Bruce Evans 084d9853ca Don't declare isa device structs or isa interrupt handlers in <sys/conf>,
and don't depend on them being declared there.  This will cause lots of
warnings for a few minutes until config is updated.  Interrupt handlers
should never have been configured by config, and the machine generated
declarations get in the way of changing the arg type from int to void *.

-------------------------------------------------------------------------------
Recent versions of 3.0-current have the bktr driver built in.  Older versions
of 3.0 and all versions of 2.2 need to have the driver files installed by hand:

cp ioctl_bt848.h /sys/i386/include/
cp brktree_reg.h brooktree848.c /sys/pci/

In /sys/conf/files add:
pci/brooktree848.c        optional bktr device-driver

-------------------------------------------------------------------------------
In all cases you will need to add the driver to your kernel:

In your kernel configuration file:
controller      pci0     #if you already have this line don't add it.
device          bktr0    

There is no need to specify DMA channels nor interrupts for this
driver.

-------------------------------------------------------------------------------
Finally you need to create nodes for the driver:

Create a video device:
mknod /dev/bktr0 c 92 0

Create a tuner device:
mknod /dev/tuner0 c 92 16

-------------------------------------------------------------------------------
The code attempts to auto-probe code to detect card/tuner types.
The detected card is printed in the dmesg as the driver is loaded.  If
this fails to detect the proper card you can override it in brooktree848.c:

#define OVERRIDE_CARD	<card type>

where <card type> is one of:
	CARD_UNKNOWN
	CARD_MIRO
	CARD_HAUPPAUGE
	CARD_STB
	CARD_INTEL

-------------------------------------------------------------------------------
This model now separates the "tuner control" items into a minor device:

minor device layout:  xxxxxxxx xxxT UUUU

 UUUU:   the card (ie UNIT) identifier, 0 thru 15
 T == 0: video device
 T == 1: tuner device

Access your tuner ioctl thru your tuner device handle and anything
which controls the video capture process thru the video device handle.

Certain ioctl()s such as video source are available thru both devices.

-------------------------------------------------------------------------------
If your tuner does not work properly or is not recognized properly
try setting the tuner type via or card type:
sysctl -w hw.bt848.card=<integer> current valid values are 0 to 5 inclusive
sysctl -w hw.bt848.tuner=<integer> where integer is a value from 1 to 10
systcl -w hw.bt848.reverse_mute=<1 | 0> to reverse the mute function in the
                                driver set variable to 1.
The exact format of the sysctl bt848 variable is:
unit << 8 | value

unit identifies the pci bt848 board to be affected 0 is the first bt848 
board, 1 is the second bt848 board.
value denotes the integer value for tuners is a value from 0 to 10 for
reversing the mute function of the tuner the value is 1 or 0.

to find out all the bt848 variables:
sysctl hw.bt848



-------------------------------------------------------------------------------
The bt848 driver consists of:

src/sys/i386/include/ioctl_bt848.h
src/sys/pci/brktree_reg.h
src/sys/pci/brooktree848.c
