This patch update interrupt property since we only use ASYS IRQ in the driver, and this may confuse people.

interrupts = <GIC_SPI 132 IRQ_TYPE_LEVEL_LOW>;What harm does having the extra information in the bindings do? If it's possible there might be a use for the extra interrupt it seems better to have people describe it.
Agreed. It should describe interrupts the h/w has, not what the driver (currently) uses.
Yes you're right. The current driver get IRQ number by index "0" but actually it should be "1" (GIC 132). Perhaps we can switch to use the platform_get_irq_byname() and add interrupt-name in DT so that binding can be agnostic of the IRQ order.
The binding is wrong already in that it says a single interrrupt. The example has 2 though. Add the 2nd interrupt and define the order such that you don't break the current driver. Probably that means ASYS is first.
