Does Linuxdrivers use the DMAMUX module in STM32MP1 ?

[Niklas Voi]

Hi,

we are currently evaluate the STM32MP for a project and we want to ensure that we can handle all errataissues that concern our usage scenario.

In Errata are the points: 2.6.1 to 2.6.4 that discribe DMAMUX issues. 

At this point my question is:

Does Linuxdrivers use the DMAMUX module in STM32MP1 ?

We dont find any codesnipets where the kernel is manipulating registers with this module.

Best regards,

Niklas
