According to the Microsoft documentation for Windows 8 convertible devices, these devices should implement a PNP0C60 "laptop/slate mode state indicator" ACPI device. This device can work in 2 ways, if there is a GPIO which directly indicates the device is in tablet-mode or not then the direct-gpio mode should be used. If there is no such GPIO, but instead the events are coming from e.g. the embedded-controller, then there should still be a PNP0C60 ACPI device and event-injection should be used to send the events. The drivers/platform/x86/intel-vbtn.c code is an example from a standardized manner of doing the latter. On various 2-in-1s with either a detachable keyboard, or with 360° hinges, the direct GPIO mode is indicated by an ACPI device with a HID of INT33D3, which contains a single GpioInt in its ACPI resource table, which directly indicates if the device is in tablet-mode or not. This commit adds support for this to the soc_button_array code, as well as for the alternative ID9001 HID which some devices use instead of the INT33D3 HID.
