From: Tomi Valkeinen <tomi.valkeinen@xxxxxx> J721E common processor board can be interfaced with the infotainment expansion board[0] to enable the following audio/video interfaces in addition to the peripherals provided by the common processor board: - Two Audio codecs each with three Stereo Inputs and four Stereo Outputs - Audio input over FPD Link III - Digital Audio Interface TX/RX - HDMI/FPD LINK III Display out - LI/OV Camera input Add support for TFP410 HDMI bridge located on the Infotainment Expansion Board (connected to J46 & J51). Add a HDMI connector node and connect the endpoints as below: DSS => TFP410 bridge => HDMI connector Also add the pinmux data and board muxes for DPI.
