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.

Jean-Francois Moine (4):
  drm/i2c: tda998x: add a function for dynamic audio input switch
  ASoC: tda998x: add a codec driver for TDA998x
  ASoC: tda998x: add DT documentation
  ASoC: tda998x: adjust the audio hw parameters from EDID
