V4L/DVB: ivtv: Adjust msleep() delays used to prevent tinny audio and PCI bus hang

Martin Dauskardt <martin.dauskardt@gmx.de> has done extensive testing on what
values can be used and and concluded that only 300 ms total is required to
avoid bad video effects such as occasional black screen and short sync
disturbances.  Furthermore he determined how this 300 ms was split between
the two msleep()s did matter very much, so he suggested 150ms/150ms as one
acceptable alternative that is implemented here.

Many thanks go to Martin.

V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny audio

This change attempts to fix the ivtv tinny audio problem by keeping digitizer
to encoder audio clocks running, while disabling the video clocks as needed to
avoid unpredictable PCI bus hangs.

To accomplish this, for the cx25840 module enabling of audio streaming had
to be separated from enabling video streaming, requiring an additional
v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers.

The cx231xx and cx23885 driver use the cx25840 module for affecting only
video on s_stream calls, so those drivers needed no change.

The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI
bus hang, so the cx18 driver did not need corresponding changes.

CX2341[56] based cards that are not using the CX2584x family of chips
do not seem to be affected by the tinny audio problem, and this change should
not affect how they are configured. It will delay their first capture by
starting by another 300 msec though.

Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and
Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and
investigation of this problem will hopefully fix this problem once and for all
for many ivtv users.

V4L/DVB: ivtv: Fix race condition for queued udma transfers

There are several DMA related interrupts which wake up the dma_waitq. The udma
routines use this queue while they wait for their transfer to complete. When
woken, the udma routine will check the IVTV_F_I_UDMA_PENDING & IVTV_F_I_UDMA
flags to see if the transfer is still queued or has finished. However, a small
window exists between the IVTV_F_I_UDMA_PENDING flag being cleared and the
IVTV_F_I_UDMA flag being set. Given that the completion of an unrelated DMA
transfer may wake up the udma routine, it's possible for this check to fail
and the udma routine will start unmapping pages when the transfer has only
just started. The result of this is unpredictable.

This fix simply delays the clearing of the IVTV_F_I_UDMA_PENDING flag until
after IVTV_F_I_UDMA has been set.

V4L/DVB: 22-kHz set_tone fix for NetUP Dual DVB-S2-CI card. 22kHz logic controlled by demod

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

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

but it is dereferenced earlier. Move the dereference after the
check.
