Visstrim_M10 have a tvp5150 whose video output must be deinterlaced. The new mem2mem deinterlacing driver is very useful for that purpose. Signed-off-by:

Some video decoders such as tvp5150 provide separate video fields (V4L2_FIELD_SEQ_TB/BT). This driver uses dmaengine to convert this format to V4L2_FIELD_INTERLACED_TB/BT (weaving) or V4L2_FIELD_NONE (line doubling) so that the image can be displayed or processed. Of course there will be combing effect in the image but this can be accepted for some low quality applications. Currently only YUV420 and YUYV formats are supported but it can be extended later.

Coda is a range of video codecs from Chips&Media that support H.264, H.263, MPEG4 and other video standards. Currently only support for the codadx6 included in the i.MX27 SoC is added. H.264 and MPEG4 video encoding are the only supported capabilities by now. [mchehab@redhat.com: Add missing include linux/of.h] Signed-off-by:

While this header were meant to be used just by dvb-usb driver, it is now being used also by dvb-usb-v2 and cx231xx. So, move it to a better place. Signed-off-by:

1) AF9015 remote controller query will fail rarely due to register access failures and dvb_usb_v2 will stop rc polling when error returned. Add logic to allow errors until two consecutive errors occurs. 2) Remote controller key map was not loaded in case of key map was set as a device property. Fix it. Signed-off-by:

It failed to register device when remote keymap was not set. Fix it to register device even keymap is NULL. In that case just skip remote registration. Driver should set RC_MAP_EMPTY to enable remote in case of there is remote receiver but default keymap is unknown. Reported-by:

It works no longer as it was designed since we can change streaming configuration during device operation. Maybe it should be performed conditionally on cases when streaming endpoint is changed. Anyhow, let it out now and add later if needed. Signed-off-by:

It is nice to have this debug, but as it generates very huge amount of traffic, better to make it conditional. Use define macro to disable it as I did not find out how to use dynamic debugs to dump variable length buffers like that. Signed-off-by:

Merge get_firmware_name() to identify_state(). It is wise to resolve firmware name in that routine as it does decision wether or not to load firmware at all. It is one very rarely needed callback less. Signed-off-by:

Piggypag TS type callback to USB stream callback and change callback name slightly to fit better. Both of those are rather rare callback and has a relation. Transport Stream, TS, is input stream and USB stream is output stream of DVB USB bridge. Signed-off-by:

There was synchronization problem when streaming was stopped. Frontend was ran down before stream which causes problems. Use mutex to synchronization. Now it looks like that: LOCK start frontend UNLOCK LOCK start streaming [...] stop streaming UNLOCK LOCK stop frontend UNLOCK Signed-off-by:
