Given that all other approaches that have been tried have failed, this seems like the best way forward. I don't know enough about the driver to do a detailed review, but all patches looked good to me as far as I could tell. One question: How does the name space and minor number allocation work if you have both sbsa-uart and real pl011 in the same system? Do they share the ttyAMA name space without collisions?
