> Subject: [PATCH v2 0/6] prunue audio frequencies based on bw limits for DP2
> 
> Implement pruning of unsupported audio frequencies from SAD frequency list
> based on the audio bw calculation specified in Bspec: 67768. First for the
> maximum number of channels, supported audio frequency list is checked. If
> there are no available frequencies exist for channel, channel is reduced and the
> assessment is done again. Eventually both supported audio frequency and
> channels are updated to SAD in ELD.
> 
> v2: updated the series based on review comments. One patch from the
>     previous revision is dropped and two other patches squashed to
>     another patch
> 
> Audio bw limits calculations for xe3 need to be addressed separately
> 
> Vinod Govindapillai (6):
>   drm/i915/display: create a common function to check validity of ELD
>   drm/i915/display: update call to intel_dp_audio_compute_config
>   drm/i915/display: check and prune audio frequencies based on bw limits
>     in DP2.0
>   drm/i915/display: iterate through channels if no feasible frequencies
>   drm/i915/display: update audio support based on the available
>     frequencies
>   drm/i915/display: update audio bw calculations for MTL
