It should be called when the driver core finds a device that matches
your match table.
When you register your driver the driver core will iterate over all
devices on the platform bus and if they match then it will call your
probe routine.
I assume you've update the compatible property in the match table, I'm
not sure what else could be causing it to not be called.
cheers
