[imx8qxp][linux][adau1761] Fail to porting adau1761 codec to imx8qxpm.

[WolsYang]

Hi NXP,

I am trying to port adau1761 to imx8qxp, but get fail when yocto do_copile.

Reference to non-existent node or label "adau1761"

The kernel version is 5.15.

I have already added node "adau1761" like below in imx8x-mek.dtsi.

Please help me :'(

/{

....

sound-adau1761 {

compatible = "simple-audio-card";

simple-audio-card,name = "adau1761-Sound-Card";

simple-audio-card,format = "left_j";

simple-audio-card,bitclock-master = <&codec_dai>;

simple-audio-card,frame-master = <&codec_dai>;

simple-audio-card,widgets =

"Microphone", "Microphone Jack",

"Headphone", "Headphone Jack",

"Speaker", "External Speaker";

simple-audio-card,routing =

"MIC_IN", "Microphone Jack",

"Headphone Jack", "HP_OUT",

"External Speaker", "LINE_OUT";

cpu_dai: simple-audio-card,cpu {

sound-dai = <&sai1>;

};

codec_dai: simple-audio-card,codec {

sound-dai = <&adau1761>;

clocks = <&mclkout0_lpcg 0>;

};

};

&cm40_i2c {

       ...

adau1761: adau1761@3b {

compatible = "adi,adau1761";

reg = <0x3b>;

clocks = <&mclkout0_lpcg 0>;

clock-names = "mclk";

assigned-clocks = <&clk IMX_SC_R_AUDIO_PLL_0 IMX_SC_PM_CLK_PLL>,

<&clk IMX_SC_R_AUDIO_PLL_0 IMX_SC_PM_CLK_SLV_BUS>,

<&clk IMX_SC_R_AUDIO_PLL_0 IMX_SC_PM_CLK_MST_BUS>,

<&mclkout0_lpcg 0>;

};

};

The problem is because some *-rpmsg.dts delete "cm40_i2c" node.

You have to fix it your way.
