mainline inclusion
from mainline-v5.11-rc1
commit 356b01a9
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4HX08
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=356b01a986a5550ee16dd0b85306c6741f2d02d5



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

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
			}
		})
	}
}
