Hi Oliver,

Just to be clear.  You mean fixing the loading issues(ugly msleep, 
etc...) that Mauro mentioned, not the YUV formats(which seem unrelated)? 

Would it be ok to have just 422P and greyscale in the driver for now if 
we can't get a firmware update in a reasonable timeframe? It's certainly 
not ideal, but we could direct our customers to the libraries, at least 
until we get a proper HW fix.

Best regards,

Dean
