[PATCH 0/2] phy: Add support for the HDMI TX PHY on Meson8/8b/8m2

[Martin Blumenstingl <martin.blumenstingl@googlemail.com>]

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.
