-/* BT848 Driver for Brooktree's Bt848, Bt848A, Bt849A, Bt878, Bt879 based cards.
- The Brooktree BT848 Driver driver is based upon Mark Tinguely and
- Jim Lowe's driver for the Matrox Meteor PCI card . The
- Philips SAA 7116 and SAA 7196 are very different chipsets than
- the BT848. For starters, the BT848 is a one chipset solution and
- it incorporates a RISC engine to control the DMA transfers --
- that is it the actual dma process is control by a program which
- resides in the hosts memory also the register definitions between
- the Philips chipsets and the Bt848 are very different.
-
- The original copyright notice by Mark and Jim is included mostly
- to honor their fantastic work in the Matrox Meteor driver!
-
- Enjoy,
- Amancio
-
- The Bt848 was discontinued in July 1999.

- renamed as Conexant.)

- converts the brightness value from unsigned to
- signed.
-1.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,

- options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
- in the kernel config file makes the driver's
- video_open() function select PAL rather than NTSC.
- This fixed all the hangs on my Dual Crystal card
- when using a PAL video signal. As a result, you
- can loose the tsleep (of 2 seconds - now 0.25!!)
- which I previously added. (Unless someone else
- wanted the 0.25 second tsleep).
-
-1.36 added bt848.format sysctl variable.
- 1 denotes NTSC , 0 denotes PAL
-
-1.37 added support for Bt878 and improved Hauppauge's
- bt848 tuner recognition
-1.38 Further improvements on Hauppauge's rely on
- eeprom[9] to determine the tuner type 8)
-

- for newer NTSC WinCastTV 404 with Bt878 chipset.
- Tidied up PAL default in video_open()
-
-1.49 10 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
- Added Capture Area ioctl - BT848[SG]CAPAREA.
- Normally the full 640x480 (768x576 PAL) image
- is grabbed. This ioctl allows a smaller area
- from anywhere within the video image to be
- grabbed, eg a 400x300 image from (50,10).
- See restrictions in BT848SCAPAREA.
-
-1.50 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>

- options OVERRIDE_TUNER=11
- options BKTR_USE_PLL
-
-1.51 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
- Fixed bug in Miro Tuner detection. Missing Goto.
- Removed Hauppauge EEPROM 0x10 detection as I think
- 0x10 should be a PAL tuner, not NTSC.
- Reinstated some Tuner Guesswork code from 1.27
-
-1.52 3 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk>

- Added for Yuri Gindin <yuri@xpert.com>
-
-1.62 29 Apr 1999 Added new cards: NEC PK-UG-X017 and I/O DATA GV-BCTV2/PCI
- Added new tuner: ALPS_TSBH1 (plus FM Radio for ALPS_TSCH5)
- Added support for BCTV audio mux.
- All submitted by Hiroki Mori <mori@infocity.co.jp>
-
-1.63 29 Apr 1999 Roger Hardiman <roger@freebsd.org>
- Added initial code for VBI capture based on work by
- Hiroki Mori <mori@infocity.co.jp> and reworked by myself.
- This allows software decoding of teletext, intercast and
- subtitles via /dev/vbi.
-
-1.64 7 May 1999 Roger Hardiman <roger@freebsd.org>
- Support LifeView FlyVideo 98 cards. Use EEPROM for card
- autodetection. Use bttv's audio mux values.
- Thanks to Paul Reece <paul@fastlane.net.au>,
- Ivan Brawley <brawley@internode.com.au> and
- Gilad Rom <rom_glsa@ein-hashofet.co.il>
- Automatically locate the EEPROM i2c address and read the
- subsystem_vendor_id from EEPROM and not the PCI registers.
- Add NSMBUS checks around smbus/iicbus i2c bus code
- making it easier to compile the driver under 2.2.x.
- Add GPIO mask for the audio mux to each card type.
- Add CARD_ZOLTRIX and CARD_KISS from mailing list searches.
-
-1.65 18 May 1999 Roger Hardiman <roger@freebsd.org>
- Change Intel GPIO mask to stop turning the Intel Camera off
- Fixed tuner selection on Hauppauge card with tuner 0x0a
- Replaced none tuner with no tuner for Theo de Raadt.
- Ivan Brawley <brawley@internode.com.au> added
- the Australian channel frequencies.
-
-1.66 19 May 1999 Ivan Brawley <brawley@internode.com.au> added better
- Australian channel frequencies.
-
-1.67 23 May 1999 Roger Hardiman <roger@freebsd.org>
- Added rgb_vbi_prog() to capture VBI data and video at the
- same time. To capture VBI data, /dev/vbi must be opened
- before starting video capture.
-
-1.68 25 May 1999 Roger Hardiman <roger@freebsd.org>
- Due to differences in PCI bus implementations from various
- motherboard chipset manufactuers, the Bt878/Bt879 has 3
- PCI bus compatibility modes. These are
- NORMAL PCI 2.1 for proper PCI 2.1 compatible chipsets.
- INTEL 430 FX for the Intel 430 FX chipset.
- SIS VIA CHIPSET for certain SiS and VIA chipsets.
- Older Intel and non-Intel chipsets may also benefit from
- either 430_FX or SIS/VIA mode.
-
- NORMAL PCI mode is enabled by default.
- For INTEL 430 FX mode, add this to your kenel config:
- options "BKTR_430_FX_MODE"
- For SiS / VIA mode, add this to your kernel config:
- options "BKTR_SIS_VIA_MODE"
-
- Using quotes in these options is not needed in FreeBSD 4.x.
-
- Note. Newer VIA chipsets should be fully PCI 2.1 compatible
- and should work fine in the Default mode.
-
- Also rename 849 to 849A, the correct name for the chip.
-
-1.69 12 June 1999 Roger Hardiman <roger@freebsd.org>
- Updates for FreeBSD 4.x device driver interface.
- BSDI code removed. Will be restored later.
-
-1.70 12 July 1999 Roger Hardiman <roger@freebsd.org>
- Reorganise OS device dependant parts (based on a port to
- linux by Brad Parker).
- Make the driver compile on FreeBSD 2.2.x systems again.
- Change number of VBI lines from 16 to 12 for NTSC formats.
- Changes to probeCard() for better eeprom identification.
- Added STB Bt878 card identification.
- Add Hauppauge model identification to probeCard().
- Added TDA9850 initialisation code taken from Linux bttv.
- Juha.Nurmela@quicknet.inet.fi found/fixed bug in VBI_SLEEP.
- Matt Brown <matt@dqc.org> added MSP3430G DBX initialisation.
-
-1.71 12 July 1999 Roger Hardiman <roger@freebsd.org>
- Small cleanup of OS dependant code. Remove NPCI usage.
- Add VBI sequence numbering for AleVT Teletext package.
- Add support for Hauppauge 627 and Temic 4006 submitted
- by Maurice Castro <maurice@atum.castro.aus.net>

- *
- * The current probe code works as follows
- * 1) Check if it is a BT878. If so, read the sub-system vendor id.
- * Select the required tuner and other onboard features.
- * 2) If it is a BT848, 848A or 849A, continue on:
- * 3) Some cards have no I2C devices. Check if the i2c bus is empty
- * and if so, our detection job is nearly over.
- * 4) Check I2C address 0xa0. If present this will be a Hauppauge card
- * or an Osprey card. The Hauppauge EEPROM can determine on board tuner
- * type and other features.
- * 4) Check I2C address 0xa8. If present this is a STB card.
- * Still have to guess on the tuner type.
- * 5) Otherwise we are in the dark. Miro cards have the tuner type
- * hard-coded on the GPIO pins, but we do not actually know if we have
- * a Miro card.
- * Some older makes of card put Philips tuners and Temic tuners at
- * different I2C addresses, so an i2c bus probe can help, but it is
- * really just a guess.
- *
- * 6) After determining the Tuner Type, we probe the i2c bus for other
- * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
- * stereo chips.
