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
