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.
Note: the changes in the TDA998x I2C driver are based on my previous
patch series:

- v2
- add ACLK setting and code optimization in patch 1
- from Mark Brown's remarks in patch 2:
- don't compile the codec when CONFIG_ALL_CODECS
- simplify the code about start/stop audio
- fix coding style errors
- add audio-port-names associated to audio-ports
- add audio-port-names in patch 4
- add patch 5 'adjust the audio CTS_N pre-divider from audio format'
for the Beaglebone-Black board (Jyri Sarha)
