Because I copied it from the arm-gic.h header and forgot to rename
those macros :-).
I'll fix that.

Following up the discussion we had privately regarding these
macros (whether we really need them or not), maybe adding a comment
above the irqs property would be enough:

dumb_irq1_demux: dumb-irq-demux@1 {
compatible = "irqchip-dumb-demux";
interrupt-controller;
#interrupt-cells = <1>;
interrupts = <1 IRQ_TYPE_LEVEL_HIGH 7>;
/*
* Interrupt lines:
* 0: PMC
* 1: PIT
* 2: DBGU
* 3: RTT
* 4: WATCHDOG
* 5: RSTC
*/
irqs = <0x3f>;
};

Thanks,

Boris
