Is it possible to set a frame buffer driver to YUV color mode?

Hello,

We are using /dev/fb0 for analog display on a OMAP3730 and linux kernel 3.0.xx.  Right now, /dev/fb0 is configured to accept frames in RGB color space, but we do our video processing in the YUV colorspace.  Is there a way to configure /dev/fb0 to accept images in the YUV color space, either by the fbset utility or a sysfs entry?  (We would like to avoid a YUV->RGB conversion if possible). 

Here is the output of fbset -s:

mode "720x482-30"
    geometry 720 482 720 482 32
    timings 74074 58 16 31 6 64 6
    accel false
    rgba 8/16,8/8,8/0,0/0
endmode

Thanks in advance.
