Basically D-PHY is integrated inside MIPI-DSI Tx module. MIPI-DSI Tx module consists of MIPI DSI-2 Host controller (LINK) and MIPI D-PHY Tx(D-PHY). That is the reason I have modelled like this.

Please let me know. I don't know the details of the h/w so I can't say. We do see blocks with a phy modeled as 1 block only to need to separate them when the phy part changes in the next process node. I imagine we have it done both ways for DSI + D-PHY. Rob
