Oh I know that issue and it should be fixed by:
https://marc.info/?l=linux-kernel&m=154745840513141&w=3
The root cause is that max77620 doesn't have a dedicated gpio interrupt mask
register,
so the "mask_base" of max77620 gpio driver is 0, that's why regmap_add_irq_chip
writes 0xFF
to offset zero
Oh yeah will do, thanks.
