* [media] mt9t112: mt9t111 format set up differs from mt9t112Guennadi Liakhovetski2013-02-131-5/+13
| | | | | | | | | | | | | The original commit, adding the mt9t112 driver said, that mt9t111 and mt9t112 had identical register layouts. This however doesn't seem to be the case. At least pixel format selection in the mt9t111 datasheet is different from the driver implementation. So far only the default YUYV format has been verified to work with mt9t111. Limit the driver to only report one supported format with mt9t111 until more formats are implemented.

| * [media] mt9v022: fix the V4L2_CID_EXPOSURE controlAnatolij Gustschin2012-11-221-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] mt9v022: support required register settings in snapshot modeAnatolij Gustschin2012-11-221-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some camera systems cannot operate mt9v022 in normal mode and use only the snapshot mode. The TechNote for mt9v022 (TN0960) and mt9v024 (TN-09-225) describes required register settings when configuring the snapshot operation. The snapshot mode requires that certain automatic functions of the image sensor should be disabled or set to fixed values. According to the TechNote bit 2 and bit 9 in the register 0x20 must be set in snapshot mode and unset for normal operation. This applies for mt9v022 Rev.3 and mt9v024. Add required reg. 0x20 settings dependent on sensor chip version.

* [media] soc-camera: Push probe-time power management to driversLaurent Pinchart2012-08-1514-103/+204
| | | | | | | | | | | | | | | | | 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.
