This change was not there in the original patch that I shared, you
should add this change in a separate patch, as first patch converts to
yaml and next one adds new bindings.
This is also not following yaml style bindings.
Please take some time to look at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/example-schema.yaml?h=v5.16-rc2
to add new binding.
