Subject: [PATCH v2 3/3] arm64: dts: ti: var-som-am62p: Add support for Variscite Symphony Board
Add device tree support for the Variscite Symphony carrier board with
the VAR-SOM-AM62P system on module.
The Symphony board includes
- uSD Card support
- USB ports and OTG
- Additional Gigabit Ethernet interface
- Uart interfaces
- OV5640 Camera support
- GPIO Expander
- CAN, I2C and general purpose interfaces
