Hi,
I have looked into regmap-irq, it appears that using the default irq
thread_fn(regmap_irq_thread) is required. However, due to hardware
limitation,
we need to inspect the IRQ_TYPE to determine whether to manage the irq
within
the irq handler. I think our irq portion does not perfectly fit the
regmap-irq.
Moreover, it seems that the gpio-regmap.c file needs to be modified if
the GPIO driver
requires debounce settings. I think the gpio-regmap may not be
appropriate for our driver.
Do you have any suggestions?
Can't say anything regarding the interrupt handling but adding literally
one line to gpio-regmap shouldn't be a reason not to use it.
