The PNP ACPI driver parses ACPI interrupt resource but not GpioInt resource. When the firmware passes GpioInt resource for IRQ the PNP ACPI driver ignores it and hence the interrupt for the particular driver will not work. One such example is 8042 keyboard which uses PNP driver for obtaining the interrupt resource. On Intel Braswell project GpioInt is used instead of interrupt resource and the keyboard driver fails to register interrupt. Fix the issue by parsing GpioInt resource type.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
