This patchset converts the imx-media driver and its dependent
subdevs to use subdev notifiers.
There are a couple shortcomings in v4l2-core that prevented
subdev notifiers from working correctly in imx-media:

Hi Jacopo,
I tested this patch on the i.MX6Q SabreSD with the OV5640 module.
It fixes the LP-11 timeout at stream on, but the captured images

Hi,
yes! From a first look this nails it for me. Thanks for doing it.

This adds Serial Camera Control Bus (SCCB) helpers (sccb_is_available,
sccb_read_byte, and sccb_write_byte) that are intended to be used by some
of Omnivision sensor drivers.
The ov772x driver is going to use these helpers.
