The best  should be, I think, to have some guidelines and than the
possibility to choose the best policy for each situation.
In my board I needed to shutdown video in capture and demodulator
circuit, so I have implemented vpfe capture switch off, that does
stream_off to all its v4l2 subdevices (a pal decoder and a video
demodulator).
So I can save 30mA, and it allows to my board to survive longer.
I need to do some tests and have some data with and without PM loss.

Bye,
raffaele
