* [media] v4l2: remove g/s_crop from video opsHans Verkuil2016-08-241-23/+18
| | | | | | | | | | | | | | Replace all calls to g/s_crop by calls to the get/set_selection pad ops. Remove the old g/s_crop video ops since they are now no longer used. The cropcap video op is now only used to pass pixelaspect information, and is only needed if the pixelaspect is not 1:1.

* [media] v4l2: replace try_mbus_fmt by set_fmtHans Verkuil2015-05-011-25/+11
| | | | | | | | | | | | | | | The try_mbus_fmt video op is a duplicate of the pad op. Replace all uses in sub-devices by the set_fmt() pad op. Since try_mbus_fmt and s_mbus_fmt both map to the set_fmt pad op (but with a different 'which' argument), this patch will replace both try_mbus_fmt and s_mbus_fmt by set_fmt.

* [media] media: ov2640: add async probe functionJosh Wu2015-04-021-14/+22
| | | | | | | | | | | | In async probe, there is a case that ov2640 is probed before the host device which provided 'mclk'. To support this async probe, we will get 'mclk' at first in the probe(), if failed it will return -EPROBE_DEFER. That will let ov2640 wait for the host device probed.

* [media] soc-camera: Push probe-time power management to driversLaurent Pinchart2012-08-151-3/+8
| | | | | | | | | | | | | | | | | 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 perform the same operations. Fix the problem by pushing the power up/down from the soc-camera core down to individual drivers on a needs basis.

| | | | | | | | | | | | | Instead of forcing all soc-camera drivers to go through the mid-layer to handle power management, create soc_camera_power_[on|off]() functions that can be called from the subdev .s_power() operation to manage regulators and platform-specific power handling. This allows non soc-camera hosts to use soc-camera-aware clients.
