Merge tag 'media/v3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- new IR driver: hix5hd2-ir
- the virtual test driver (vivi) was replaced by vivid, with has an
almost complete set of features to emulate most v4l2 devices and
properly test all sorts of userspace apps
- the as102 driver had several bugs fixed and was properly split into a
frontend and a core driver. With that, it got promoted from staging
into mainstream
- one new CI driver got added for CIMaX SP2/SP2HF (sp2 driver)
- one new frontend driver for Toshiba ISDB-T/ISDB-S demod (tc90522)
- one new PCI driver for ISDB-T/ISDB-S (pt3 driver)
- saa7134 driver got support for go7007-based devices
- added a new PCI driver for Techwell 68xx chipsets (tw68)
- a new platform driver was added (coda)
- new tuner drivers: mxl301rf and qm1d1c0042
- a new DVB USB driver was added for DVBSky S860 & similar devices
- added a new SDR driver (hackrf)
- usbtv got audio support
- several platform drivers are now compiled with COMPILE_TEST
- a series of compiler fixup patches, making sparse/spatch happier with
the media stuff and removing several warnings, especially on those
platform drivers that didn't use to compile on x86
- Support for several new modern devices got added
- lots of other fixes, improvements and cleanups
