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
