This patch adds the support for the gpio-signaled acpi event. This is used for power button on hisilicon D02 board, which is an arm64 platform. To support this function, _AEI and _Exx objects must be defined in the corresponding GPIO device as follows: Name (_AEI, ResourceTemplate () { GpioInt(Edge, ActiveLow, ExclusiveAndWake, PullUp, , " \\_SB.GPI0") {8} }) Method (_E08, 0x0, NotSerialized) { Notify (\_SB.PWRB, 0x80) } Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: qiujiang <qiujiang@huawei.com> --- drivers/gpio/gpio-dwapb.c | 6 ++++++ 1 file changed, 6 insertions(+)
