Note like all info on the pac73xx chips, this info was found by trial and error, so it is not necessarily 100% correct. Signed-off-by:

We can only control the clockdivider to control exposure on the pac7311, making our expo control coarse, switch to an autogain algorithm optimized for this. Signed-off-by:

Now that the pac7302 and pac7311 drivers are split, they no longer share there control settings, so there is no need to scale the controls to register values, instead make them reflect the registers directly. Signed-off-by:

It turns out that the flush to sensor command needs to be done per register bank. We were missing one such flush in set_exposure, causing exposure changes to only show up when another setting in the same bank also got changed. Signed-off-by:

The pac7302 and pac7311 driver still contains some comments from before they were separated, such as marking certain functions 7302 or 7311 only, with the new split drivers these make no sense, remove them. Also removed the empty/unused sd_stop0 function from pac7311.c Signed-off-by:

Allow users of gspca/autogain_functions.h to declare which of the autogain algoritms they are going to use. This allows us to remove the hacks from drivers which don't use coarse_grained_expo_autogain. Signed-off-by:

Prior to this patch the stk-webcam driver was enabling the vflip and mirror bits in the sensor by default. Which only is the right thing to do if the sensor is actually mounted upside down, which it usually is not. Actually we've received upside down reports for both usb-ids which this driver supports, one for an "ASUSTeK Computer Inc." "A3H" laptop with a build in 174f:a311 webcam, and one for an "To Be Filled By O.E.M." "Z96FM" laptop with a build in 05e1:0501 webcam. Signed-off-by:

Implement the control framework and update to the latest V4L2 framework. The v4l2-compliance tool now runs without errors. Fixed bad g/s_tuner handling with respect to mono/stereo. Support control events. Signed-off-by:

This driver now complies with the v4l2-compliance tests and uses the v4l2 frameworks correctly. It has been tested with the radio-keene FM transmitter as well. Signed-off-by:

At the point of the call to video_register_device, both dev->vbi_dev and dev->vdev have been allocated, and so should be freed on failure. The error-handling code is moved to the end of the function, to avoid code duplication. Signed-off-by:

"stat" is always zero here. The condition used to be needed, but we shifted stuff around in 0f0b270f "[media] ngene: CXD2099AR Common Interface driver". This doesn't change how the code works, it's just a bit tidier. Signed-off-by:

Both radio-keene and dsbr100 did one v4l2_device_get too many. Thus the refcount never became 0 and that causes a memory leak. Also updated the V4L2 framework documentation accordingly. Signed-off-by:
