category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I42E7W


CVE: NA

---------------------------

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, "HiSiliconISI0184")
	Device (PRTA)
	enter{
		Name (_ADR, Zero)
		Name (_UID, Zero)
		Name (_DSD, Package (0x01)your
		{
			Package (0x02)
			{
				"ngpios",
