Merge branch 'topic/exynos' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull exynos media updates from Mauro Carvalho Chehab: "These are the remaining patches I have for the merge windows. It basically adds a new sensor and adds the needed DT bits for it to work" * 'topic/exynos' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] s5p-fimc: Remove reference to outdated macro [media] s5p-jpeg: Fix broken indentation in jpeg-regs.h [media] exynos4-is: Add the FIMC-IS ISP capture DMA driver [media] exynos4-is: Add support for asynchronous subdevices registration [media] exynos4-is: Add clock provider for the SCLK_CAM clock outputs [media] exynos4-is: Use external s5k6a3 sensor driver [media] V4L: s5c73m3: Add device tree support [media] V4L: Add driver for s5k6a3 image sensor [media] Documentation: devicetree: Update Samsung FIMC DT binding [media] Documentation: dt: Add binding documentation for S5C73M3 camera [media] Documentation: dt: Add binding documentation for S5K6A3 image sensor
