in runtime I'd like to differentiate various IRQ chips by name. Here for
example I have one compatible "*-sic" and two actual IRQ chips SIC1 and
SIC2. If I read /proc/interrupts or /sys/kernel/debug/irq_domain_mapping
I would prefer to visualize interrupts from SIC1 and SIC2.

I understand that this property is not hardware specific, but there are
plenty of similar properties like "label" etc. Probably renaming of the
property may help?
