Hi Mark Brown,
Now, I am trying to move atmel audio part to DT support. I meet the
following issue.
Atmel audio part has three platform device:
-> atmel ssc: ssc library (different SOC has different number)
-> atmel ssc dai: dai for audio
-> atmel pcm: for pdc or dma transfer (now only support pdc, dma
support will add soon)
In DT support kernel, I don't find any similar case. So, if I want to
keep ssc as library, and use dai to register pcm. Then the dts file will
like:
---<8---
ssc0: ssc@fffbc000 {
status = "okay";
};
dai0: dai {
compatible = "atmel,atmel-ssc-dai";
};
sound {
compatible = "atmel,at91sam9g20-audio";
atmel,model = "wm8731 @ sam9g20ek";
atmel,audio-routing =
"Ext Spk", "LHPOUT",
"Int Mic", "MICIN";
atmel,audio-codec = <&wm8731>;
atmel,dai = <&dai>;
};
--->8---
Would this be OK?
If not, may I add some code for ssc which dedicate for audio into
sound/soc/atmel (using audio-ssc and ssc to distiguish which dedicate
for audio, which used for ssc library)? This will broken the exist code
for audio (only sam9g20-wm8731).
Any suggestion?
