You also need to change intel_port_is_tc(), several places only checks
for it and it would be broken for PORT_C in EHL.
bool intel_port_is_tc(struct drm_i915_private *dev_priv, enum port
port)
{
if (INTEL_GEN(dev_priv) >= 11 && !IS_ELKHARTLAKE(dev_priv))
return port >= PORT_C && port <= PORT_F;
return false;
}
