Jie Qiu 56ba355d6b drm/mediatek: enable hdmi output control bit
MT8173 HDMI hardware has a output control bit to enable/disable HDMI
output. Because of security reason, so this bit can ONLY be controlled
in ARM supervisor mode. Now the only way to enter ARM supervisor is the
ARM trusted firmware. So atf provides a API for HDMI driver to call to
setup this HDMI control bit to enable HDMI output in supervisor mode.

Jie Qiu 8f83f26891 drm/mediatek: Add HDMI support
This patch adds drivers for the HDMI bridge connected to the DPI0
display subsystem function block, for the HDMI DDC block, and for
the HDMI PHY to support HDMI output.
This includes an interface to the generic hdmi-codec driver to start
or stop audio playback and to retrieve ELD (EDID like data) to limit the
supported audio formats to the HDMI sink capabilities.
