Commit Message

Taniya Das May 26, 2022, 4:26 a.m. UTC 
The clock gating control for TX/RX/WSA core bus clocks would be required
to be reset(moved from hardware control) from audio core driver. Thus
add the support for the reset clocks.

Also add the external mclk to interface external MI2S.

Fixes: 2b75e142523e ("clk: qcom: lpass: Add support for LPASS clock controller for SC7280").

This commit doesn't exist either:

git show 2b75e142523e
fatal: ambiguous argument '2b75e142523e': unknown revision or path not in the working tree.

You probably mean:

a9dd26639d05 clk: qcom: lpass: Add support for LPASS clock controller for SC7280

It seems you got these commit ids from a downstream branch, instead of an
upstream/maintainer branch.
