Amlogic Meson8/8b/8m2 SoCs embed a HDMI TX PHY. Unfortunately there is no (public) documentation for this hardware. The best thing we have is the 3.10 vendor kernel, which unfortunately doesn't document most register bits (only a few are named there, the rest is all magic numbers). It is possible that this is a TranSwitch HDMI TX PHY based core, but this is pure speculation. Adding a driver for the HDMI TX PHY gets us one step closer to video output on these older SoCs.
