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: http://lists.freedesktop.org/archives/dri-devel/2014-January/052837.html - 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 .../devicetree/bindings/drm/i2c/tda998x.txt | 17 ++ drivers/gpu/drm/i2c/tda998x_drv.c | 86 +++++- include/drm/i2c/tda998x.h | 11 +- sound/soc/codecs/Kconfig | 6 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tda998x.c | 303 +++++++++++++++++++++ 6 files changed, 419 insertions(+), 6 deletions(-) create mode 100644 sound/soc/codecs/tda998x.c -- 1.9.rc1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
