hmm, in the code is IRQ_TRIGGER_FALLING but here is LEVEL_LOW, hmm what
it is really?
+ reset-gpios = <&pio 7 1 GPIO_ACTIVE_HIGH>;
hmm, if the reset gpio at the chip is active low (I guess it is) that
would indicate an inverter between SoC and gpio. So a nonstandard setup
as an example, probably not a good idea.

Andreas
