No underscores in node names.

Missing "state" suffix. See:
https://lore.kernel.org/linux-arm-msm/20221018155721.47140-1-krzysztof.kozlowski@linaro.org/

Bindings are already in next.

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