Looking at the separation you've done here, I don't see why you need
it. All the resources you request are generic, so why not just adding a
new compat in the of_match_table?

Just realized the driver is named dw-i3c-master, while the cadence
driver is named i3c-master-cdns.c. I'll send a patch to make that
consistent and follow the initial naming scheme: i3c-master-<ipname>.c.
