What is cbass_main node?

I think you mean that since the existing example uses address cells and
size for 64bit addresses and sizes, you are introducing a bus segment
indicative of the same capability to reduce the churn in the binding.
Correct? if so, rephrase accordingly.

Your From: and Signed-off-by email IDs do not match. You might want to
re-read the contribution guidelines documentation in linux kernel.

This should be also tagged with Fixes: since it is fixing a pre-existing
binding that slipped through our review.

NOTE: at least my test.. (I think rob's system will still complain)
base: next-20210818
b4 am -o  ~/tmp -3 -g -t -l -c -s --no-cover

I mean, both these can be caught with checkpatch and standard checks, so
did you see that in your basic vett prior to posting?

Some 101 comments:

A) when you post a new revision, post a url like previous versions in
   diffstat - :
B) When you are sending the very first patch, it is already V1 and
   does'nt need to be explicitly stated. this update to your original
   post is a V2, so, when you update this patch to address the review
   comments, the next revision will be V3.

minor detail: you are also doing one additional change -> you are now using
the standard example template and adding the example node instead of a
complete example node as well here. Personally, I do prefer this
approach rather than the previous example.

Usually, when one sees problems like these, they tend to be
symptomatic, and we need to look if there is a similar pattern of
error else where in the codebase.

Sigh, in this case, I see the same problem in:
a) Documentation/devicetree/bindings/remoteproc/ti,k3-r5f-rproc.yaml
b) Documentation/devicetree/bindings/hwlock/ti,omap-hwspinlock.yaml

Hari, Sinthu,
Can we fix these in a series that belongs to each maintainer?
