drm/mode: add the GTF algorithm in kernel space
Add the GTF algorithm in kernel space. And this function can be called to generate the required modeline. I copied it from the file of xserver/hw/xfree86/modes/xf86gtf.c. What I have done is to translate it by using integer calculation. This is to avoid the float-point calculation in kernel space. At the same tie I also refer to the function of fb_get_mode in drivers/video/fbmon.c Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
