2012-08-15[media] rename most media/video usb drivers to media/usbMauro Carvalho Chehab
Rename all USB drivers with their own directory under drivers/media/video into drivers/media/usb and update the building system. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-10-31drivers/media: Add export.h for EXPORT_SYMBOL/THIS_MODULE as requiredPaul Gortmaker
These two macros were in module.h but now module.h is no longer sprayed across every source file imaginable, so the users need to expicitly call out their use of them. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-03-22[media] hdpvr: use same polling interval as other OSJarod Wilson
The hdpvr's IR part, in short, sucks. As observed with a usb traffic sniffer, the Windows software for it uses a polling interval of 405ms. Its still not behaving as well as I'd like even with this change, but this inches us closer and closer to that point...

2011-03-22[media] remove the old RC_MAP_HAUPPAUGE_NEW RC mapMauro Carvalho Chehab
The rc-hauppauge-new map is a messy thing, as it bundles 3 different remote controllers as if they were just one, discarding the address byte. Also, some key maps are wrong. With the conversion to the new rc-core, it is likely that most of the devices won't be working properly, as the i2c driver and the raw decoders are now providing 16 bits for the remote, instead of just 8. delete mode 100644 drivers/media/rc/keymaps/rc-hauppauge-new.c Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Jarod Wilson <jarod@redhat.com>
2011-03-22[media] hdpvr: i2c master enhancementsJarod Wilson
Make the hdpvr's i2c master implementation more closely mirror that of the pvrusb2 driver. Currently makes no significant difference in IR reception behavior with ir-kbd-i2c (i.e., it still sucks).

2011-01-31[media] hdpvr: fix up i2c device registrationJarod Wilson
We have to actually call i2c_new_device() once for each of the rx and tx addresses. Also improve error-handling and device remove i2c cleanup. Reviewed-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-01-19[media] hdpvr: reduce latency of i2c read/write w/recycled bufferJarod Wilson
The current hdpvr code kmalloc's a new buffer for every i2c read and write. Rather than do that, lets allocate a buffer in the driver's device struct and just use that every time. The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128). Note that this might also remedy user reports of very sluggish behavior of IR receive with hdpvr hardware. v2: make sure (len <= (dev->i2c_buf)) [Jean Delvare] Reported-by: Jean Delvare <khali@linux-fr.org> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-01-19[media] hdpvr: enable IR partJarod Wilson
A number of things going on here, but the end result is that the IR part on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or lirc_zilog. First up, there are some conditional build fixes that come into play whether i2c is built-in or modular. Second, we're swapping out i2c_new_probed_device() for i2c_new_device(), as in my testing, probing always fails, but we *know* that all hdpvr devices have a z8 chip at 0x70 and 0x71. Third, we're poking at an i2c address directly without a client, and writing some magic bits to actually turn on this IR part (this could use some improvement in the future). Fourth, some of the i2c_adapter storage has been reworked, as the existing implementation used to lead to an oops following i2c changes c. 2.6.31. Earlier editions of this patch have been floating around the 'net for a while, including being patched into Fedora kernels, and they *do* work. This specific version isn't yet tested, beyond loading ir-kbd-i2c and confirming that it does bind to the RX address of the hdpvr. [mchehab@redhat.com: I2C_CLASS_TV_ANALOG is not defined.

2010-12-30[media] hdpvr: Add I2C and ir-kdb-i2c registration of the Zilog Z8 IR chipAndy Walls
Adds I2C registration of the Zilog Z8F0811 IR microcontroller for either lirc_zilog or ir-kbd-i2c to use. This is a required step in removing lirc_zilog's use of the deprecated struct i2c_adapter.id field.

2010-10-21[media] i2c: Stop using I2C_CLASS_TV_ANALOGJean Delvare
Detection class I2C_CLASS_TV_ANALOG is set by a few adapters but no I2C device driver is setting it anymore, which means it can be dropped. I2C devices on analog 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 Heo
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.

2009-03-30V4L/DVB (11096): V4L2 Driver for the Hauppauge HD PVR usb capture deviceJanne Grunau
The device encodes component video up to 1080i to a MPEG-TS stream with H.264 video and stereo AAC audio. Newer firmwares accept also AC3 (up to 5.1) audio over optical SPDIF without reencoding. Firmware upgrade is unimplemeted but rather unimportant since the firmware sits on a flash chip. The I2C adapter to drive the integrated infrared receiver/sender is currently disabled due to a conflict with cx18-based devices.
