Recent dicussion on the mailing list [1], [2] outlined a need to document which intf type is used for DP and which one is used for eDP interfaces. This series implements my proposal [3]: - Keep INTF_EDP reserved for 8x74/8x84 - Use INTF_DP for all contemporary DP and eDP ports - Documet this in dpu_hw_mdss.h - Remove INTF_EDP usage in dpu1 driver. Main reasons behind this proposal: - It's not always possible to separate eDP and DP. For example INTF_5 on sc7280 is connected to combo eDP/DP PHY. - Using INTF_EDP would require us to split too many pieces, ending up with a singnificant amount of code duplication... - ... for nothing. From the DPU point of view there is no difference between DP and eDP interfaces as found on current SoC generations.
