* [media] V4L2: soc-camera: work around unbalanced calls to .s_power()Guennadi Liakhovetski2013-10-311-0/+14
| | | | | | | | | | | | | | | | | | | | Some non soc-camera drivers, e.g. em28xx, use subdevice drivers, originally written for soc-camera, which use soc_camera_power_on() and soc_camera_power_off() helpers to implement their .s_power() methods. Those helpers in turn can enable and disable a clock, if it is supplied to them as a parameter. This works well when camera host drivers balance their calls to subdevices' .s_power() methods. However, some such drivers fail to do that, which leads to unbalanced calls to v4l2_clk_enable() / v4l2_clk_disable(), which then in turn produce kernel warnings. Such behaviour is wrong and should be fixed, however, sometimes it is difficult, because some of those drivers are rather old and use lots of subdevices, which all should be tested after such a fix. To support such drivers this patch adds a work-around, allowing host drivers or platforms to set a flag, in which case soc-camera helpers will only enable the clock, if it is disabled, and disable it only once on the first call to .s_power(0).

* [media] soc-camera: add host clock callbacks to start and stop the master clockGuennadi Liakhovetski2013-06-211-0/+2
| | | | | | | | | | | | | | Currently soc-camera uses a single camera host callback to activate the interface master clock and to configure the interface for a specific client. However, during probing we might not have the information about a client, we just need to activate the clock.

This is now fixed.

* [media] soc-camera: properly fix camera probing racesGuennadi Liakhovetski2013-01-051-1/+1
| | | | | | | | | | | | | | | | The recently introduced host_lock causes lockdep warnings, besides, list enumeration in scan_add_host() must be protected by holdint the list_lock. OTOH, holding .video_lock in soc_camera_open() isn't enough to protect the host during its building of the pipeline, because .video_lock is per soc-camera device. If, e.g. more than one sensor can be attached to a host and the user tries to open both device nodes simultaneously, host's .add() method can be called simultaneously for both sensors. Fix these problems by holding list_lock instead of .host_lock in scan_add_host() and taking it shortly at the beginning of soc_camera_open(), and using .host_lock to protect host's .add() and .remove() operations only.

| | | | | | | | | | | | | | | | | | | | | | | | | | of the framework The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver.

| | | | | | | | | Add an soc-camera host livecrop operation to implement live zoom. If a host driver implements it, it should take care to preserve output frame format, then live crop doesn't break streaming.

| | | | | | | | | | | enum_mbus_fmt received an index argument that was defined as an int instead of an unsigned int. This is now fixed. This had the knock-on effect that the index argument in the callback get_formats in soc_camera.h also had to be changed to unsigned int.
