[media] mt9v022: fix the V4L2_CID_EXPOSURE control

2012-11-22T12:59:49+00:00

Since the MT9V022_TOTAL_SHUTTER_WIDTH register is controlled in manual
mode by V4L2_CID_EXPOSURE control, it shouldn't be written directly in
mt9v022_s_crop(). In manual mode this register should be set to the
V4L2_CID_EXPOSURE control value. Changing this register directly and
outside of the actual control function means that the register value
is not in sync with the corresponding control value. Thus, the following
problem is observed:
    - setting this control initially succeeds
    - VIDIOC_S_CROP ioctl() overwrites the MT9V022_TOTAL_SHUTTER_WIDTH
      register
    - setting this control to the same value again doesn't
      result in setting the register since the control value
      was previously cached and doesn't differ
Remove MT9V022_TOTAL_SHUTTER_WIDTH register setting in mt9v022_s_crop()
and add a comment explaining why it is not needed in manual mode.

[media] ov2640: select sensor register bank before applying h/v-flip settings

2012-10-06T12:21:27+00:00

We currently don't select the register bank in ov2640_s_ctrl, so we can end up
writing to DSP register 0x04 instead of sensor register 0x04.
This happens for example when calling ov2640_s_ctrl after ov2640_s_fmt.

[media] v4l2: make vidioc_s_crop const

2012-09-26T14:02:25+00:00

Write-only ioctls should have a const argument in the ioctl op.
Do this conversion for vidioc_s_crop.
Adding const for write-only ioctls was decided during the 2012 Media Workshop.

[media] ov772x: Make to_ov772x convert from v4l2_subdev to ov772x_priv

2012-08-15T20:10:49+00:00

Conversion from i2c_client to ov772x_priv is only needed in a single
location, while conversion from v4l2_subdev to ov772x_priv is needed in
several locations. Perform the former manually, and use to_ov772x for
the later.
