The implementation is mainly based on the downstream driver, ported to the generic HDMI Codec framework [1] recently merged in the DRM tree. The parameters computation has been kept as is and the data stored in the dw_hdmi_qp struct as been cleaned up. The downstream kernel also implements a machine driver for HDMI audio but it is doing exactly what the simple-audio-card driver does, so use that instead in the ROCK 5B device tree.
