Due to several internal API changes on kernel, kernel backward
compatibility were lost. Basically, compat.h should be the last include
for it to work properly.
This patch basically reorders kernel headers to allow backward compat to
work fine.
Also:
Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files.

If the SAA7111 device is powered down, and requires re-initialisation when
the V4L device is opened (as on the NetWinder), the SAA7111 driver gets
completely confused about the current settings.
The problem is centred around the way the driver keeps _two_ cached copies
of the current settings - one of the struct video_picture settings, and one
of the registers.
When the decoder is re-initailised, the cached register settings are
overwritten, as are the values in the hardware registers. However, the
cached video_picture settings are not.
Resolve this by removing the useless and buggy second level of caching for
video_picture. Instead, provide a function which updates register values
if and only if the value we are going to write to the register has changed.

Now, drivers/media tree is complete. Only missing zoran36120
since this won't work and it is a good candidate to be removed
from kernel soon.

ongoing i2c changes in 2.5. Because of the fact that they are already
in the kernel and won't change any more, they can be removed here
and added to the build-2.4 directory.

less dependent on the linux kernel. here is the place to store
additional dvb_* functions, which encapsulate linux kernel functionality
which cannot be expressed as a one-liner
- rename ddelay() to dvb_delay(), move it to dvb_functions.h
- change all files to include dvb_functions.h instead of dvb_compat.h
- compile fix for the saa7111 driver
|
|
- add some ifdef magic into i2c drivers (mxb/analog drivers only)
- shuffle around includes, so that "dvb_compat.h" is included after
all other include files
- fix a warning in saa7146 i2c code
|
|
2.5. Add the DVB_DEVFS_ONLY switch back again.
|
|
mxb: prevent helper modules to probe on unknown i2c-busses. (for example on a
Matrox gfx card)
|
|
- removed the patches, they are not needed any more. you can now
use a vanilla 2.5.55 kernel
- created a new backport for video-buf and videodev from the 2.5.55
sources
- necessary fixes to the saa7146 driver due to changes in 2.5.55
- the core budget functions are now provided by a module called
"budget-core.o". (otherwise static compilation is not possible...)
- removed #ifdef MODULE crap from all files
Misc.
- "xawtv" (using xv extension) resulted in wrong colors. the problem
is within "xawtv". Gerd Knorr told me, that it'll be fixed in the
next release.
I tested this version with 2.4.20, 2.5.55 (modules) and 2.5.55
(static).

READMEs accordingly, compile fixes for the mxb driver.
|
|
for the new saa7146 core, the mxb driver and the saa7111 driver.
|
|
an analogue tv card based on the saa7146.
Warning: Makefile and Kconfig will most likely be changed by
Gerd Knorr as well, so be sure to change these accordingly.
Warning2: "saa7111" is already available in the kernel, but needs
to be modified, as well as "video_decoder" in include/linux
