* V4L/DVB: mt9v011: add enum/try/s_mbus_fmt supportHans Verkuil2010-06-011-20/+17
| | | | | | | | | | | | Note that this driver is only used by em28xx and that em28xx does not actually call the enum/try/s_fmt ops of mt9v011. So these functions have never been tested. And in fact the driver really implements cropping instead of scaling. So it seems to be doing the wrong thing :-( Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* V4L/DVB (12340): mtv9v011: Add a missing chip version to the driverMauro Carvalho Chehab2009-08-131-5/+9
| | | | | | | | | | | Some mt9v011 webcams report 0x8332 chip version, instead of 0x8243. From the revision history at the mt9v011 datasheet, it seems that the chip version has changed from the first release of the chip. Thanks-to hermann pitton <hermann-pitton@arcor.de> for pointing this to me, on his tests with a Silvercrest webcam. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (12240): mt9v011: add a function to calculate frames per second rateMauro Carvalho Chehab2009-07-241-1/+31
| | | | | | | | | | | It is possible to adjust the fps rate by changing some register values. This is function of the connected Xtal at the camera sensor, being a 27 MHz cristal needed, in order to support 640x480 at 30 fps. For now, it will only calculate the values for fps. Later patches may introduce V4L2 ioctls, to allow frequency rate adjustments. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (12174): mt9v011: let's stick with datasheet values where it worksMauro Carvalho Chehab2009-07-051-16/+7
| | | | | | | | | | | The original driver for Silvercrest cameras were using some values that are different from what datasheet says. As result, it was taken very less snapshots per second than expected. A test with the datasheet values showed that they work fine and give a better frame rate. So, let's stick with datasheet values.

* V4L/DVB (12173): mt9v011: properly calculate image resolution registersMauro Carvalho Chehab2009-07-051-20/+94
| | | | | | | | | | | | | | Instead of working with a table of precalculated values, fill them with the proper values. Also, adds format functions that allow changing the resolution, by cropping the image to the center of the sensor. While here, move the sensor version check to the probe routine, to indicate to the caller if the sensor is not supported by this driver. Also, fixes a stupid bug where we're using &buffer[] instead of buffer[]. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
