[PATCH 0/9] prunue audio frequencies based on bw limits for DP2

[Vinod Govindapillai]

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.

TODO: Update the hblank available calculations for Xe3

Vinod Govindapillai (9):
  drm/i915/display: get rid of encoder param  in
    intel_audio_compute_config
  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: update logic to determine crtcstate has audio
    support
  drm/i915/display: check and prune audio frequencies based on bw limits
  drm/i915/display: iterare through channels if no feasible frequencies
  drm/i915/display: update audio support based on the available
    frequencies
  drm/i815/disaply: limit the audio bw check with DP2 config
  drm/i915/display: update audio bw calculations for MTL
