A bug in the ov7670 sensor causes it to introduce noise unless the CLKRC register is rewritten *after* setting the image mode. Naturally, resetting CLKRC in this way will cause other modes to fail. So carefully poke the register only when indicated. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
The proper method for powering down the sensor on OLPC systems has changed somewhat; in particular, the sensor must be powered down completely (rather than simply told to power down) or the associated "camera active" LED will stay on.

Allow to use SECAM-BG with the FI1216MF tuner. The selection is done with the secam=B module argument. The default behaviour should be the same as before.

dvb-core is not started early enough when device drivers that use dvb are compiled in so dvb_register_device fails (silently) since dvb_class is NULL, this runs dvb_init using subsys_initcall instead of module_init. dvb_register_device will now check the return value of class_device_create.

Reverted the change to struct v4l2_pix_format. I completely missed that this struct was used by existing ioctls so that changing it broke the ABI. I will have to think of another way of setting the top/left coordinates but for now this change is reverted to preserve compatibility.
