Add a module parameter to adjust I2C SCL clock period per board. This allows some experimental fine tuning by end users to overcome quirky I2C device problems. Reported-by:

The encoder was not honoring the MDL size sent in DE_SET_MDL mailbox commands. This change adjusts the size of the last buffer in an MDL, as reported to the firmware, so that the encoder will send the exact amount of bytes we specify per MDL transfer. This eliminates tearing in YUV playback when using non-default YUV buffer sizes. Signed-off-by:

Fix YUV capture such that the encoder will pass one frame per transfer. This will allow the application to maintain frame alignment when a transfer from the encoder is missed due to high system latency in service the CX23418 IRQ. Also force YUV buffer sizes to be specified in multiples of 33.75 kB, the smalled amount of buffer sizes need to store a complete set of HM12 4:2:0 macroblocks specifying 32 lines of the frame. A full 60Hz/525 line screen requires 15 * 33.75 kB per frame and a full 50Hz/625 line screen requires 18 * 33.75 kB per frame so the default buffer size is 3 * 33.75 kB, requiring exactly 5 or 6 buffers per MDL respectively. The bytes needed per frame and hence MDL need not be the bytes in an integer number of buffers. However, if frame artifacts are seen with scaled screen sizes, the YUV buffer size can be set 34 kB (33.75 kB) to get rid of the artifacts at the cost of more copies between the kernel and userspace.

Add debug register write interface to pac7302 to be able to set for example the edge detect mode (bit 2 register 0x55) or the test pattern (bit 0..3, register 0x72) and test overlay (bit 4, register 0x72) from the user space. Only write of register page 0 is supported by this patch. Signed-off-by: Márton NÃ

For whatever reason, the device structure pointer to videobuf_queue_vmalloc_init is typed "void *", even though it's passed right through to videobuf_queue_core_init(), which expects a struct device pointer. The other videobuf implementations use struct device *; I think vmalloc should too. Signed-off-by:

Packet DMA buffers are queued either initially all at once (then, a queueing failure will cause firedtv to release the DMA context as a whole) or subsequently one by one as they recycled after use (then a failure is extremely unlikely). Therefore we can be a little less cautious when counting at which packet buffer to set the interrupt flag. Signed-off-by:

The firedtv DVB driver will now work not only on top of the old ieee1394 driver stack but also on the new firewire driver stack. Alongside to the firedtv-1394.c backend for driver binding and I/O, the firedtv-fw.c backend is added. Depending on which of the two 1394 stacks is configured, one or the other or both backends will be built into the firedtv driver. This has been tested with a DVB-T and a DVB-C box on x86-64 and x86-32 together with a few different controllers (Agere FW323, a NEC chip, TI TSB82AA2, TSB43AB22/A, VIA VT6306). Signed-off-by:

Add #include <dvb_demux.h> for dvb_dmx_swfilter_packets(). This was already indirectly included via firedtv.h, but don't rely on it. The 4 bytes which were referred to as FIREWIRE_HEADER_SIZE are actually the source packet header from IEC 61883-4 (MPEG2-TS data transmission over 1394), not e.g. the IEEE 1394 isochronous packet header. So choose a more precise name. Also, express the payload size as a preprocessor constant too. Signed-off-by:

This initialization of the value of audio_mode is the one used if nothing matches in the subsequent switch. The variable audio_mode is subsequently assigned to constants such as TUNER_AUDIO_MONO and TUNER_AUDIO_STEREO. TUNER_AUDIO_STEREO has the same value as V4L2_TUNER_MODE_STEREO, so it would seem better to use that value here. Signed-off-by:
