+ * IT9135 chip integrates AF9033 demodulator and RF tuner. For dual
+ * tuner devices, there is also external AF9033 demodulator connected
+ * via external I2C bus. All AF9033 demod I2C traffic, both single and
+ * dual tuner configuration, is covered by firmware - actual USB IO
+ * looks just like a memory access.
+ * In case of IT913x chip, there is own tuner driver. It is implemented
+ * currently as a I2C driver, even tuner IP block is likely build
+ * directly into the demodulator memory space and there is no own I2C
+ * bus. I2C subsystem does not allow register multiple devices to same
+ * bus, having same slave address. Due to that we reuse demod address,
+ * shifted by one bit, on that case.
