I trust Arnd's research that the driver becomes unused after the PXA
removal. I can add to it that the plain TMIO driver hasn't seen any
functional update in 10 years maybe. Most modifications were tree-wide
cleanups or adjustments because the TMIO core changed. It will be
interesting to see what cleanups can be done once this driver is gone.
