// To add new devices that will be accepted by the platform extension,
// follow to the example below.
//

//
// Step 1: Define a unique device type for each new device.
// (See acpispecific.h for details)
//

//
// Step 2: Define a name for each new device.
// (See acpispecific.h for details)

//
// The common library will consume the PepDeviceMatchArray to determine
// whether a device should be accepted by the platform extension.
// And then the common library will consult PepDeviceDefinitionArray for
// the native methods and device-specific notification handlers of the accepted
// devices.
//

//
// Step 3: Edit the PepDeviceMatchArray to tell the common library which device
// should be accepted by the platform extension. For each accepted device,
// specify which kind of notification (ACPI/DPM/PPM) the platform extension
// will handle and also specify the way platform extension should match its
// name (partial match or full match) when identifying the device.
// In this example, the sample platform extension only handles ACPI
// notifications for all devices and all devices should be matched by their
// full names.

//         while its _CID method will be handled asynchronously;

//         handled synchronously;

//         methods will be handled synchronously while _CRS method
//         will be handled asynchronously.
//     5) \_SB.BUSD.TST1 also synchronously handles
//         PEP_NOTIFY_ACPI_QUERY_DEVICE_CONTROL_RESOURCES.
//     6) \_SB.TST3 synchronously handles all
//         PEP_NOTIFY_ACPI_EVALUATE_CONTROL_METHOD except for _CID.
//         The processing for _CID is done in a self-managed manner (i.e. it is
//         processed asynchronously but does not rely on common library worker).
//         Hence there is no async worker registered.
//     7) \_SB.PWRR synchronously handles all
//         PEP_NOTIFY_ACPI_EVALUATE_CONTROL_METHOD.
