* [media] s5p-fimc: Refactor hardware setup for m2m transactionSylwester Nawrocki2012-04-10

* [media] s5p-fimc: Reinitialize the pipeline properly after VIDIOC_STREAMOFFSylwester Nawrocki2012-04-10
| | | | | | | | | | | | This patch prevents blocking on DQBUF at a video capture node in some conditions, after STREAOMOFF/STREAMON sequence. The ST_CAPT_SUSPEND flag should not be set during normal stream off, otherwise the capture engine is not properly enabled at stream on.

* [media] s5p-fimc: Don't use platform data for CSI data alignment configurationSylwester Nawrocki2012-04-10
| | | | | | | | | | | | The MIPI-CSI2 data alignment parameter can be derived from media bus pixel code, so it can be now dropped from the platform data structure. This is a prerequisite for adding the device tree support. Once this patch is merged the corresponding fields will be removed from the drivers' public headers and corresponding board files.
