Hi Alex, I have just a single head display.  How can I override the values
specified by the oem (powercolor in my case).  Their values for low don't work
for me.  I suspect I need something between their low and mid.  or can a power
quirk be added for this card?

Also wondering what the values are.  I turned on drm.debug=1 but couldn't see
any clock/mem debug output, just voltage:

[  426.411143] [drm:evergreen_pm_misc], Setting: v: 950

Tried dynpm method but didn't see anything interesting either.  Also noticed
that dynpm draws slightly more power than mid at idle.
