Hi everyone,
I'm using a board equiped with IMX6 dual Lite, with codec sgtl5000, clk01
(on GPIO_0) is used as master clock for the sgtl5000.
The build system is yocto on branch krogoth
With linux-imx, everything was fine.
then I switched to Linux-fslc, now the sgtl5000 is not detected anymore, I
could see that the clock is not generated anymore...
I checked the i2c control signals, everything is fine on the bus, but as
the master clock is not available, the chip doesn't answer...
So now the sgtl 5000 is not detected anymore on the I2C bus
My question is :
How can I get this clock generated/activated? maybe something is missing in
my devicetree but as I didn't modified it I don't know what it could be.
Thanks for any help
Aurele
I joined the content of /sys/kernel/debug/clk/clk_summary file. I saw that
CKO clocks are not active at all
below some pieces of my devicetree :
&i2c2 {
status = "okay";
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c2_moniteur>;
codec: sgtl5000 at 0a {
compatible = "fsl,sgtl5000";
reg = <0x0a>;
clocks = <&clks 201>;
VDDA-supply = <®_3p3v>;
VDDIO-supply = <®_3p3v>;
};
};
&ssi1 {
fsl,mode = "i2s-slave";
status = "okay";
};
sound {
compatible = "fsl,imx6dl-moniteur-sgtl5000", "fsl,imx-audio-sgtl5000";
model = "imx6dl-moniteur-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>;
};
