Hello.

Could you please let me know how to check whether my RK3568 is v2 or v3?

Alexander Shiyan (Cc'ed) reads the information from an nvmem cell:

The idea is to fixup the device tree in the bootloader depending on the
SoC revision, so that the CAN driver uses only the needed workarounds.

Thanks, it is not easy to correlate this because I am currently not using
barebox. I'll try this later.

I think this can be done from the userspace.
Build the driver as a module, get the SoC version, then modprobe it
with an alias for the desired version.
