Hi Krzysztof 

I hope this email finds you well. I have a couple of questions
regarding the EXDMA commit patch and decoupling:

1. Would removing the example from the EXDMA commit patch be sufficient
to achieve decoupling for EXDMA YAML and MTK clock/power header?

2. If removing the example from the EXDMA YAML is not allowed, what
alternative changes could we implement to achieve decoupling?

Thank you for your time and expertise. I appreciate any insights you
can provide.

Best regards,

Paul
