Looks like these are the magic bits that need to be set: dpll |= (7<<9) | (1<<13) | (1<<14); Anyone happen to have proper descriptions for these bits so I could add them to psb_intel_reg.h or thoughts on how/where an option could be exposed to enable these? On Mon, Apr 6, 2015 at 4:48 PM, George

gma500_gfx: spread spectrum clocking?

2015-04-06 Thread George McCollister
emgd had an option to enable spread spectrum clocking on LVDS. The documentation is vague but the setting that works is: Option "ALL/1/Port/4/Attr/43""7" Anyone have any idea how to set this with gma500_gfx or if it doesn't support it, how to put the hardware in this mode? Thanks, George
