Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

It is "dts". Not "dtsi".

Sure, I will update to 'dtsi'.

Sorry please discard my previous reply.
I will update to dts.

Changes in V2:
    - Corrected syntax like alignmnet and kept nodes in sorted order.
    - Covered entire TCSR region.
    - Added 'firmware-name' property.

What "0" stands for?

0 means IRQ_NONE. These are software interrupts (register write),
so we have configured to 0. I will replace 0 with IRQ_NONE.

Thanks & Regards,
Manikanta.
