From: Paulo Zanoni <[email protected]> We want to split the HDMI connector and encoder initialization because in the future the DDI code will have its own "encoder init" function, but it will still call intel_hdmi_init_connector. The DDI encoder will actually have two connectors attached to it: HDMI and DP.
The best way to look at this patch is to imagine that we're renaming intel_hdmi_init to intel_hdmi_init_connector and removing the encoder-specific pieces and placing them into intel_hdmi_init.
