[pxc] AGC on generic Bt and/or PXC200*

[Marius van Wyk]

How do I disable the Auto Gain Control (AGC) on my card?
(At the moment a generic Bt 878)

I've figured out that it is bit 6 on the SCLOOP register pair, and am 
assuming that I only have to switch it off.

Is there any way which I can control this from my program via ioctl calls?

Else I may need to rey and modify the driver, but am not sure where to code 
it in... (for instance when the card get's reset, I may need to clear it 
again etc.)

Any help wrt. this?

My application is such that I switch between different cameras faster  than 
the AGC can adapt, and I control the video 
level/saturation/brightness/contrast manually and explicitly. The AGC is 
only screwing things up.

Is there perhaps A WAY?
:)

Marius.
