[Intel-gfx] [PATCH 6/6] drm/i915: Try to fix CRT port clock limits

2016-02-17 Thread ville . syrjala
From: Ville Syrjälä LPT/WPT-H are limited to max 180 MHz CRT dotclock. Most other platforms have a limit of 350 MHz. Supposedly gen3 and gen4 go up to 400 MHz. VLV is a bit special since the docs are poor. Supposedly the DAC would be good up to 355 MHz, but currently we limit the DPLL to 270 MHz
