I don't particularly care as I don't know of anything else that is planned for
this cycle that will touch this driver but generally I'd consider this series
driver changes with additions to the device tree to support new functionality.

The only reason to merge through the arm-soc tree I can see is that there is
likely to be more churn in the device tree files.

There is also the question of whether that missing sample and hold time is
a fix we want to push out this cycle, or whether it can wait for the next
merge window.  I'm not clear from the description.
