I only noticed the series after Joel asked about the DT changes on the arm
side. One question though:
How does this related to the drivers/input/serio/ framework that also talks
to the keyboard controller for things that are not keyboards? Are these
separate communication channels on adjacent I/O ports, or does there
need to be some arbitration?
