After these days of trying, I guess there are still some bugs on gpio - regmap - irq.
It looks like an compatibility issue with gpio_irq_chip and regmap_irq_chip (My rough
fixes seems to work).
Other than that, it seems to be no way to add interrupt trigger in regmap_irq_thread(),
to solve the both-edge problem for my hardware.
I'd be willing to use gpio-regmap if above issues worked out, I learned IRQ controller,
IRQ domain, etc. , after all. But if not, I'd like to implement GPIO in the original way,
it was tested to work. May I? Thanks for all your suggestions.
