[PATCH v3 0/6] arm64: dts: imx8mp-var-som: align DTS with hardware revision

[Stefano Radaelli <stefano.radaelli21@gmail.com>]

This patch series aligns the VAR-SOM-MX8MP device tree with the actual
hardware populated on the System-on-Module, and separates SOM-specific
descriptions from carrier-board-specific ones.

The first three patches move the USDHC2 interface, the PCA9534 GPIO
expander, and the UART2 debug console out of the SOM dtsi, as these
components are not present on the VAR-SOM-MX8MP module itself and are
instead routed on the Symphony carrier board. Their descriptions are
therefore provided in the carrier board DTS, keeping the SOM device
tree limited to on-module hardware.

The remaining patches add support for peripherals that are populated
on the SOM and commonly used across designs, including WiFi/Bluetooth
connectivity, the WM8904 audio codec, and the ADS7846 touchscreen
controller.

Overall, this series ensures a clear separation between SOM and carrier
board responsibilities in the device tree, avoids describing
non-existent hardware on the module, and enables key on-module
features.
v3:
 - Remove unnecessary status property
v2:
 - Move deleted nodes from SOM dts to Symphony carrier board
