The commands to start / stop USB streaming for an analog device are fairly standard, owing to the fact that all supported devices apparently started from the same common reference design. However with digital mode, the commands seem to vary by vendor. This change makes that variance more explicit. It also cleans up a related problem for OnAir devices which prevented digital mode from working at all. Signed-off-by:

Numerous places in the driver need to issue simple commands to the FX2 microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously each place that did this, had to take lock, set up a central buffer, and call the function to perform the handshake. This change puts these steps into a single spot. This also has the effect of removing the need to mess with the control lock from numerous places in the code. Signed-off-by:

Implement a mechanism in the pvrusb2 driver for gathering statistics on the stream buffering, including bytes transferred, buffers handled, buffers in flight, etc. This is useful for debugging certain classes of streaming issues and for determining if the buffer pool size is generally correct for the driver.

Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's really private to the pvrusb2-dvb module and nothing outside of the dvb implementation should care about it. Creation / destruction of the pvr2_dvb_adapter instance is now contained entirely within pvrusb2-dvb.c. Signed-off-by:

In the end we'd like the dvb interface to always be present - even for analog devices (via the mpeg encoder). However right now pvrusb2-dvb won't operate correctly if the hardware doesn't have a digital tuner, so don't initialize the DVB interface unless we know we have a digital tuner. Signed-off-by:

Other pvrusb2-dvb changes have made the digital_up flag obsolete. So kill it. Signed-off-by:

Rather than making an explicit call to tear down the pvrusb2-dvb module, use the callback in the pvr2_channel structure. This has the advantage that now tear-down only happens when it makes sense. The previous implementation had scenarios where it was possible for the tear-down call to happen without a prior initialization. Signed-off-by:

Eliminate the need for a separate pvr2_dvb_fh; since in the DVB context there can only ever be a single instance then there is no need for a separate instance to handle streaming state. This simplifies the module. Also move streaming start/stop out of the feed thread and into the driver's main context - which makes it possible for streaming start up failures to be detected by the DVB core. Signed-off-by:

The pvrusb2-dvb feed thread cannot be allowed to exit by itself without first waiting for kthread_should_stop() to return true. Otherwise the driver will have a dangling task_struct context, which will cause a very nasty kernel oops. Signed-off-by:

Add basic framework for the DVB API. This is enough to control the tuner & demod of the digital frontend, but the stream & buffer handling is still missing. Additional note from Mike Isely <isely@pobox.com> - also, since these changes are still very experimental arrange for DVB changes to be compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.

Currently the pxa-camera driver has a bug, visible when the user requests more than 2 video buffers. When the third buffer is queued, it is not appended to the DMA-descriptor list of the second buffer, but is again appended to the first buffer. Fix it. Signed-off-by:
