After another look at the driver, both seems to be fixed
address. There are even some comments that implies that:

	/* SOC_PMIC_IRQ_MASK_0_ADDR */
	ret = of_property_read_u32(np, "irq-mask-addr", &pmic->irq_mask_addr);

	/* SOC_PMIC_IRQ0_ADDR */
	ret = of_property_read_u32(np, "irq-addr", &pmic->irq_addr);

So, I'll just drop the entire set of irq-* properties. The PMIC part
should be just this:

	#include <dt-bindings/spmi/spmi.h>
...
		pmic: pmic@0 {
			compatible = "hisilicon,hi6421v600-spmi";
			reg = <0 SPMI_USID>;

			#interrupt-cells = <2>;
			interrupt-controller;
			gpios = <&gpio28 0 0>;
...
		};



Thanks,
