Hi Ulf,

I just copied (and added "for STM32MP25") what was done for STM32MP1x:
       - description: Entry for STMicroelectronics variant of PL18x.
           This dedicated compatible is used by bootloaders.
         items:
           - const: st,stm32-sdmmc2
           - const: arm,pl18x
           - const: arm,primecell
       - description: Entry for STMicroelectronics variant of PL18x for
           STM32MP25. This dedicated compatible is used by bootloaders.
         items:
           - const: st,stm32mp25-sdmmc2
           - const: arm,pl18x
           - const: arm,primecell


Should I remove (or adapt) both descriptions?


Best regards,
Yann
