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 * tag 'media/v3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (321 commits) [media] dvb_net: Convert local hex dump to print_hex_dump_debug [media] dvb_net: Use standard debugging facilities [media] dvb_net: Use vsprintf %pM extension to print Ethernet addresses [media] staging: lirc_serial: adjust boolean assignments [media] stb0899: use sign_extend32() for sign extension [media] si2168: add support for 1.7MHz bandwidth [media] si2168: return error if set_frontend is called with invalid parameters [media] lirc_dev: avoid potential null-dereference [media] mn88472: simplify bandwidth registers setting code [media] dvb: tc90522: re-add symbol-rate report [media] lmedm04: add read snr, signal strength and ber call backs [media] lmedm04: Create frontend call back for read status [media] lmedm04: create frontend callbacks for signal/snr/ber/ucblocks [media] lmedm04: Fix usb_submit_urb BOGUS urb xfer, pipe 1 != type 3 in interrupt urb [media] lmedm04: Increase Interupt due time to 200 msec [media] cx88-dvb: whitespace cleanup [media] rtl28xxu: properly initialize pdata [media] rtl2832: declare functions as static [media] rtl2830: declare functions as static [media] rtl2832_sdr: add kernel-doc comments for platform_data ...

- Todo:
-
- *Add a working EPP mode, since DMA ECP read isn't implemented
- in the parport drivers. (That's why it's so sloow)
-
- *Add support for other ccd-control chips than the saa7111
- please send me feedback on what kind of chips you have.
-
- *Add proper probing. I don't know what's wrong with the IEEE1284
- parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
- and nibble read seems to be broken for some peripherals.
-
- *Add probing for onboard SRAM, port directions etc. (if possible)
-
- *Add support for the hardware compressed modes (maybe using v4l2)
-
- *Fix better support for the capture window (no skewed images, v4l
- interface to capt. window)
-
- *Probably some bugs that I don't know of
-
- Please support me by sending feedback!
-
- Changes:
-
- Alan Cox: Removed RGB mode for kernel merge, added THIS_MODULE
- and owner support for newer module locks

- This is a video4linux driver for Telegent tlg2300 based TV cards.
- The driver supports V4L2, DVB-T and radio.
-
- This driver is deprecated and will be removed soon. If you have
- hardware for this and you want to work on this driver, then contact
- the linux-media mailinglist.
-
- To compile this driver as a module, choose M here: the
- module will be called poseidon
