Hi, 

On our project we need to enable BB retimer TX compliance test mode for certification, and Intel guidance is that this is done through the PD controller. It looks like there is an undocumented interface to communicate with the retimer in the user defined register space. How do we enable this functionality? 

This is using the host sdk CYPD5225-96BZXI_notebook_tbt project for tiger lake.

For anyone else. Revision O of the HPI specification has all the information needed to implement this, and was not part of the specification before this revision.
