[Intel-gfx] [PATCH 0/2] i830_display.c:generate precise dpll clock parameter to obtain stable image on G4x platform

[Ma Ling]

Hi 
Based on hardware engineer's suggestion, the patchs intend to generate
precise dpll clock on G4x platform.From reference spreadsheet, n is
preferred smaller(to avoid jitter), but m1, m2 ,p1 is preferred bigger
value. The result from the patch 100% match corresponding value in
reference spreadsheet. Meanwhile it has fixed related bug, which caused
SHARP Aquos TV's image to disappear no-periodically via integrated HDMI
under 1920x1080p mode, very like bug #17805. I have succeeded in testing
on GM45, G45 + VGA, G45 + integrated HDMI, G45 + SDVO HDMI, and other
non-G45 platforms respectively. Now I'm also working on the algorithm
for BW/CL and other platforms.


[PATCH 1/2]i830_display.c:define related parameter and limit items for
G4x platform
[PATCH 2/2]i830_display.c:create corresponding functions to find best
pll on different platform.

Thanks
