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 include: - a new Remote Controller driver for ST SoC with the corresponding DT bindings - a new frontend (cx24117) - a new I2C camera flash driver (lm3560) - a new mem2mem driver for TI SoC (ti-vpe) - support for Raphael r828d added to r820t driver - some improvements on buffer allocation at VB2 core - usual driver fixes and improvements PS this time, we have a smaller number of patches. While it is hard to pinpoint to the reasons, I believe that it is mainly due to: 1) there are several patch series ready, but depending on DT review. I decided to grant some extra time for DT maintainers to look on it, as they're expecting to have more time with the changes agreed during ARM mini-summit and KS. If they can't review in time for 3.14, I'll review myself and apply for the next merge window. 2) I suspect that having both LinuxCon EU and LinuxCon NA happening during the same merge window affected the development productivity, as several core media developers participated on both events" * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (151 commits) [media] media: st-rc: Add ST remote control driver [media] gpio-ir-recv: Include linux/of.h header [media] tvp7002: Include linux/of.h header [media] tvp514x: Include linux/of.h header [media] ths8200: Include linux/of.h header [media] adv7343: Include linux/of.h header [media] v4l: Fix typo in v4l2_subdev_get_try_crop() [media] media: i2c: add driver for dual LED Flash, lm3560 [media] rtl28xxu: add 15f4:0131 Astrometa DVB-T2 [media] rtl28xxu: add RTL2832P + R828D support [media] rtl2832: add new tuner R828D [media] r820t: add support for R828D [media] media/i2c: ths8200: fix build failure with gcc 4.5.4 [media] Add support for KWorld UB435-Q V2 [media] staging/media: fix msi3101 build errors [media] ddbridge: Remove casting the return value which is a void pointer [media] ngene: Remove casting the return value which is a void pointer [media] dm1105: remove unneeded not-null test [media] sh_mobile_ceu_camera: remove deprecated IRQF_DISABLED [media] media: rcar_vin: Add preliminary r8a7790 support ...
