296 * 2: reg addr len
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
