v6 cover Add support for Variscite DART-MX8M-PLUS and Sonata board

This patch series adds support for the Variscite DART-MX8M-PLUS system on module and the Sonata carrier board.

The series includes:
- SOM device tree with on-module peripherals
- Sonata carrier board device tree with board-specific features

The implementation follows the standard SOM + carrier board pattern where the SOM dtsi contains only peripherals mounted on the module, while carrier-specific interfaces are enabled in the board dts.

v5->v6:
-

v4->v5:
- Fix nodes order

v3->v4:
- Add snvs nodes

v2->v3:
- Fixed wrong som eth phy address

v1->v2:
- Fixed wrong sai peripheral reference
- Fixed wrong eqos pinctrl gpio
- Fixed model name
- Added new usdhc2 regulator pinctrl
- Adjusted irq edges

PATCH v6 2/3 arm64: dts: freescale: Add support for Variscite DART-MX8M-PLUS

In reply to Stefano Radaelli

From: Stefano Radaelli <[email protected]>

Add device tree support for the Variscite DART-MX8MP system on module. This SOM is designed to be used with various carrier boards.

The module includes:
- NXP i.MX8M Plus MPU processor
- Up to 8GB of LPDDR4 memory
- Up to 128GB of eMMC storage memory
- Integrated 10/100/1000 Mbps Ethernet Transceiver
- Codec audio WM8904
- WIFI6 dual-band 802.11ax/ac/a/b/g/n with optional 802.15.4 and Bluetooth

Only SOM-specific peripherals are enabled by default. Carrier board specific interfaces are left disabled to be enabled in the respective carrier board device trees.
