297	 *    byte 3 and 4 can be used as reg addr
298	 * 3: reg addr MSB
299	 *    used when reg addr len is set to 2
300	 * 4: reg addr LSB
301	 *    used when reg addr len is set to 1 or 2
302	 *
303	 * For the simplify we do not use register addr at all.
304	 * NOTE: As a firmware knows tuner type there is very small possibility
305	 * there could be some tuner I2C hacks done by firmware and this may
306	 * lead problems if firmware expects those bytes are used.
307	 *
308	 * TODO: Here is few hacks. AF9035 chip integrates AF9033 demodulator.
309	 * IT9135 chip integrates AF9033 demodulator and RF tuner. For dual
310	 * tuner devices, there is also external AF9033 demodulator connected
311	 * via external I2C bus. All AF9033 demod I2C traffic, both single and
312	 * dual tuner configuration, is covered by firmware - actual USB IO
313	 * looks just like a memory access.
314	 * In case of IT913x chip, there is own tuner driver. It is implemented
315	 * currently as a I2C driver, even tuner IP block is likely build
316	 * directly into the demodulator memory space and there is no own I2C
317	 * bus. I2C subsystem does not allow register multiple devices to same
318	 * bus, having same slave address. Due to that we reuse demod address,
319	 * shifted by one bit, on that case.
320	 *
321	 * For IT930x we use a different command and the sub header is
322	 * different as well:
323	 * 0: data len
324	 * 1: I2C bus (0x03 seems to be only value used)
325	 * 2: I2C addr << 1
