(tested on 2.4.18 and 2.5.53 -- the budget driver is
untested, Holger will test it the next week)
saa7146:
- completely separated the saa7146 driver into a core-driver (saa7146.o) and
a video/vbi part (saa7146_vv.o). this allows you to build the budget driver
without av7110 and videodev bloat (see below)
The following thinks have been approved by Holger Waechtler:
av7110 (now ttpci):
- for 2.5.x: removed the av7110 directory and put everything into ttpci.
- removed all budget card support from this driver
- compile and build fixes for the saa7146 changes
ttpci-budget (new):
- for 2.5.x: created a new ttpci-budget directory, added a new driver for
the budget cards
mxb:
- compile and build fixes for the saa7146 changes
Changed the build and compile files for both 2.5.x and build-2.4 of course...

videodev.o dependency,
so we can later split up the av7110 driver into a av7110 and budget card driver.
I tested this on 2.4.18-3 (original RedHat 7.3 kernel) and 2.5.53.
Changes in detail:
saa7146:
- fixed the unitialised timer warnings
- split saa7146.o into saa7146.o and saa7146_vv.o:
all videodev (ie. v4l) related stuff is now encapsulated in saa7146_vv.o.
the extension (ie. mxb or dvb-ttpci) now has to make sure to register the v4l
devices via helper functions provided by saa7146_vv
mxb:
- changes to make the driver compile with the new saa7146 and saa7146_vv parts
- fix the vbi bypass issue for MXBs with saa7146, rev. 1 card
av7110:
- changes to make the driver compile with the new saa7146 and saa7146_vv parts
- some changes related to the upcoming av7110 <=> budget splitup, but they are
commented out
- changed the saa7146 PAL values to experimental values that look good to me, but
kept the old values as a comment. where are the original values from? there is
a big black border on most channels on the left side which annoyed me...
- changed from video/generic_usercopy() to dvb_usercopy() and put this into the
source code, not into compat.c
- moved the crc_32* stuff from compat.c to the source file where it is used
- now compat.[ch] was removed completely, all references were deleted from
all other files.
other:
- updated the README and TODO files
- changed "makelinks" to remove alps_bsru6 stuff from kernel when making the symlinks
- fixed the build files in "build-2.4"
- fixed all other files needed for 2.5.x kernel build

obviously bogus dmapos values.

SAA7146 does not generate an I2C error irq when we are probing
for a non-existant device (so there's neither an ACK nor a NACK
at the end of the address phase)
- don't request the I2C error irq anymore, since it isn't currently
being handled; we just wait for the /BUSY irq or timeout; if there
were errors during transmission they will still be detected
from the status register after the /BUSY irq
- added some more debug to hw_interrupt()
TODO: I think SAA7146_I2C_TIMEOUT is too large; 10ms should do?

driver. I doesn't do any harm for my analog drivers and apparently fixes some
bugs related to some frontends/tuners, who expect certain start/stop cycles.
Please check if these tuners work now...

(ie. the av7110) handle the odd/even fields differently. I added a new
field to the extension, which holds special flags of the extension and the
device. I declared the MXB way of handling fields as "normal", so the
av7110 extension sets SAA7146_EXT_SWAP_ODD_EVEN here.
@Holger: I added some superfluous "struct saa7146_dev *dev" variables
back to some functions. These cause ugly warnings at compile time, I admit,
but they are necessary if you want to use the debug macros to trace a
saa7146 register for example. Please leave them in for now -- I need this
when I switch between old-DVB / old-MXB <=> new-DVB / new-MXB drivers and
try to hack out the differences.

possible to create a complete call trace now.
(You can #if 0 this out, if you are concerned about runtime
drawbacks...)

copy & paste error), removed duplicate dvb_register_i2c_bus() call,
removed all references to RPS0, it's not used at all. (this fixes
the capturing problems)

instead of busy waiting for an i2c transaction to finish. Left the
old method in there. if you need it (or if i screwed up),
set "use_i2c_irq" to zero in saa7146_i2c.c to get the old behaviour.

exported. Holger, you made a change a few days ago, introducing
av7110_ipack.c and this. If this is intended, you should
give it a new name with the "dvb" prefix.

- use const pointers in section and ts callbacks
