[PATCH v2 9/9] soc-camera: Push probe-time power management to drivers

2012-07-05 Thread Laurent Pinchart
Several client drivers access the hardware at probe time, for instance to read the probe chip ID. Such chips need to be powered up when being probed. soc-camera handles this by powering chips up in the soc-camera probe implementation. However, this will break with non soc-camera hosts that don't p
