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