NXP LPC32xx has three interrupt controllers, namely root Main
Interrupt Controller (MIC) and two supplementary Sub Interrupt
Controllers (SIC1 and SIC2), four interrupt outputs from SIC1 and SIC2
are connected to MIC.

Also the change describes two additional optional properties:
* interrupt-controller-name - human readable name of an interrupt
  controller,

Why? compatible is human readable. If you don't like that, then put the 
string in the driver.

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?

You can always generate the name based on the probing order or the address.

Thanks,
