[PATCH] drm/i915: Allow PCH DPLL sharing regardless of DPLL_SDVO_HIGH_SPEED
(linux 4.4.16)

It worked. Just modified your patch to be able to apply in my kernel (v4.4.14
LTS), using "intel_pipe_has_type" instead of "intel_crtc_has_type". Is that
correct?

+       if (INTEL_INFO(dev_priv)->num_pipes == 3 &&
+           intel_pipe_has_type(intel_crtc, INTEL_OUTPUT_ANALOG))
+               dpll |= DPLL_SDVO_HIGH_SPEED;
+
