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
}
})
}
}
