v1 -> v2:
- moved the priority controller node above the cfgchip node
- renamed added nodes to better reflect their purpose

I think we should add status = "disabled"; here and let boards opt in.

Hi David,
I did that initially[1][2] and it was rejected by Kevin[3] and Laurent[4].
FYI this patch has already been queued by Sekhar.
Thanks. I did not see those threads.
FYI to maintainers, having these enabled by default causes error
messages in the kernel log for other boards that are not supported by
the drivers. Since there is only one board that is supported and soon to
be 2 that are not, I would rather have this disabled by default to avoid
the error messages.
Best regards,
Bartosz Golaszewski
