My review was only about patch correctness, not overall patch preference.

I appreciate your work Kuldeep, it is important and valuable
contribution. It is sad to see duplicated effort, I don't like it for my
own patches either. In general, I believe the FIFO approach should be
applied, so in this case Bhupesh patches.

Before starting the conversion the best is to look for prior work on lore:
https://lore.kernel.org/lkml/?q=dfn%3Aqcom_bam_dma.txt
This way you could easily avoid doing the same.

Bhupesh,
Please check what was stopping your work, you might need to rebase it
and resend it.

Best regards,
Krzysztof
