The chip contains 4 demod modules that run in parallel and are independently controllable via separate I2C addresses. Two of the modules are for ISDB-T and the rest for ISDB-S. It is used in earthsoft pt3 cards. Note that this driver does not init the chip, because the initilization sequence / register setting is not disclosed. Thus, the driver assumes that the chips are initilized externally by its parent board driver before fe->ops->init() are called. Earthsoft PT3 PCIe card, for example, contains the init sequence in its private memory and provides a command to trigger the sequence.
