IRQ_TYPE_NONE is not correct here -> it should have some polarity - if
it had none, there'd be no interrupt, right?
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>;
As this is for palmas interrupt controller, it does not use the second
field for interrupt from RTC.
So there is no really any polarity. It can be set to 0.
The second argument will be used for GPIOs mainly. However, support need
to be added on GPIO driver for rising/falling configuration.
