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
