* Use 'agc' instead of 'autogain' in the code so to align the naming

  * Tweak brightness and contrast default values.
  * Fix setting/resetting registers values for AGC.
  * Set actual gain back when disabling AGC.
  * Skip setting GAIN register when AGC is enabled.
  * Enable AGC by default.

Note that as Auto Gain Control is now enabled by default, if you are
using the driver for visual computing applications you might need to
disable it explicitly in your software.

Imho not a good idea, as the frontend thread calls

- fe->ops.tuner_ops.sleep

If you remove fe->ops.i2c_gate_ctrl, init and sleep will fail,
because gate_ctrl was never called...

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.

When power management is not configured (CONFIG_PM) then some code is no longer
necessary.

This patch will remove the following compiler warnings:
 * pd-dvb.c: In function 'poseidon_fe_release':
 * pd-dvb.c:101: warning: unused variable 'pd'
 * pd-video.c:14: warning: 'pm_video_suspend' declared 'static' but never defined
 * pd-video.c:15: warning: 'pm_video_resume' declared 'static' but never defined

Marton Balint d044189dfe V4L/DVB: cx88: increase BUFFER_TIMEOUT to 2 seconds
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.

Devin Heitmueller b628a2a3d4 V4L/DVB: au8522: fix case where we don't perform the first tune after going digital
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.

Thanks to Zaphod Beeblebrox for reporting this issue.

Devin Heitmueller 7f2c983cf5 V4L/DVB: au8522: fix race condition in switching from digital to analog mode
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.

Thanks to Zaphod Beeblebrox for reporting this issue.

Valentin Longchamp 535653b1c2 V4L/DVB: mt9t031: use runtime pm support to restore ADDRESS_MODE registers
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.
