Hey,
This is a v2 adding support for the Variscite VAR-SOM-MX93 SoM on Symphony
Board.
Support for "nxp,pca9451a" is not mainlined yet, it has been proposed here:
https://lore.kernel.org/lkml/[email protected]/T/
I removed it from the device-tree for now.
Thanks,
Signed-off-by: Mathieu Othacehe <[email protected]>

Changes in v2:
- Remove "nxp,pca9451a" block
- Fixed checkpatch warnings
- Fixed dtb_checks warnings
- Introduce dt-bindings documentation
v1: https://lore.kernel.org/linux-devicetree/[email protected]/T/#t
