The Atmel SSC is currently not usable as an audio DAI unless someone registers it with ASoC. This is currently delegated to a platform driver for every possible audio use, and prevents the SSC from being used as a cpu DAI with the simple-audio-card driver. The first patch fixes this. The second patch simplifies one of these platform drivers, since it can now rely on the SSC to register itself with ASoC. However, this may not be a possible simplification for other, older, drivers since it also requires device tree changes. Cheers, Peter Peter Rosin (2): misc: atmel-ssc: register as sound DAI if #sound-dai-cells is present ASoC: atmel: tse850: rely on the ssc to register as a cpu dai by itself .../devicetree/bindings/misc/atmel-ssc.txt | 2 + .../bindings/sound/axentia,tse850-pcm5142.txt | 11 +++-- drivers/misc/atmel-ssc.c | 50 ++++++++++++++++++++++ include/linux/atmel-ssc.h | 1 + sound/soc/atmel/tse850-pcm5142.c | 23 ++-------- 5 files changed, 64 insertions(+), 23 deletions(-) -- 2.1.4
