intel/skylake: nhlt: Update Max98373's capture format
Max98373's NHLT capture configuration is used for IV feedback for DSM algorithm. Feedback is 4-channel data. Without this configuration below error is seen in dmesg: [ 315.784250] snd_soc_skl 0000:00:1f.3: Blob NULL for id 0 type 3 dirn 1 [ 315.784263] snd_soc_skl 0000:00:1f.3: PCM: ch 4, freq 48000, fmt 32 So, update nhlt configuration accordingly. BUG=b:79362472 TEST=Audio playback works with IV feedback enabled Change-Id: I75434a63fe030ed9bb963c6d300d833a8e7d2d66 Signed-off-by: Sathyanarayana Nujella <sathyanarayana.nujella@intel.com> Reviewed-on: https://review.coreboot.org/26384 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
