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,
Mauro
