> That means the pin is just gpio input and not gpio input interrupt any
> more. So, move configuring ISEL in rzg2l_gpio_child_to_parent_hwirq()/
> rzg2l_gpio_irq_domain_free() so that pin will be gpioint always even
> during irq_disable().
>
> v1->v2:
> * Added as series by adding patch#2 and #3.
> * Replaced u32->u64 for pin_data
> * Added rzg2l_gpio_free() for error path for bitmap_find_free_region().
> * rzg2l_gpio_free() called during rzg2l_gpio_irq_domain_free().
