On QCM6490-IDP and QCS690-RB3Gen2 boards, the HLOS Audio driver requires the support for the reset functionality only from the LPASS region. Rest of the clocks functionality is controlled from LPASS firmware. Hence, in the earlier series we marked all the clocks as protected and introduced new "qcom,adsp-skip-pll" flag to skip PLL configurations. But as the flag was also not approved and the ask was to use the compatible string, we went ahead with this approach. > > Best regards, > Krzysztof >

Is this also applicable for the QCM6490 FairPhone5? If so, maybe it's time to have qcm6490.dtsi.

Certain clocks are not accessible on QCM6490-IDP board, thus mark them as protected. Update the lpassaudio node to support the new compatible.
