One typo and one remark below

Add stm32mp15x prefix to all STM32MP15x board specific function,
this patch is a preliminary step for STM32MP13x support.
This patch also add the RCC probe to avoid circular access with

OK
usbphyc probe as clk provider.

I am wondering if usage of DM_FLAG_PROBE_AFTER_BIND in flag would avoid this
above piece of code ?
Yes, I think you are right
=> need to be tested when RCC clock driver and USBPHY clock will be
upstreamed
and then we will remove these lines
