 295          * via external I2C bus. All AF9033 demod I2C traffic, both single and
 296          * dual tuner configuration, is covered by firmware - actual USB IO
 297          * looks just like a memory access.
 298          * In case of IT913x chip, there is own tuner driver. It is implemented
 299          * currently as a I2C driver, even tuner IP block is likely build
 300          * directly into the demodulator memory space and there is no own I2C
 301          * bus. I2C subsystem does not allow register multiple devices to same
 302          * bus, having same slave address. Due to that we reuse demod address,
 303          * shifted by one bit, on that case.
 304          *
 305          * For IT930x we use a different command and the sub header is
