is incorrect.

7db7ade270 drm/amd/display: Skip writeback connector when we get amdgpu_dm_connector 
[WHY]
Writeback connectors are based on a different object:
drm_writeback_connector, and are therefore different from
amdgpu_dm_connector. We need to be careful to ensure code
designed for amdgpu_dm_connector doesn't inadvertently try
to operate on a drm_writeback_connector.

[HOW]
Skip them when connector type is DRM_MODE_CONNECTOR_WRITEBACK.

80af8859b4 drm/amd/display: Skip entire amdgpu_dm build if !CONFIG_DRM_AMD_DC 
[WHY]
Previously this only excluded build for a few amdgpu_dm
binaries which makes no sense.

[HOW]
Wrap the entire Makefile in "ifneq ($(CONFIG_DRM_AMD_DC),)"

b6411638c0 drm/amd/display: Avoid virtual stream encoder if not explicitly requested 
Virtual stream encoder should not be a free match for thunderbolt or
usbc, and thus should be avoided.

08a32addf1 drm/amd/display: add support for DTO genarated dscclk 
Current implementation will choose to use refclk as dscclk. This is not
recommended by hardware team as refclk is a fixed value which could
cause unnecessary power consumption or it could be not enough for large
DSC timings. So we are adding new interfaces so we could switch to use
dynamically generated DSCCLK by DTO. So DSCCLK is programmable based on
current pixel clock and dispclk.
