Subject: [PATCH v7 0/2] ASoC: tda998x: add a codec to the HDMI transmitter

The NXP TDA998x HDMI transmitter may transmit audio to the HDMI link
from 2 different sources, I2S and S/PDIF.

This patch set adds an interface between the HDMI transmitter and
the HDMI CODEC.

The interface is used by the TDA998x driver to update the audio
constraints from the display characteristics (EDID) and by the audio
subsystem to connect the chosen audio source to the HDMI link.

v7:
	- remove the change of the K predivider (Jyri Sarha)
	- add S24_3LE and S32_LE as possible audio formats (Jyri Sarha)
	- don't move the struct priv2 definition and use the
	  slave encoder private data as the device private data
	  (Russell King)
	- remove the useless request_module (Russell King/Mark Brown)
	- don't lock the HDMI module (Russell King)
	- use platform_device_unregister to remove the codec
	  (Russell King)
v6:
	- extend the HDMI CODEC instead of using a specific CODEC
v5:
	- use the TDA998x private data instead of a specific area
	  for the CODEC interface
	- the CODEC is TDA998x specific (Mark Brown)
v4:
	- remove all the TDA998x specific stuff from the CODEC
	- move the EDID scan from the CODEC to the TDA998x
	- move the CODEC to sound/soc (Mark Brown)
	- update the audio_sample_rate from the EDID (Andrew Jackson)
v3: fix bad rate (Andrew Jackson)
v2: check double stream start (Mark Brown)
