Hi Andy,

I did hit few issues while trying out SLIMBus BAM on DB820c, this BAM instance
is remotely controlled and powered up after ADSP is booted using QMI commands.

What do you mean by "remotely controlled" in this series?

Firstly some of the master registers are written even when the BAM is remotely
controlled, and secondly reading registers when bam is not ready yet.

These 4 patches address these issues, there are few more issues like doing PM
in simillar usecase, these will be addressed soon.

Thanks,
Srini
