> Subject: [PATCH v4 0/2] Refactor MST DSC Determination Policy
>
> The patch series is to refactor existing dsc determination policy for dsc
> decompression and dsc passthrough given a mst output port.
>
> Original routine was written based on different peer device types which is not
> accurate and shows difficulty when expanding support of products that do not fully
> comply with DP specs.
>
> To make the routine more accurate and generic, the series includes below changes:
> 1. Refactor MST DSC determination policy solely based on
>    topology connection status and dsc dpcd capability info.
> 2. Dependency changes required for each vendor due to interface change.
>
> v2: split original single patch into two
> v3: rebase against the latest code
> v4: fix a ci issue
