How to start ssc0

Fri Jan 03, 2014 10:32 am

When I start the linux in SAMA5D3* , some errors appear :

wm8904 0-001a: revision A
ssc: ssc0 platform device is missing
Unable to parent ASoC SSC DAI on SSC: -19
sama5d3ek-audio sound.5: failed to set SSC 0 for audio

I modify sama5d3mb.dtsi like this
i2c1: i2c@f0018000 {
wm8904: wm8904@1a {
compatible = "wm8904";
reg = <0x1a>;
ssc0: ssc@f0008000 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ssc0_tx &pinctrl_ssc0_rx>;
status = "okey";
sound {
compatible = "atmel,sama5d3ek-wm8904";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pck0_as_audio_mck>;

atmel,model = "wm8904 @ SAMA5D3EK";
atmel,audio-routing =
"Headphone Jack", "HPOUTL",
"Headphone Jack", "HPOUTR",
"IN2L", "Line In Jack",
"IN2R", "Line In Jack",
"IN1L", "Mic";

atmel,ssc-controller = <&ssc0>;
atmel,audio-codec = <&wm8904>;

and sama5d3.dtsi is never changed.
why my ssc0 do not work? Request for help
