Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"This series contains:
- Exynos s5p-mfc driver got support for VP8 encoder
- Some SoC drivers gained support for asynchronous registration
(needed for DT)
- The RC subsystem gained support for RC activity LED;
- New drivers added: a video decoder(adv7842), a video encoder
(adv7511), a new GSPCA driver (stk1135) and support for Renesas
R-Car (vsp1)
- the first SDR kernel driver: mirics msi3101. Due to some troubles
with the driver, and because the API is still under discussion, it
will be merged at staging for 3.12. Need to rework on it
- usual new boards additions, fixes, cleanups and driver
improvements"
