When a capture is started, the firmware also appears to start a secondary
stream. Unless this secondary stream is also stopped, the encoder will remain
active and not reinitialise for the next capture. Unfortunately, setting up
the video source can glitch the encoder and result in undesirable effects that
this initialisation will clear.

Combine the two 150 ms delays into a single 300 ms delay. Ian Armstrong has
noted that the delay between CX2341X_ENC_INITIALIZE_INPUT and
CX2341X_ENC_START_CAPTURE can cause problems if the temporal filter is allowed
to be enabled.

linux-media mailing list on 8/14/09, to the current sources in order
to make the Kworld VS-DVB-T 323UR usb device work.
I also removed the "not validated" flag since I own the device and validated
that it works fine after the patch is applied.

When temporarily there is no video signal, sometimes it takes more than 0.5
secs for the cx88 chip to generate a single frame. If a dma timeout occurs
during recording, it confuses the recording application (at least mencoder)
and the recording stops.
Since there is already an #if 0 for 2 seconds buffer timeout in the code
at the -hg development tree, re-enabling that seemed the most simple
solution.

Address a problem found in MythTV where if we are in digital mode, switch to
analog mode, and the switch back to digital mode, the first tuning request
after switching back to digital mode gets dropped. This is because the au8522
maintains internal state, and would think the demod was already tuned to the
target frequency.

With applications like MythTV, switching inputs results in closing the digital
side and then immediately opening the analog side. This exposes a race
condition where the dvb_frontend kernel thread powers down the chip and closes
the i2c gate even though we're in the middle of bringing up the analog part
of the chip (since the shutdown of the dvb_frontend kernel thread occurs
asychronously).
Introduce a construct to keep track of what mode we're in, and drop requests
to power down or management the gate if we've already switched to analog mode.

If the platform hooks are provided, soc_camera powers off the device
on close and powers it on on open. This resets the ADDRESS_MODE registers
which then can be different to the value the driver has computed for them.
This patch setups runtime pm usage for mt9t031 and uses the resume function
to write the ADDRESS_MODE registers in order to fix the above described
problem.

To save power soc-camera powers subdevices down, when they are not in use,
if this is supported by the platform. However, the V4L standard dictates,
that video nodes shall preserve configuration between uses. This requires
runtime power management, which is implemented by this patch. It allows
subdevice drivers to specify their runtime power-management methods, by
assigning a type to the video device.

An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.
Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.
The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.
