Subject: Re: [PATCH v8 1/2] dt-bindings: net: can: Remove interrupt
 properties for MCAN

* Judith Mendez <jm@...com> [230530 22:48]:
> On AM62x SoC, MCANs on MCU domain do not have hardware interrupt
> routed to A53 Linux, instead they will use software interrupt by
> timer polling.
> 
> To enable timer polling method, interrupts should be
> optional so remove interrupts property from required section and
> add an example for MCAN node with timer polling enabled.
