on NXP's i.MX8MP SoC and includes eMMC, LPDDR4, USB-C, Ethernet, and HDMI.

Tested with:
- `make ARCH=arm64 dtbs_check` (passes)
- Boot tested on hardware

Best regards,

[PATCH v5 1/3] MAINTAINERS: Add i.MX8MP Ultra-MACH SBC to ULTRATRONIK BOARD SUPPORT

[Goran Rađenović]

The i.MX8MP-based Ultra-MACH SBC is supported by Ultratronik, and its
device tree has been added under arch/arm64/boot/dts/freescale/.

To ensure proper maintainer coverage and notification of relevant
changes, add the imx8mp-ultra-mach-sbc.dts file to the existing
ULTRATRONIK BOARD SUPPORT section.

This follows the established pattern already used for the STM32MP157C-
based Ultra-FLY SBC.
