These INT33D3 devices follow yet another Intel defined (but not documented) ACPI GPIO button standard. Unlike the ACPI GPIO button devices supported so far, the GPIO used in the INT33D3 devices is active-high, rather then active-low. This commit makes setting the gpio_keys_button.active_low flag configurable through the soc_button_info struct and enables it for all currently supported devices.

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.
