/* BT848 Driver for Brooktree's Bt848, Bt849, Bt878 and Bt 879 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

INT_MASK for CAP_CONTINUOUS to be exactly
the same as CAP_SINGLE apparently setting
bit 23 cleared the system lock up.
version 1.1 of the driver has been reported
to work with STB's WinTv, Hauppage's Wincast/Tv
and last but not least with the Intel Smart
Video Recorder.

CAP_SINGLEs that for ODD_ONLY fields.
1.19 9/8/97 improved yuv support , cleaned up weurope
channel table, incorporated cleanup work from
Luigi, fixed pci interface bug due to a
change in the pci interface which disables

on the Bt848 auto video detect feature.
1.21 10/24/97 Randall Hopper <rhh@ct.picker.com>
Fix temporal decimation, disable it when
doing CAP_SINGLEs, and in dual-field capture, don't

<ohashi@atohasi.mickey.ai.kyutech.ac.jp> submitted
code to support bktr_read .
Flemming Jacobsen <fj@schizo.dk.tfs.com>
submitted code to support radio available with in
some bt848 based cards;additionally, wrote code to
correctly recognized his bt848 card.
Roger Hardiman <roger@cs.strath.ac.uk> submitted
various fixes to smooth out the microcode and made
all modes consistent.
1.26 Moved Luigi's I2CWR ioctl from the video_ioctl
section to the tuner_ioctl section
Changed Major device from 79 to 92 and reserved
our Major device number -- hasty@star-gate.com
1.27 Last batch of patches for radio support from
Flemming Jacobsen <fj@trw.nl>.
Added B849 PCI ID submitted by:
Tomi Vainio <tomppa@fidata.fi>
1.28 Frank Nobis <fn@Radio-do.de> added tuner support
for the German Phillips PAL tuner and
additional channels for german cable tv.
1.29 Roger Hardiman <roger@cs.strath.ac.uk>
Revised autodetection code to correctly handle both
old and new VideoLogic Captivator PCI cards.
Added tsleep of 2 seconds to initialistion code
for PAL users.Corrected clock selection code on
format change.
1.30 Bring back Frank Nobis <fn@Radio-do.de>'s opt_bktr.h
1.31 Randall Hopper <rhh@ct.picker.com>
submitted ioctl to clear the video buffer
prior to starting video capture
Amancio : clean up yuv12 so that it does not
affect rgb capture. Basically, fxtv after
capturing in yuv12 mode , switching to rgb
would cause the video capture to be too bright.
1.32 disable inverse gamma function for rgb and yuv
capture. fixed meteor brightness ioctl it now
converts the brightness value from unsigned to
signed.
1.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
hw.bt848.card
card takes a value from 0 to bt848_max_card
tuner takes a value from 0 to bt848_max_tuner
reverse_mute : 0 no effect, 1 reverse tuner
mute function some tuners are wired reversed :(
1.34 reverse mute function for ims turbo card
1.35 Roger Hardiman <roger@cs.strath.ac.uk>
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)
AVerMedia card type added <sos@freebsd.org>
1.39 08/05/98 Roger Hardiman <roger@cs.strath.ac.uk>
Updated Hauppauge detection code for Tuner ID 0x0a
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>
Renamed BT848[SG]CAPAREA to BT848_[SG]CAPAREA.
Added PR kern/7177 for SECAM Video Highway Xtreme
with single crystal PLL configuration
submitted by Vsevolod Lobko <seva@alex-ua.com>.
In kernel configuration file add
options OVERRIDE_CARD=2
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>
Submitted patch by Vsevolod Lobko <seva@alex-ua.com>
to correct SECAM B-Delay and add XUSSR channel set.
1.53 9 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Changed METEORSINPUT for Hauppauge cards with bt878.
Submitted by Fred Templin <templin@erg.sri.com>
Also fixed video_open defines and 878 support.
1.54 18 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Changed tuner code to autodetect tuner i2c address.
Addresses were incorrectly hardcoded.
1.55 21 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Hauppauge Tech Support confirmed all Hauppauge 878
PAL/SECAM boards will use PLL mode.
Added to card probe. Thanks to Ken and Fred.
1.56 21 Jan 1999 Roger Hardiman <roger@cs.strath.ac.uk>
Added detection of Hauppauge IR remote control.
and MSP34xx Audio chip. Fixed i2c read error.
Hauppauge supplied details of new Tuner Types.

Support for MSP3410D / MSP3415D Stereo/Mono audio
using the audio format Auto Detection Mode.
Nicolas Souchu <nsouch@freebsd.org> ported the
msp_read/write/reset functions to smbus/iicbus.
METEOR_INPUT_DEV2 now selects a composite camera on
the SVIDEO port for Johan Larsson<gozer@ludd.luth.se>
For true SVIDEO, use METEOR_INPUT_DEV_SVIDEO
1.58 8 Feb 1999 Roger Hardiman <roger@cs.strath.ac.uk>
Added check to bktr_mmap from OpenBSD driver.
Improved MSP34xx reset for bt848 Hauppauge boards.
Added detection for Bt848a.
Vsevolod Lobko<seva@sevasoft.alex-ua.com> added
more XUSSR channels.

Fix row=0/columns=0 bug. From Randal Hopper<aa8vb@ipass.net>
Add option to block the reset of the MSP34xx audio chip by
adding options BKTR_NO_MSP_RESET to the kernel config file.
This is usefull if you run another operating system
first to initialise the audio chip, then do a soft reboot.
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

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.

*
* The scheme used for probing cards has one major drawback:
* on bt848/849 based cards, it is impossible to work out which type
* of tuner is actually fitted, or if there is extra hardware on board
* connected to GPIO pins (eg radio chips or MSP34xx reset logic)
* The driver cannot tell if the Tuner is PAL,NTSC, Temic or Philips.
*
* All Hauppauge cards have a configuration eeprom which tells us the
* tuner type and other features of the their cards.
* Also, Bt878 based cards (certainly Hauppauge and AverMedia) should support
* sub-system vendor id, identifying the make and model of the card.
*
* 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 849, 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.
