I need to check in details but 'interrupt-map' should be kept required.
Indeed, irq-mux needs this property to work. It is not an optional one.

I need to look at the 'make CHECK_DTBS=y' behavior when required property is
missing in a not enabled node (node with status = "disabled").

Also, got some:
Warning (interrupts_property): /soc/interrupt-controller@51000480: Missing interrupt-controller or interrupt-map property

This could be due to the presence of #interrupt-cells or the node name (not
sure). As I need to rename the node (Conor's comment), I will see if the
warning disappear. If the warning is due to #interrupt-cells, I don't think
that removing #interrupt-cells is the right solution to avoid the warning.

That's said, I need to perform some local tries. I will keep you informed.

Best regards
