From: Stefano Radaelli <stefano.r@variscite.com>
Add device tree support for the Variscite DART-MX93 system on module.
This SOM is designed to be used with various carrier boards.
The module includes:
- NXP i.MX93 MPU processor
- Up to 2GB 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.

From: Stefano Radaelli <stefano.r@variscite.com>
Add device tree support for the Variscite Sonata carrier board with the
DART-MX93 system on module.
The Sonata board includes
- uSD Card support
- USB ports and OTG
- Additional Gigabit Ethernet interface
- Uart, SPI and I2C interfaces
- GPIO Expanders
- RTC module
- TPM module
- CAN peripherals
