Hello, device tree folks,
Can I ask a little piece of advice?
Which is a preferred way for specifying an interrupt property,
interrupt-parent & interrupts, or interrupts-extended ?
There is only one interrupt controller on my SoC,
so I think either should work enough for me.

The main purpose of interrupts-extended is to allow one device to have multiple interrupts that are handled by different controllers, without introducing a (more complex) interrupt-map property in the parent.

OK, I will use interrupt-parent & interrupts.
