This means this is stm32mp15 SoC. I do not see such SoC on list of your
SoCs in bindings. What's more, there are no bindings for other SoC
components for stm32mp15!

Something is here not matching - this change, this DTSI, top level
bindings or all of your SoC device/blocks bindings.



Best regards,
Krzysztof
