The Synopsys Designware HDMI RX controller is an HDMI receiver controller that is responsible to process digital data that comes from a phy. The final result is a stream of raw video data that can then be connected to a video DMA, for example, and transfered into RAM so that it can be displayed.
The controller + phy available in this series natively support all HDMI 1.4 and HDMI 2.0 modes, including deep color. Although, the driver is quite in its initial stage and unfortunatelly only non deep color modes are supported. Also, audio is not yet supported in the driver (the controller has several audio output interfaces). Version 5 addresses review comments from Sylwester Nawrocki and Rob Herring regarding device tree bindings, messages printing levels, sleep functions and uses the new v4l2_async_subnotifier_register() function. This series depends on the patch at [1]. This series was tested in a FPGA platform.
