    Subject[RESEND v3 4/4] clk: qcom: lpasscc-sc7280: Add resets for audioreach
    Date
    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 in audioreach based clock driver.
