drm/amd/display: handle active dongle port type is DP++ or DP case

2019-07-18T19:17:20Z

[Why]: Some active dongles have DP++ port and DP port at the same time. Current code doesn't cover DP++ case and processes as default DVI case, in which audio is disabled. Because of dual mode, DP case is also treat as DVI case for the other port. [How]: According DP 1.4 spec, add DP++ procedure similar with HDMI case. Also add None dongle type for DP case.

drm/amd/display: update DSC MST DP virtual DPCD peer device enumeration policy

2019-06-22T14:34:13Z

[why] Current policy assumes virtual DPCD peer device as an individual MST branch device with 1 input and 1 output. However this is only true for virtual DP-to-DP peer device. In general there are three types of virtual DP peer devices. 1. Sink peer device with virtual DPCD. 2. Virtual DP-to-DP Peer device with virtual DPCD. 3. Virtual DP-to-HDMI Protocol Converter Peer Device with Virtual DPCD. So we should break the assumption and handle all three types. [how] DP-to-DP peer device will have virtual DPCD cap upstream. Sink peer device will have virtual DPCD on the logical port. Dp to HDMI protocol converter peer device will have virtual DPCD on its converter port. For DSC capable Synaptics non VGA port we workaround by enumerating a virutal DPCD peer device on its upstream even if it doesn't have one.

drm/amd/display: make clk mgr soc specific

2019-05-31T15:39:29Z

[Why] First step of refactoring clk mgr to better handle different ways of handling clock operations. Clock operation policies are soc specific and not just DCN vesion specific. It is not a hw resource, should not be in the resource pool. [How] Change clock manager creation to be based on HW internal ID, rename clock manager members to be more clear. Move clock manager out of resource. Signed-off-by: Eric Yang Reviewed-by: Tony Cheng Acked-by: Leo Li Signed-off-by: Alex Deucher
