v6: Update depends to Konrad's V15
    Rebase on top of V15
    Change 'acc_desc' check to accomodate v15 changes

v5:
This series tries to enable CPR on IPQ9574, that implements
CPRv4. Since [1] is older, faced few minor issues. Those are
addressed in [2].

    Update one commit message and add acked-by, reviewd-by

v4: s/cprh/cpr4/

    Update cloop-vadj & oloop-vadj with minItems

v3: Fix patch authorship for 2 patches
    Include CPR3 file changes done to Konrad's patches in https://github.com/quic-varada/cpr/commits/konrad/
    Change url for [2] to skip the cpr3 file changes

v2: Fix Signed-off-by order in 2 patches
    Update constraints in qcom,cpr3.yaml
    Add rbcpr_clk_src registration
    Add Reviewed-by to one of the patches
    Not adding Acked-by as the file has changed
