From: Jean-François Moine <[email protected]>
The exchanges relative to the light frequency filter were adapted
from a description found in a ms-windows driver. It seems that the
registers were the ones of some other sensor.
This patch was done thanks to the documentation of the right
OmniVision sensors.
Note: The light frequency filter is either off or automatic.
The application will see either off or "50Hz" only.
