Merge tag 'media/v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: "Media updates for v4.12-rc1: - new driver to support mediatek jpeg in hardware codec - rc-lirc, s5p-cec and st-cec staging drivers got promoted - hardware histogram support for vsp1 driver - added Virtual Media Controller driver, to make easier to test the media controller - added a new CEC driver (rainshadow-cec) - removed two staging LIRC drivers for obscure hardware that are too obsolete - added support for Intel SR300 Depth camera - some improvements at CEC and RC core - lots of driver cleanups, improvements all over the tree With this series, we're finally getting rid of the LIRC staging driver. There's just one left (lirc_zilog), with require more care, as part of its functionality (IR RX) is already provided by another driver. Work in progress to convert it on the proper way" * tag 'media/v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (304 commits) [media] ov2640: print error if devm_*_optional*() fails [media] atmel-isc: Fix the static checker warning [media] ov2640: add support for MEDIA_BUS_FMT_YVYU8_2X8 and MEDIA_BUS_FMT_VYUY8_2X8 [media] ov2640: fix vflip control [media] ov2640: fix duplicate width+height returning from ov2640_select_win() [media] ov2640: add missing write to size change preamble [media] ov2640: add information about DSP register 0xc7 [media] ov2640: improve banding filter register definitions/documentation [media] ov2640: fix init sequence alignment [media] ov2640: make GPIOLIB an optional dependency [media] xc5000: fix spelling mistake: "calibration" [media] vidioc-queryctrl.rst: fix menu/int menu references [media] media-entity: only call dev_dbg_obj if mdev is not NULL [media] pixfmt-meta-vsp1-hgo.rst: remove spurious '-' [media] mtk-vcodec: avoid warnings because of empty macros [media] coda: bump maximum number of internal framebuffers to 17 [media] media: mtk-vcodec: remove informative log [media] subdev-formats.rst: remove spurious '-' [media] dw2102: limit messages to buffer size [media] ttusb2: limit messages to buffer size ...
