[Intel-gfx] [Patch 0/2] [DRM] :add the CVT/GTF algorithm in kernel space

[yakui_zhao]

Hi, All

	This is the patch set to add the CVT/GTF algorithm in kernel space. They are based on
the CVT/GTF function in xserver. But the CVT/GTF algorithm in xserver is realized by using float-point
calculation. And the float-point calculation had better be avoided in kernel space. I translate them
by using 32-bit integer calculation.
	Patch 1/2. Add the CVT algorithm . 
	The CVT function can be called to generate the required modeline based on the input parameters
        Patch 2/2. Add the GTF algorithm
	The GTF function can be called to generate the required modeline based on the input parameters.
    
	
Welcome the comments.

Best regards.
