[PATCH v3 0/5] add a TDA998x CODEC

From: Jean-Francois Moine
Date: Sat Feb 01 2014 - 12:32:39 EST


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)

Jean-Francois Moine (5):
drm/i2c: tda998x: add a function for dynamic audio input switch
ASoC: tda998x: add a codec driver for the TDA998x
ASoC: tda998x: add DT documentation of the tda998x CODEC
ASoC: tda998x: adjust the audio hw parameters from EDID
ASoC: tda998x: adjust the audio CTS_N pre-divider from audio format
