If there is a need to exclude certain GPIOs from the IRQ domain, one can
set .irq_need_valid_mask of the gpiochip before gpiochip_add_data() is
called. This allocates .irq_valid_mask with as many bits set as there are
GPIOs in the chip. Drivers can exclude GPIOs by clearing bits from this
mask. The mask must be filled in before gpiochip_irqchip_add() is called.
* gpiochip_set_chained_irqchip(): sets up a chained irq handler for a
gpio_chip from a parent IRQ and passes the struct gpio_chip* as handler
data. (Notice handler data, since the irqchip data is likely used by the
