adjust up the clock slightly on rs6xx TDMS
Does this patch help?
This patch seems to help when combined with "RADEON_PLL_USE_FRAC_FB_DIV | RADEON_PLL_PREFER_CLOSEST_HIGHER |RADEON_PLL_NO_ODD_POST_DIV".
For now after a single session of 2h, it even seems more stable than ums (where occasional losses of images happen maybe every 20-30mins on average).
I've tried other combinations as well with various success:
- RADEON_PLL_PREFER_CLOSEST_LOWER => unstable-ish - RADEON_PLL_USE_FRAC_FB_DIV => black - RADEON_PLL_PREFER_CLOSEST_LOWER | RADEON_PLL_USE_FRAC_FB_DIV => not very stable - RADEON_PLL_PREFER_CLOSEST_HIGHER => not stable - RADEON_PLL_USE_FRAC_FB_DIV | RADEON_PLL_PREFER_CLOSEST_HIGHER => not stable
I can provide the registers for the different tests if that could be of any uses.
