Well, it just translates IRQ_TYPE_NONE through

Linux/include/dt-bindings/interrupt-controller/irq.h

to 

interrupts = <8 0>;

which is given as an example in

Documentation//devicetree/bindings/rtc/rtc-palmas.txt

Since I don't know anything about the rtc driver beyond the bindings documentation I assume it is correct...
I have added Laxman Dewangan because he introduced this interrupts = <8 0>;
