2013-01-06[media] s5p-mfc: Move firmware allocation point to avoid allocation problemsKamil Debski1-12/+17
Move firmware allocation from open to probe to avoid problems when using CMA for allocation. In certain circumstances CMA may allocate buffer that is not in the beginning of the MFC memory area.

2012-11-26[media] s5p-mfc: Handle multi-frame input bufferArun Kumar K1-5/+2
When one input buffer has multiple frames, it should be fed again to the hardware with the remaining bytes. Removed the check for P frame in this scenario as this condition can come with all frame types.
