* DIG Encoder/Transmitter Setup

* DCE 3.0/3.1

* Supports up to 3 digital outputs
* - 2 DIG encoder blocks.
* DIG1 can drive UNIPHY link A or link B
* DIG2 can drive UNIPHY link B or LVTMA

* DCE 3.2
* - 3 DIG transmitter blocks. UNIPHY0/1/2 (links A and B).

* DIG1/2 can drive UNIPHY0/1/2 link A or link B

* crtc0 -> dig2 -> LVTMA links A+B -> TMDS/HDMI
* crtc1 -> dig1 -> UNIPHY0 link B -> DP
* crtc0 -> dig1 -> UNIPHY2 link A -> LVDS
* crtc1 -> dig2 -> UNIPHY1 link B+A -> TMDS/HDMI
