I think there's at least a few more spots that need && !IS_VALLEYVIEW():

---
	} else if (!HAS_PCH_CPT(dev) || is_cpu_edp(intel_dp)) {
		if (!HAS_PCH_SPLIT(dev))
			intel_dp->DP |= intel_dp->color_range;
---
		if (is_cpu_edp(intel_dp)) {
			/* don't miss out required setting for eDP */
			if (adjusted_mode->clock < 200000)
				intel_dp->DP |= DP_PLL_FREQ_160MHZ;
			else
				intel_dp->DP |= DP_PLL_FREQ_270MHZ;
		}
---

BR,
Jani.
