This driver is used to simulate a keyboard. For example, user could read GPIO setting or data from RAM address. If the value matches the expected pattern, it could trigger a key pressed event. User needs to implement hooks of PLATFORM_VIRTUAL_KBD_PROTOCOL. There're 4 hooks in this protocol. Register(): Quote the interface that user needs. For example, user needs to locate GPIO protocol if he wants to simulate a GPIO value as a key. Reset(): Do the initialization before reading value. Query(): Read value. If the value matches the expected pattern, trigger a key pressed event. Clear(): Clean the value if necessary.
