Hi All
I try solve problem with support SGTL5000 under Linux , ARM / ZYNQ
ARCHITECTURE. Please add this post to "alsa" forum. If you need any
others information i can send it .
My post:
I try use freescale audio chip sgtl5000 on my custom board with Zynq
chip. I need help with instance driver in device tree and debug first
execution.
1.*I use I2C* controler to configure sgtl5000 :
/ axi_iic_sgtl: i2c at 41610000 {//
// #address-cells = <1>;//
// #size-cells = <0>;//
// compatible = "xlnx,xps-iic-2.00.a";//
// interrupt-parent = <&gic>;//
// interrupts = <0 31 4>;//
// reg = <0x41610000 0x10000>;//
////
// codec: sgtl5000 at 0a {//
// #sound-dai-cells = <0>;//
// compatible = "fsl,sgtl5000";//
// reg = <0x0a>;//
////// VDDA-supply = <®_3p3v>;//
////// VDDIO-supply = <®_3p3v>;//
// clocks = <&clkc 19>;//
// }; /
How can i set comment lines ?
2. sound :
/ sound {
compatible = "fsl,imx51-babbage-sgtl5000",
"fsl,imx-audio-sgtl5000";
model = "imx51-babbage-sgtl5000";
// ssi-controller = <&ssi1>;
audio-codec = <&codec>;
audio-routing =
"MIC_IN", "Mic Jack",
"Mic Jack", "Mic Bias",
"Headphone Jack", "HP_OUT";
mux-int-port = <1>;
mux-ext-port = <3>;
};/
I want use I2C configuration driver not SPI . How can i set comment line ?
3. I2S driver looks like ok :
/ axi_i2s_adi_0: axi_i2s_adi at 77600000 {
compatible = "xlnx,axi-i2s-adi-1.0";
reg = <0x77600000 0x10000>;
xlnx,bclk-pol = <0x0>;
xlnx,dma-type = <0x1>;
xlnx,has-rx = <0x1>;
xlnx,has-tx = <0x1>;
xlnx,lrclk-pol = <0x0>;
xlnx,num-ch = <0x1>;
xlnx,s-axi-min-size = <0x000001FF>;
xlnx,slot-width = <0x18>;
};/
PS.
Right now i can compile device tree but audio is not detected.
What kind of log do you need to check Linux boot problem ?
