Windows 10 tablets with gpio buttons will typically use the ACPI 6.0 Generic Button Device with a HID of ACPI0011 for these buttons. The ACPI description for these in the ACPI0011 devices _DSD object uses something resembling HID descriptors, except that instead of indicating a bit index into a HID input report, the index indicates the _CRS index for the GPIO. The use of 1 interrupt per button, some of which need to be wakeup sources, instead of using input reports makes it impossible to use the HID subsystem for this. This really is just another gpio-keys input device with the platform data described in ACPI, so this commit adds parsing for this new way to describe gpio-keys to the soc_button_array driver.

README
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.
