dbd1c54fc8 gpio: Bulk conversion to generic_handle_domain_irq() 
Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

356b01a986 gpio: gpio-hisi: Add HiSilicon GPIO support 
This GPIO driver is for HiSilicon's ARM SoC.

HiSilicon's GPIO controller support double-edge interrupt and multi-core
concurrent access.

ACPI table example for this GPIO controller:
Device (GPO0)
{
	Name (_HID, "HISI0184")
	Device (PRTA)
	{
		Name (_ADR, Zero)
		Name (_UID, Zero)
		Name (_DSD, Package (0x01)
		{
			Package (0x02)
			{
				"ngpios",
				0x20
			}
		})
	}
}
