This is the first very crude shot at the subdevice pad-level API wrapper.
The actual wrapper is added in patch #21, previous 20 patches are
preparation... They apply on top of the last version of my async / clock
patch series, respectively, on top of the announced branch of my linuxtv
git-tree. Patches 2 and 4 from this series should actually be merged into
respective patches from the async series.
I'm publishing this patch-series now, because I don't know when and how
much time I'll have to improve it... Maybe you don't want to spend too much
time reviewing implementation details, but comments to general concepts
would be appreciated.
Further note, that patches 8-12 aren't really required. We can keep the
deprecated struct soc_camera_link for now, or use a more gentle and slow
way to remove it.
