Krzysztof, I re-checked.
I am on the latest kernel (commit
5b913f5d7d7fe0f567dea8605f21da6eaa1735fb (tag: next-20241106,
origin/master, origin/HEAD)) and I am using the lastest dtschema v2024.9

❯ python3 -m pip list|grep 'dtschema'
dtschema                      2024.9

Still I am getting the below dtbs check errors while running `make
CHECK_DTBS=y ti/k3-am642-evm.dtb` without the binding change.

Let me know if I am missing something else.
