clcdfb: Question about clcdfb_check() routine

Hi Russell,

I had a doubt on clcdfb_check() routine in include/linux/amba/clcd.h.
Hard coded lower value of right margin, left margin and hsync len is (5+1).

Is there any specific reason behind it??
Can we make it 1 for more generic uses of the same??

If i am not wrong these values can vary from 0 to 255.

Thanks and Regards
Vipul Samar
