/*
 * DIG Encoder/Transmitter Setup
 *
 * DCE 6.0
 * - 3 DIG transmitter blocks UNIPHY0/1/2 (links A and B).
 * Supports up to 6 digital outputs
 * - 6 DIG encoder blocks.
 * - DIG to PHY mapping is hardcoded
 * DIG1 drives UNIPHY0 link A, A+B
 * DIG2 drives UNIPHY0 link B
 * DIG3 drives UNIPHY1 link A, A+B
 * DIG4 drives UNIPHY1 link B
 * DIG5 drives UNIPHY2 link A, A+B
 * DIG6 drives UNIPHY2 link B
 *
 * Routing
 * crtc -> dig encoder -> UNIPHY/LVTMA (1 or 2 links)
 * Examples:
 * 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
