2012-08-13[media] Rename media/dvb as media/pciMauro Carvalho Chehab1-1246/+0
The remaining dvb drivers are pci, so rename them to match the bus. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] dvb: earth-pt1: remove unsupported net subdevicesAkihiro Tsukada1-4/+0
PT1 and PT2 do not have net functions. Signed-off-by: Akihiro Tsukada <tskd2@yahoo.co.jp> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] dvb: earth-pt1: decrease the too large DMA buffer sizeAkihiro Tsukada1-1/+1
Current default value of "nr_tables" option corresponds to the DMA buffer of about 10 to 48 seconds long, which is obviously too much. Signed-off-by: Akihiro Tsukada <tskd2@yahoo.co.jp> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] dvb: earth-pt1: add an error check/report on the incoming dataAkihiro Tsukada1-0/+14
This patch adds a data integrity check using the sequence counter and error flags added by the bridge chip. Signed-off-by: Akihiro Tsukada <tskd2@yahoo.co.jp> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] dvb: earth-pt1: stop polling data when no one accesses the deviceAkihiro Tsukada1-23/+50
The driver started a kthread to poll the DMA buffers soon after probing, which relsuleted in 1000/sec sleeps and wakeups of the thread doing nothing useful until someone started feeding. This patch changes the creation and destruction of the kthread depending on the number of users.

2010-10-21[media] i2c: Stop using I2C_CLASS_TV_DIGITALJean Delvare1-1/+0
Detection class I2C_CLASS_TV_DIGITAL is set by many adapters but no I2C device driver is setting it anymore, which means it can be dropped. I2C devices on digital TV adapters are instantiated explicitly these days, which is much better.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+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.

2009-09-19V4L/DVB (12999): Add a driver for Earthsoft PT1Mauro Carvalho Chehab1-0/+1056
Add a driver for Earthsoft PT1 Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S and ISDB-T demodulators. This card has neither MPEG decoder nor conditional access module onboard. It transmits only compressed and possibly encrypted MPEG data over the PCI bus, so you need an external software decoder and a decrypter to watch TV on your computer. This driver is originally developed by Tomoaki Ishikawa <tomy@users.sourceforge.jp> by reverse engineering.
