By the way, how do you define two GPIOs/IRQs from different
gpio-banks/irq-controllers wuth that scheme?
Would that be like below?
ethernet@5,0 {
compatible = "smsc,lan9221", "smsc,lan9115";
interrupt-parent = <&gpio6>;
interrupts = <16 8>;
interrupt-parent = <&gpio7>;
interrupts = <1 IRQF_TRIGGER_FALLING>; /* GPIO7_1 */
};
So multiple definitions of interrupt-parent are allowed and the order
does matter? And such does work? Sorry for asking, but I'm relatively
new to DT. ;)
