Andreas Regel b79c6df705 V4L/DVB (13974): [STV090x] Fix locking reliabilty issues in automatic mode.
In automatic S/S2 detection mode, locking of a DVB-S transponder could
fail when coming from a DVB-S2 transponder. This change fixes the issue
by first disabling DVB-S and DVB-S2 mode before enabling it again.

Abylay Ospan ceb59cf068 V4L/DVB (13936): 22-kHz set_tone fix for NetUP Dual DVB-S2-CI card
22-kHz tone can be driven in two ways:
1. LNBH24 can produce 22kHz continuous tone when TEN=1 ( 22 KHz tone output is
always activated ).
2. LNBH24 can reproduce 22kHz tone timings from DSQIN or EXTM pin's when TEN=0.
From LNBH24 datasheet:
"In order to improve design flexibility an external tone input pin is
available (EXTM). The EXTM is a Logic input pin which activates the 22 kHz
tone output, on the VoTX pin, by using the LNBH24 integrated tone generator
(similar to the DSQIN pin function). In fact, the output tone waveform
characteristics will always be internally controlled by the LNBH24 tone
generator and the EXTM signal will be used as a timing control for DiSEqC tone
data encoding on the VoTX output."

In NetUP Dual DVB-S2-CI card 22kHz tone timings on EXTM pin produced by
STV0900 demod:
.set_tone  = stv0900_set_tone

redefine to "set_tone = lnbp21_set_tone" is not correct for "NetUP Dual
DVB-S2-CI card".

Stefan Richter b2ad41f9ef V4L/DVB (13953): firedtv: add missing NULL pointer check
If there is ever going to be a FireDTV or FloppyDTV firmware which does
not provide a minimal ASCII textual descriptor for Model_Id --- or if
the descriptor is provided indirectly in a descriptor directory ---
the ieee1394 variant of the device probe of firedtv would dereference a
NULL pointer.  The firewire variant of firedtv's device probe is not
affected.

The fix makes sure that such an unexpected firmware is safely recognized
by fdtv_alloc as an unknown firmware.

Devin Heitmueller 6a2071006b V4L/DVB (13930): dib0700: rework IR logic for firmware 1.20
When firmware 1.20 was introduced, the dib0700 switched from a polling model
using a USB control message, to the messages being delivered on a USB bulk
pipe.  The code I originally added would do a blocking read on the pipe with a
50ms timeout.  Because the dvb-usb-remote code makes use of the global
workqueue, this resulted in the global workqueue being blocked 50% of the
time.  Also, the synchronous urb_bulk_msg() call would burn excess CPU time
(reflected as an abnormal increase in the system's load average when devices
were connected).

Rework the logic so that we now setup an asynchronous callback on the bulk
pipe, so that we now only handle RC data when it arrives on the pipe.  Note
that we provide a stub function for the RC polling callback so that we can
continue to leverage the shared code in dvb-usb-rc for the setting up of the
input device.

Andy Walls 5ada57732a V4L/DVB (13910): cx18: Fix set indextable command to properly select I/P/B index entries
The CX18_CPU_SET_INDEXTABLE command was being called with the wrong number
of arguments causing the index table frame type selection mask to be set wrong.
Now the IDX stream properly sends entries for I, P, and B frames.

Andy Walls 82acdc84cc V4L/DVB (13908): cx18: Add initial working VIDIOC_G_ENC_INDEX ioctl() support
VIDIOC_G_ENC_INDEX support see the light of day.
Some notes:
1. With default capture parameters, the CX23418 seems to transfer 192 index
entries (4.5 kB worth) at 10 second intervals.

2. Index streams don't seem to be supported for MPEG 2 TS streams

3. The index entries seem to claim every frame is a B-Frame.  Possible
firmware bug.

4. The cx18 driver does not try to capture an index stream when inserting
sliced VBI into the MPEg stream as the offsets would need fixup.

Andy Walls ef99179710 V4L/DVB (13907): cx18: Perform automatic rotation of very old, unread IDX buffers
According to the v4l2 spec, very old MPEG index entries needs to be discarded
in favor of newer index entries.  This change ensures the firmware always has
buffers for index entries at the expense of the oldest unread buffers.

Andy Walls 79f3e96018 V4L/DVB (13906): cx18: Start IDX streams automatically as an internal associated stream
This change starts the IDX stream along with the MPG stream as an internal
use (only) stream much like the VBI stream can be started as an internal use
stream for inserting sliced VBI packets.

The IDX stream is not started automatically with an MPEG strem if the IDX
stream is disabled (no buffers allocated) or if sliced VBI insertion is being
performed by the cx18 driver.  The cx18 driver doing sliced VBI insertion
makes the offsets in the IDX stream inaccurate for the final MPEG stream
presented to user space.  Since fixing the IDX offsets ourselves is not easy
and we cannot easily do what ivtv does to fix the offsets, we'll make sliced
VBI insertion and MPEG Index capture mutually exclusive for now.

Andy Walls e46c54a87e V4L/DVB (13905): cx18: Allow MPEG index streams to be started and stopped internally
This change allows the IDX stream to be started and stopped as any other
stream even though it has no associated device node.  This is needed for
cx18 driver internal use.

Also always tell the CX23418 to generate index entries when an analog capture
starts and the IDX stream has had buffers allocated (i.e. is enabled).
