Wysocki" , Linus Walleij , Alexandre Courbot Cc: Hans de Goede , linux-acpi@vger.kernel.org, Andy Shevchenko , linux-gpio@vger.kernel.org Hi All, Here is v4 of my patch adding a driver for the ACPI INT0002 Virtual GPIO device. When I started working on this driver using 4.11 as kernel this fixed an irq-storm on irq 9, with some of the recent suspend-to-idle wakeup changes which have landed in 4.12-rc1 this "driver" is necessary to fix affected systems getting stuck in suspend when the user tries to wake them through a peripheral which signals PME to the PMC to wakeup the system, such as the xHCI controller. As such ideally this driver should get added to a later 4.12-rc# as a bugfix. Also see this linux-acpi mailinglist-thread: https://www.spinics.net/lists/linux-acpi/msg74614.html Regards, Hans
