* AF9035 I2C sub header is 5 bytes long. Meaning of those bytes are:

|
* 0: data len
|
|
* 1: I2C addr << 1
|
|
* 2: reg addr len
|
|
* byte 3 and 4 can be used as reg addr
|
|
* 3: reg addr MSB
|
|
* used when reg addr len is set to 2
|
|
* 4: reg addr LSB
|
|
* used when reg addr len is set to 1 or 2
|
|
*
|
|
* For the simplify we do not use register addr at all.
|
|
* NOTE: As a firmware knows tuner type there is very small possibility
|
|
* there could be some tuner I2C hacks done by firmware and this may
|
|
* lead problems if firmware expects those bytes are used.
|
|
*
|
|
* TODO: Here is few hacks. AF9035 chip integrates AF9033 demodulator.
|
|
* 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.
|
|
*
|
|
* For IT930x we use a different command and the sub header is
|
|
* different as well:
|
|
* 0: data len
|
|
* 1: I2C bus (0x03 seems to be only value used)
|
|
* 2: I2C addr << 1
