Disable 2rx2tx mode for AD9361

Hi,

I saw there was a initial parameter for enabling/disabling 2rx2tx mode in no_OS driver. When I disabled this parameter, AD9361 failed to be initialized (dig_tune function in driver return -5 error code). My questions are:

1) Is it possible to disable 2rx2tx mode for AD9361? or this is just for AD9364?

2) I want to set the sampling frequency of rx1 to 122.88MHz. But it seems like this is not possible if 2rx2tx mode cannot be disabled. Is this right?
