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
