[Intel-gfx] [PATCH] drm/i915/icl: Add warn about unsupported CDCLK rates

2018-06-07 Thread Imre Deak
While checking workarounds related to the CDCLK PLL, I noticed that the DMC firmware bits for WA#1183 are missing for SKL. After that I clarified with HW people that it's not needed on SKL, since it doesn't support eDP1.4 which would be the only thing requiring the problematic CDCLK clock rates.
