class DSDIORegisterInterface: public DSDIOSession
/**
DSDIORegisterInterface Class
DSDIOSession derived, this class encapsulates the asynchronous nature of MMC
session requests, exposing a synchronous API to the client.
To ensure portability, it is recommended that the DSDIORegInterface be allocated
on behalf of the client by the appropriate function class after the client has
registered with the function (see TSDIOFunction::RegisterInterface for more details).
Unless stated otherwise, all register offsets are defined to be relative to offsets
within of the function (as opposed to absolute card addresses). This eliminates the
need for the device driver to require any knowledge of the internal memory map of the
SDIO card, other than that of the function being used.
