Browse source 
In order to consolidate the multiple ways to associate an IRQ chip with
a GPIO chip, move more fields into the new struct gpio_irq_chip.

mark all the child IRQs as having the other IRQ as parent.
If there is a need to exclude certain GPIOs from the IRQ domain, you can
set .irq_need_valid_mask of the gpiochip before gpiochip_add_data() is
called. This allocates an .irq_valid_mask with as many bits set as there
set .irq.need_valid_mask of the gpiochip before gpiochip_add_data() is
called. This allocates an .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() or
gpiochip_irqchip_add_nested() is called.
