YCbCr 422 on s3c2440

[GIGIN JOSE]

Hi, 

I am working on s3c2440 ARM linux platform. I am connecting 
an image sensor device to the camera controller of the s3c2440 
ARM processor. The image sensor outputs YCbCr 4:2:2 output. 
Can I pass the output of this format to the preview path of 
the camera controller to get proper image ? 

The image sensor also outputs RGB565 format, which I can 
comfortably view using the preview path. But I would like 
to get the YCbCr 4:2:2 format from the image sensor device. 

Is this possible with the preview path ? Any other register
 settings are required for YCbCr 4:2:2 mode on the preview 
path, other than that done for the RGB565 format. ?

Thank You
