If this way occures wrong, then it's only my fault, since I've taken it
myself, without consulting it neither on omap nor media list, so I'm not
going to blame anyone except myself.

It looked like the most simple way for me. And while implementing it, I
haven't faced any restrictions that would lead me to changing my mind and
doing it another way.

I think so, but let's see what OMAP guys have to say.

Since not all patches from the series are OMAP related, and those that are
not, don't depend on others, I think you could have a look at 4/6 and see if
it makes sense or not. You could also examine 6/6 and see if you would like
the idea of a camera LED trigger implemented, this way or another, at the
soc_camera framework level rather than specific machine or platform. Last,
the sensor driver (3/6), even if soc_camera specific, could be considered, if
accepted, for adopting it as a regular v4l2-subdev, if required by a
different implementation of OMAP part choosen.
