We can keep asking about this but still testing does not happen :/ Best regards, Krzysztof

Thanks, we will add this test in the future to ensure that DTS, doc and driver are consistent. Best, Tao > > Best regards, > Krzysztof >

Correct the property name of the DSB MSR number that needs to be read in TPDM driver. The right property name is "qcom,dsb-msrs-num".
