* platform/x86: dell-ddv: Add documentationArmin Wolf2023-05-091-0/+296
| | | | | | | | | | | | | | The WMI interface used by the dell-wmi-ddv driver contains many methods which are currently unused, making it difficult to document these inside the drivers source code. Create the necessary documentation based on current knowledge so that all details of the WMI interface can be written down for later use.

* platform/x86: wmi: Add device specific documentationArmin Wolf2023-05-093-0/+48
| | | | | | | | | | | | Add a place for device-specific documentation of WMI drivers. The first entry is documentation for the wmi-bmof driver, with additional documentation being expected to follow.

Add documentation for the WMI subsystem. The documentation describes both the ACPI WMI interface and the driver API for interacting with the WMI driver core. The information regarding the ACPI interface was retrieved from the Ubuntu kernel references and the Windows driver samples available on GitHub. The documentation is supposed to help driver developers writing WMI drivers, as many modern machines designed to run Windows provide an ACPI WMI interface.
