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.
