Like for stm32mp15, when stm32 RCC node is used to interact with a secure
context (using clock SCMI protocol), a different path has to be used for
yaml verification.

Hi Rob, Krzysztof,
If you agree with this patch, I'll apply it directly in my STM32 tree.
Thanks
Alex

You don't need '-secure' because it's always secure?

Yes "st,stm32mp1-rcc" is for the STM32MP15.

Yes. Compare to STM32MP15, the STM32MP13 is by default "secure". In our
case it is "mapped" to OPTEE, using SCMI protocols.
