i.MX Framebuffer queries

I'm using a mx53 QSB along with a TFT touch panel.

When going thro the imxfb.h under arch/arm/plat-mxc/include/mach/imxfb.h

I notice this structure.

struct imx_fb_videomode {
    struct fb_videomode mode;
    u32 pcr;
    unsigned char    bpp;


What does this pcr and bpp symbolize? I'm totally new to framebuffers and any pointers on this would be appreciated.
