Subject: [PATCH] drm/i915: Show dmc debug registers on CFL and GLK
Date: Thu, 15 Mar 2018 15:35:02 +0200	[thread overview]
Message-ID: <20180315133502.4992-1-david.weinehall@linux.intel.com> (raw)

Since Coffee Lake uses the Kaby Lake DMC it's a safe
bet that the debug registers are the same. I haven't
double-checked that the GLK DMC uses the same registers
as BXT, but it seems as good of a guess as any.
