Subject: ASoC: Intel: sof-rt5682: get bclk frequency from topology
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4524b1e3ef7884e0a54484dce8d921be7a06af13;p=linux.git

ASoC: Intel: sof-rt5682: get bclk frequency from topology

A different bclk frequency 3.072MHz was introduced to tgl platform and
is used in mtl topologies. Use SOF API to get frequency from topology
instead of hardcoding.
