I did ask this question in multiple reviews, but never got an answer!
Are all the dp/hdmi port register range really volatile!?
Sorry for incomplete response in last review comment reply.
With making only specific DMA registers and interrupts registers true,
aplay was stuck.
Now we identified issue causing register and made it volatile.
With that change it seems working fine. After doing all the tests we
will share v9 series patch.
