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.
