Re: [PATCH v9 2/4] dt-bindings: stm32: update DT bingding for stm32mp25

Hi Conor,

Thank's for your review.

Yes, I have checked that point. I have also written the RCC driver for 
TFA/OPTE/UBOOT and once

I receive Ack in the Kernel, I will upstream the other components.

Best Regards

Gabriel

Now RCC driver use '.index' of clk_parent_data struct to define a parent.
The RCC driver in linux might have stopped using the names, but they
were a required property that could be replied upon by other software
too. Have you checked U-Boot or *BSD etc to make sure clock-names are
not used there?

Thanks,
Conor.

The majority of parents are SCMI clocks, then dt-bindings must be fixed.
