2009-03-30v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Originally the intention was to switch to the new style i2c API starting with the introduction of the API in 2.6.22. However, the i2c_new_probed_device() function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately, it was only fixed in the stable series of 2.6.25 and 2.6.26. Given the fact that the new i2c API also changed starting with 2.6.26 (the addition of i2c_device_id), it is easiest to switch APIs starting with 2.6.26. This patch updates all the legacy code accordingly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2008-11-25fix boards for kernels with algo_controlMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> changeset 4ecae6da8244 removed algo_control from i2c drivers. However, on older kernels, a dummy function to implement algo_control is required, otherwise, an OOPS is generated. This patch adds a backport for all i2c drivers that defines an i2c_algorithm, except for cafe_ccic, since OLPC hardware only works for kernels newer than 2.6.19. Some of the backported drivers would need also extra changes to work with older kernels, as specified on v4l/versions.txt. Yet, I decided to add the backport for those drivers also, since the lack of algo_control doesn't generate any compilation error, but it is enough to break the driver. So, better to all for all boards than to allow compiling a kernel backported that just generates OOPS. Priority: normal Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-04-26From: Mauro Carvalho Chehab <mchehab@infradead.org>Mauro Carvalho Chehab
Move tuners to common/tuners There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. This patch moves those common tuners into a common dir. It also moves saa7146 driver into drivers/media/video, where other hybrid drivers are placed. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-02-19compat: Add -include linux/version.h to cflagsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add -include linux/version.h to the cflags. Now code can have backward compatibility test without including compat.h first. Linux headers included from compat.h are removed, so that code will get the same headers when compiling in v4l-dvb as it does in the kernel. Many drivers have compat.h moved to the end of their include list, as this lets compat.h do things it can't do at the beginning. Such as test of something is defined to include compat code, or to put a wrapper around a function without changing the function's name. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2005-10-01[PATCH] I2C: Kill i2c_algorithm.name (1/7)Michael Krufky
The name member of the i2c_algorithm is never used, although all drivers conscientiously fill it. We can drop it completely, this structure doesn't need to have a name. [PATCH] I2C: Kill i2c_algorithm.id (4/7) There are no more users of i2c_algorithm.id, so we can finally drop this structure member. [PATCH] I2C: Kill i2c_algorithm.id (6/7) In theory, there should be no more users of I2C_ALGO_* at this point. However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id. We are really lucky that the few other adapters we want this driver to work with did not fulfill that condition.

2003-06-14i2c fixes and build fixes. Must have been brain-amputated yesterday...Holger Waechtler
2003-05-28I removed all "analog" drivers from the main CVS repository and moved themMichael Hunold
to a separate "analog-2.4" directory. Main reasons: - the drivers don't have anything to do with dvb 8-) - the drivers are already in the kernel (besides the "Hexium" driver) and don't change that much any more - the analog drivers rely on the i2c subsystem, which was heavily modified between 2.4 and 2.5. When making a new DVB patchset I have to work around these differences every time, which is very annoying
2003-05-19First try to use pci_consistent_dma() throughout the whole saa7146Michael Hunold
driver subsystem.
2003-04-28Compile fixes against 2.5.68.Michael Hunold
- 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
2003-04-22- removed the compatibility crap around KBUILD_MODNAME from all drivers,Michael Hunold
use KBUILD_BASENAME for 2.4 instead ­ some changes to the i2c core to make it work with both 2.4 and late 2.5 kernels (not done yet -- only interesting for analog drivers) - add MODULE_DEVICE_TABLE to all drivers, so that pci "hotplug" can detect the devices automatically. Alan Cox says, that we should use this to load the firmware (not done yet) - fix the long standing "insmod/rmmod with multiple budget cards" bug -- it was a double kfree() call...
2003-03-20This is the beginning of some modifications to get the newMichael Hunold
"dvb-kernel" tree into shape for direct inclusion into the 2.5.x kernel.

- clean up the mxb driver and it's helper modules (rename the structures, add GPL license to the appropriate files, c99 initialisers) - fix 2.5.55 "module insertion causes bug in kobject.o" issue - fixed missing exported symbols in budget-core
2003-01-09return meaningful error valuesHolger Waechtler
2003-01-05After all, using the i2c irq wasn't a good idea. After long hours ofMichael Hunold
testing why the !#+?§"1 TS stream stops and "debi oops" messages appear, I found out that this is caused by the i2c irq handler. Don't ask me why, but returning to the old code solved this mystery. Apparently, the additional i2c interrupts caused some timing problems or the saa7146 is simply too f*cked up. I left the code in however, it works for the analog MXB driver, so the extension should decide if it should be used. Removed some additional debug messages, which were commented out anyway.
