Add i8042 state to the platform data to help i8042 driver make decision whether to probe for i8042 or not. We recognize 3 states: platform/subarch ca not possible have i8042 (as is the case with Inrel MID platform), firmware (such as ACPI) reports that i8042 is absent from the device, or i8042 may be present and the driver should probe for it. The intent is to allow i8042 driver abort initialization on x86 if PNP data (absence of both keyboard and mouse PNP devices) agrees with firmware data. It will also allow us to remove i8042_detect later.

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.
