Thank you for your patch. There is something to discuss/improve.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

status is the last.

Are these valid properties for this node? Did you check with bindings?

Keep status last, please.

I'm sorry I was not aware of checking the DTS against bindings. I'll do 
the due diligence going forward. `make dtbs_check is throwing error of 
"No rule to make target". Not sure if we need pass any options to the 
command. I did try to understand the problem but all went in vain. Pls 
help understand if I'm missing anything.

There is doc explaining possible usage, but in general works perfect
without argument. If you do not have such target, means you run it on
some ancient kernel, so anyway patch cannot be accepted and has to be
rebased. Please always develop on newest kernel - newest mainline rc,
maintainer's for-next branch or linux-next.

I'm working on the latest kernel (ath.git which is maintained by Kalle 
Valo for Atheros drivers). I'll give a try on the linux-next branch once.

Hi Krzysztof,

I have tested the DTS against the bindings. Have used this command `make 
CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 dtbs_check -m 
DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/wireless/qcom,ath11k.yaml`.

`make dtbs_check` did not report any error.

Thanks,
Manikanta

You selected some schema to test, so yes, maybe it passes. It's not a
proof of anything. Run with either applicable bindings (the one which I
commented about) or with all of them.

If you did it, you would see the check will fail. The bindings would
report error. There is no need to engage reviewers if bindings find the
errors for you, right?

Nodes you added here are not allowed.

Best regards,
Krzysztof

Thanks for the inputs Krzysztof, I now see the following error
"smp2p-wpss: 'wlan-ap-to-wpss', 'wlan-wpss-to-ap' do not match any of 
the regexes: '^master-kernel|slave-kernel|ipa-ap-to-modem|ipa-modem-to-ap$'"

After making changes to the smp2p binding, I did not see this error.
Following are the changes made.

  patternProperties:
-  "^master-kernel|slave-kernel|ipa-ap-to-modem|ipa-modem-to-ap$":
+ 
"^master-kernel|slave-kernel|ipa-ap-to-modem|ipa-modem-to-ap|wlan-ap-to-wpss|wlan-wpss-to-ap$":

Shall I go ahead and make the smp2p binding change?

Thanks,
Manikanta

If it is correct change, then yes.
