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 contain: - new i2c video drivers: ml86v7667 (video decoder), ths8200 (video encoder) - a new video driver for EasyCap cards based on Fushicai USBTV007 - Improved support for OF and embedded systems, with V4L2 async initialization and a better support for clocks - API cleanups on the ioctls used by the v4l2 debug tool - Lots of cleanups - As usual, several driver improvements and new cards additions - Revert two changesets that change the minimal symbol rate for stv0399, as request by Manu - Update MAINTAINERS and other files to point to my new e-mail" * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (378 commits) MAINTAINERS & ABI: Update to point to my new email [media] stb0899: restore minimal rate to 5Mbauds [media] exynos4-is: Correct colorspace handling at FIMC-LITE [media] exynos4-is: Set valid initial format on FIMC.n subdevs [media] exynos4-is: Set valid initial format on FIMC-IS-ISP subdev pads [media] exynos4-is: Fix format propagation on FIMC-IS-ISP subdev [media] exynos4-is: Set valid initial format at FIMC-LITE [media] exynos4-is: Fix format propagation on FIMC-LITE.n subdevs [media] MAINTAINERS: Update S5P/Exynos FIMC driver entry [media] Documentation: Update driver's directory in video4linux/fimc.txt [media] exynos4-is: Change fimc-is firmware file names [media] exynos4-is: Add support for Exynos5250 MIPI-CSIS [media] exynos4-is: Add Exynos5250 SoC support to fimc-lite driver [media] exynos4-is: Drop drvdata handling in fimc-lite for non-dt platforms [media] media: i2c: tvp514x: remove manual setting of subdev name [media] media: i2c: tvp7002: remove manual setting of subdev name [media] mem2mem: set missing v4l2_dev pointer [media] wl128x: add missing struct v4l2_device [media] tvp514x: Fix init seqeunce [media] saa7134: Fix sparse warnings by adding __user annotation ...
