[PATCH v3 0/5] add a TDA998x CODEC

[Jean-Francois Moine]

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:

- v3
	- move the DT description of the CODEC as a subnode of the
	  TDA998x I2C (Mark Brown remark - is this the right way?)
		- change CODEC loading mechanism
		- simplify tda998x i2c reference search
		- CODEC DT documentation in drm/i2c/tda998x.txt

- 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)
