Hi Lisheng,

this patch got a bit mangled but I get where you're going.

I think Meson needs to be augmented to use hierarchical gpiolib irqchip
because this seems to be what the system is doing.

So start with drivers/pinctrl/meson/Kconfig and add:

select GPIOLIB_IRQCHIP
select IRQ_DOMAIN_HIEARARCHY

Then use the generic hierarchical gpiolib irqchip as described
in Documentation/driver-api/gpio/driver.rst
Type
git grep child_to_parent_hwirq
for several examples of how to do this.

Yours,
Linus Walleij
