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: - removal of sn9c102. This device driver was replaced a long time ago by gspca - solo6x10 and go7007 webcam drivers moved from staging into mainstream. They were waiting for an API to allow setting the image detection matrix - SDR drivers moved from staging into mainstream: sdr-msi3101 (renamed as msi2500) and rtl2832 - added SDR driver for airspy - added demux driver: si2165 - rework at several RC subsystem, making the code for RC-5 SZ variant to be added at the standard RC5 decoder - added decoder for the XMP IR protocol - tuner driver moved from staging into mainstream: msi3101 (renamed as msi001) - added documentation for some additional SDR pixfmt - some device tree bindings documented - added support for exynos3250 at s5p-jpeg - remove the obsolete, unmaintained and broken mx1_camera driver - added support for remote controllers at au0828 driver - added a RC driver: sunxi-cir - several driver fixes, enhancements and cleanups. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (455 commits) [media] cx23885: fix UNSET/TUNER_ABSENT confusion [media] coda: fix build error by making reset control optional [media] radio-miropcm20: fix sparse NULL pointer warning [media] MAINTAINERS: Update go7007 pattern [media] MAINTAINERS: Update solo6x10 patterns [media] media: atmel-isi: add primary DT support [media] media: atmel-isi: convert the pdata from pointer to structure [media] media: atmel-isi: add v4l2 async probe support [media] rcar_vin: add devicetree support [media] media: pxa_camera device-tree support [media] media: mt9m111: add device-tree suppport [media] soc_camera: add support for dt binding soc_camera drivers [media] media: soc_camera: pxa_camera documentation device-tree support [media] media: mt9m111: add device-tree documentation [media] s5p-mfc: remove unnecessary calling to function video_devdata() [media] s5p-jpeg: add chroma subsampling adjustment for Exynos3250 [media] s5p-jpeg: Prevent erroneous downscaling for Exynos3250 SoC [media] s5p-jpeg: Assure proper crop rectangle initialization [media] s5p-jpeg: fix g_selection op [media] s5p-jpeg: Adjust jpeg_bound_align_image to Exynos3250 needs ...
