|/ | | | | | | | | | | | | | | | | | | | | | | | | | | [why] 1. Current code hard codes link to PHY mapping in dc link level per asic per revision. This is not scalable. In long term the mapping will be obatined from DMUB and store in dc resource. 2. Depending on DCN revision and endpoint type, the definition of dio_output_idx dio_output_type and phy_idx are not consistent. We need to unify the meaning of these hardware indices across different system configuration. [how] 1. Temporarly move the hardcoded mapping to dc_resource level, which should have full awareness of asic specific configuration and add a TODO comment to move the mapping to DMUB. 2. populate dio_output_idx/phy_idx for all configuration, define usb4_enabled bit instead of dio_output_type as an external enum.
