It is preferable to have the patch description make sense standalone
even when read without the subject line.

Please follow the subject line conventions of the subsystem the patch is
touching. This is not an ARM patch so the "ARM: davinci: " prefix in
subject is surely wrong.

And I think I mentioned this once before but we want to see
Kconfig/Makefile changes along with driver addition in the same patch.

Its nice to keep the selects sorted. It helps avoid duplicates.

No need of this I think, it should default to no already.

I hope running modinfo gives these details as well.

I think this is misleading a bit since just selecting 'n' here will not
result in a "bare minimum kernel" - better to just avoid mention of it.
