+ * passive.  But with the split between (for example) DTV within MDP4,
+ * and HDMI encoder, we really need two parts to an encoder.  Instead
+ * what we do is have the part external to the display controller block
+ * in the connector, which is called from the encoder to delegate the
+ * appropriate parts of modeset.
