From: Stefano Radaelli <stefano.r@variscite.com>
Add device tree support for the Variscite VAR-SOM-MX8 QuadMax
system on module.
This SOM is designed to be used with various carrier boards.
The module includes:
- NXP i.MX8 QuadMax 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.

Add device tree support for the Variscite Symphony carrier board with
the VAR-SOM-MX8 QuadMax system on module.
The Symphony 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
- PCIE support
