[PATCH v2 0/7] arm64: dts: freescale: Add Verdin iMX8M Mini overlays

This series adds device tree overlays for the Toradex Verdin iMX8M Mini
SoM. The overlays cover audio configuration, display adapters, DSI
displays, and Cortex-M4F integration.

The series adds support for:
- NAU8822 Bridge Tied Load configuration on the Verdin Development Board
- DSI-to-HDMI adapter based on the Lontium LT8912B bridge
- DSI-to-LVDS adapter based on the TI SN65DSI84 bridge, combined with the
  Toradex Capacitive Touch Display 10.1" LVDS
- Toradex Capacitive Touch Display 7" and 10.1" DSI variants
- Cortex-M4F remoteproc support

Cortex-M4F support is split between the SoM description and an optional
UART_4 overlay. The SoM dtsi describes the remote processor and RPMsg
reserved-memory regions, while the overlay reserves Verdin UART_4 for
Cortex-M4F firmware use.

The Makefile entries build the standalone overlays as DTBOs, add
ready-to-use composed DTBs for selected carrier board and accessory
combinations, and add representative composed DTBs for build-time
coverage.

As discussed in v1, the overlays for the OV5640 cameras will follow
later and use the partial connectors model to specify the Verdin CSI
connector.
