/* BT848 Driver for Brooktree's Bt848 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

directly to a vga frame buffer which has
a linear frame buffer. Minor code clean-up.
1.3 2/23/97 Fixed system lock-up reported by
Randall Hopper <rhh@ct.picker.com>. This
problem seems somehow to be exhibited only
in his system. I changed the setting of
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.

Clipping support added.
1.18 4/23/97 Clean up after failed CAP_SINGLEs where bt
interrupt isn't delivered, and fixed fixing
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
interrupts from a PCI device by default,

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
capture fields for different frames

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.
