292 * AF9035 I2C sub header is 5 bytes long. Meaning of those bytes are:
293 * 0: data len

295 * 2: reg addr len
296 * byte 3 and 4 can be used as reg addr
297 * 3: reg addr MSB
298 * used when reg addr len is set to 2
299 * 4: reg addr LSB
300 * used when reg addr len is set to 1 or 2
301 *
302 * For the simplify we do not use register addr at all.
303 * NOTE: As a firmware knows tuner type there is very small possibility
304 * there could be some tuner I2C hacks done by firmware and this may
305 * lead problems if firmware expects those bytes are used.
306 *
307 * TODO: Here is few hacks. AF9035 chip integrates AF9033 demodulator.
308 * IT9135 chip integrates AF9033 demodulator and RF tuner. For dual
309 * tuner devices, there is also external AF9033 demodulator connected
310 * via external I2C bus. All AF9033 demod I2C traffic, both single and
311 * dual tuner configuration, is covered by firmware - actual USB IO
312 * looks just like a memory access.
313 * In case of IT913x chip, there is own tuner driver. It is implemented
314 * currently as a I2C driver, even tuner IP block is likely build
315 * directly into the demodulator memory space and there is no own I2C
316 * bus. I2C subsystem does not allow register multiple devices to same
317 * bus, having same slave address. Due to that we reuse demod address,
318 * shifted by one bit, on that case.
319 *
320 * For IT930x we use a different command and the sub header is
321 * different as well:
322 * 0: data len
323 * 1: I2C bus (0x03 seems to be only value used)
324 * 2: I2C addr << 1
