Recent Kontron COMe modules identify the PLD device using the hardware id KEM0001 in the ACPI table. This patch adds support for probing the device using the HID and also retrieving the resources. As this is not available for all products, the DMI based detection still needs to be around for older systems. It is executed if no matching ACPI HID is found during registering the platform driver or no specific device id is forced. If a device is detected using ACPI and no resource information is available, the default io resource is used. Forcing a device id with the force_device_id parameter and therefore manually generating a platform device takes precedence over ACPI during probing.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
