The TDA998x HDMI transmitter accepts audio input from either I2S or S/PDIF. Theses inputs have different intrinsic constraints and these constraints may be modified by the audio parameters of the connected video device. The choice of I2S or S/PDIF may be the done by the user or by automatic processing (DPCM?) at each audio starting time. This asks for a dynamic audio input switch in the HDMI driver. This patch series implements the TDA998x specific CODEC. A simple function call mechanism is used for exchanges between the CODEC and the HDMI driver.
