H A D | atombios_crtc.c | 5b40ddf8 Mon Feb 14 10:43:11 CST 2011 Alex Deucher <alexdeucher@gmail.com> drm/radeon/kms: hopefully fix pll issues for real (v3)
The problematic boards have a recommended reference divider to be used when spread spectrum is enabled on the laptop panel. Enable the use of the recommended reference divider along with the new pll algo.
v2: testing options
v3: When using the fixed reference divider with LVDS, prefer min m to max p and use fractional feedback dividers.
