Hi Krzysztof,
I should have mentioned it in the commit message:
Currently, same feature list as on STM32MP1x is supported.
New capture input stage is now available in the hardware. It's not added
yet to the driver.
The Low Power Timer (LPTIM) hardware isn't fully backward compatible,
hence add a new compatible to properly support it.
Best regards,
Fabrice
