2014-09-03[media] media: s5p-mfc: rename special clock to sclk_mfcMarek Szyprowski1-1/+1
Commit d19f405a5a8d2ed942b40f8cf7929a5a50d0cc59 ("[media] s5p-mfc: Fix selective sclk_mfc init") added support for special clock handling (named "sclk-mfc"). However this clock is not defined yet on any platform, so before adding it to all Exynos platform, better rename it to "sclk_mfc" to match the scheme used for all other special clocks on Exynos platform.

2014-09-03[media] vivid: add the kthread code that controls the video rateHans Verkuil4-0/+1241
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.

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.
