AM625: Is it possible to use MCU_MCAN0 or MCU_MCAN1 from A53 complex / linux?

Part Number: AM625

Hello,

We have a potential use-case that requires 2 CAN interfaces which would be controlled from linux (the A53 subssytem).

It looks like only MCAN0 can be controlled from linux, even though MCU_MCAN0/1 are visible in memory if their power domains are enabled.

Is it possible to use the MCU_MCAN0/1 devices from the A53/linux?  Or are the interrupts not able to be routed to the GIC / A53 subsystem?  Any thoughts on how to meet the requirements?  is there a reference design that would support the MCU to proxy the interface to the A53 cores?

Thanks.

Mike
