Hi Vincent,
I'm not sure that all driver's functionality is supported by ZL3064x. Did you test everything?

I need to check datasheets for this chip models, maybe some device flags will be needed.

I checked both datasheets. They are the same registers:

   - the register descriptions are verbatim identical

   - same chip-ID encoding (base / A +0x1000 / B +0x2000 / 7x7 +0x8000)

So ZL_CHIP_INFO(0x0E3B, 3, ZL3073X_FLAG_REF_PHASE_COMP_32) is correct
and no new device flag is needed: the ref-phase mechanism the flag
governs is identical between the families.

The only differences seem to be non-register related: line card vs
central system and the min input-frequency spec (1 kHz vs 0.5 Hz).

Hi Vincent,

Yes, minimal reference frequency for zl3064x is 1000Hz and also
supported bandwidth range is different (not relevant now).

So, we need to
- add new field into zl3073x_chip_info that will describe minimal input
   reference frequency
- add a check into zl3073x_pin_check_freq()

Let me know if you want to do it yourself or if I should do it (I would
send it along with your two patches).

Thanks,
Ivan
