drm/bridge/sii8620: rewrite hdmi start sequence
...
MHL3 protocol requires registry adjustments depending on chosen video mode.
Necessary information is gathered in mode_fixup callback. In case of HDMI
video modes driver should also send special AVI and MHL3 infoframes.
The patch introduces generic helpers for handling MHL3 infoframes, in
case of appearance of other users of MHL3 infoframes these function can
be moved to common library.

drm/bridge/sii8620: initial support for eCBUS-S mode
...
The Single-ended eCBUS Mode (eCBUS-S) mode provides 60 Mb/s full-duplex
bidirectional traffic for three channels:
- CBUS data (CBUS1 channel),
- High-bandwidth MHL data (eMSC channel),
- tunneling data (T-CBUS channel).
It is required to fully support MHL3 dongles.

drm/bridge: add Silicon Image SiI8620 driver
...
SiI8620 transmitter converts eTMDS/HDMI signal to MHL 3.0.
It is controlled via I2C bus. Its interaction with other
devices in video pipeline is performed mainly on HW level.
The only interaction it does on device driver level is
filtering-out unsupported video modes, it exposes drm_bridge
interface to perform this operation.
