2014-09-02[media] vivid: add the kthread code that controls the video rateHans Verkuil
Add the kthread handlers for video/vbi capture and video/vbi output. These carefully control the rate at which frames are generated (video capture) and accepted (video output). While the short-term jitter is around the order of a jiffie, in the long term the rate matches the configured framerate exactly. The capture thread handler also takes care of the video looping and of capture and overlay support. This is probably the most complex part of this driver due to the many combinations of crop, compose and scaling on the input and output, and the blending that has to be done if overlay support is enabled as well.

2014-09-02[media] vb2: fix multiplanar read() with non-zero data_offsetHans Verkuil
If this is a multiplanar buf_type and the plane we want to read has a non-zero data_offset, then that data_offset was not taken into account. Note that read() or write() for formats with more than one plane is currently not allowed, hence the use of 'planes[0]' since this is only relevant for a single-plane format.

Maximum satellite symbol rate used is 45000000Sps which overflows when multiplied by 135. As final calculation result is fraction, we could use mult_frac macro in order to keep calculation inside 32 bit number limits and prevent overflow. Original bug and fix was provided by Nibble Max. I decided to implement it differently as it is now.

2014-09-02[media] sp2: Add I2C driver for CIMaX SP2 common interface moduleOlli Salonen
Driver for the CIMaX SP2 common interface chip. It is very much based on the existing cimax2 driver for cx23885, but should be more reusable. The product has been sold with name Atmel T90FJR as well and the data sheets for that chip seem to be publicly available. It seems that the USB device that I have and the cx23885 based devices will need to interact differently with the chip for the CAM operations. Thus there is one callback function that is passed on to the sp2 driver (see function sp2_ci_op_cam for that one). IRQ functionality is not included currently (not needed by USB devices and I don't have a PCIe device for development).
