What we have is: 1) Connector info read See get_ext_display_connection_info On some boards the connector information has to be read through a special I2C channel. This line is only used for this purpose and only on driver init. 2) SCDC stuff This should all be reworked to go through DRM's SCDC code. When this is done some unnecessary I2C code can be retired as well. 3) Max TMDS clock read See dal_ddc_service_i2c_query_dp_dual_mode_adaptor This should happen in DRM as well. I haven't checked if there's currently functionality in DRM. If not we can propose something. 4) HDMI retimer programming Some boards have an HDMI retimer that we need to program to pass PHY compliance. It would take a bit of time to address all of them. I'll add them on the TODO. 1 & 3 might be a good exercise if someone is looking for things to do.
