Merge tag 'media/v3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Some documentation updates and a few new pixel formats

 - Stop btcx-risc abuse by cx88 and move it to bt8xx driver

 - New platform driver: am437x

 - New webcam driver: toptek

 - New remote controller hardware protocols added to img-ir driver

 - Removal of a few very old drivers that relies on old kABIs and are
   for very hard to find hardware: parallel port webcam drivers
   (bw-qcam, c-cam, pms and w9966), tlg2300, Video In/Out for SGI (vino)

 - Removal of the USB Telegent driver (tlg2300).  The company that
   developed this driver has long gone and the hardware is hard to find.
   As it relies on a legacy set of kABI symbols and nobody seems to care
   about it, remove it.

 - several improvements at rtl2832 driver

 - conversion on cx28521 and au0828 to use videobuf2 (VB2)

 - several improvements, fixups and board additions
