tlv320aic3204 codec probe issue.

Hello folks,

I am working on the imx8mp custom board. tlv320aic3204 codec is connected to imx8mp over the I2C4 and SAI5 interface.

Here are my dts file changes :

sound { compatible = "simple-audio-card"; label = "tlv320aic32x4-audio"; simple-audio-card,name = "tlv320aic32x4"; simple-audio-card,format = "i2s"; status = "okay"; simple-audio-card,frame-master = <&sndcodec>; simple-audio-card,bitclock-master = <&sndcodec>; simple-audio-card,widgets = "Microphone", "Mic Jack", "Line", "Line In", "Line", "Line Out", "Headphone", "Headphone Jack"; simple-audio-card,routing = "IN1_L", "Line In", "IN1_R", "Line In", "IN3_R", "Mic Jack", "CM_L", "Mic Jack", "CM_R", "Mic Jack", "Line Out", "LOL", "Line Out", "LOR", "Headphone Jack", "HPL", "Headphone Jack", "HPR"; simple-audio-card,dai-link { format = "i2s"; cpu: simple-audio-card,cpu { sound-dai = <&sai5>; }; sndcodec: codec { sound-dai = <&tlv320aic32x4>; system-clock-frequency = <IMX8MP_CLK_AUDIO_BLK_CTRL_SAI5_MCLK1>; /* this matches sai3 */ }; }; }; &sai5 { #sound-dai-cells = <0>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_sai5>; dmas = <&sdma2 8 24 0>, <&sdma2 9 24 0>; assigned-clocks = <&clk IMX8MP_CLK_SAI5>; assigned-clock-parents = <&clk IMX8MP_AUDIO_PLL1_OUT>; assigned-clock-rates = <24576000>; clocks = <&audio_blk_ctrl IMX8MP_CLK_AUDIO_BLK_CTRL_SAI5_IPG>, <&clk IMX8MP_CLK_DUMMY>, <&audio_blk_ctrl IMX8MP_CLK_AUDIO_BLK_CTRL_SAI5_MCLK1>, <&clk IMX8MP_CLK_DUMMY>, <&clk IMX8MP_CLK_DUMMY>, <&clk IMX8MP_AUDIO_PLL1_OUT>, <&clk IMX8MP_AUDIO_PLL2_OUT>; clock-names = "bus", "mclk0", "mclk1", "mclk2", "mclk3", "pll8k", "pll11k"; fsl,sai-asynchronous; fsl,dataline = <2 0xf 0xf>; status = "okay"; }; pinctrl_sai5:sai5grp { fsl,pins = < MX8MP_IOMUXC_SAI5_MCLK__AUDIOMIX_SAI5_MCLK 0xd6 MX8MP_IOMUXC_SAI5_RXD0__AUDIOMIX_SAI5_RX_DATA00 0xd6 MX8MP_IOMUXC_SAI5_RXFS__AUDIOMIX_SAI5_RX_SYNC 0xd6 MX8MP_IOMUXC_SAI5_RXC__AUDIOMIX_SAI5_RX_BCLK 0xd6 MX8MP_IOMUXC_SAI5_RXC__AUDIOMIX_SAI1_TX_DATA01 0xd6 >; }; &i2c4 { clock-frequency = <384000>; pinctrl-names = "default", "gpio"; pinctrl-0 = <&pinctrl_i2c4>; pinctrl-1 = <&pinctrl_i2c4_gpio>; scl-gpios = <&gpio5 20 (GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN)>; sda-gpios = <&gpio5 21 (GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN)>; status = "okay"; tlv320aic32x4: tlv320aic32x4@18 { #sound-dai-cells=<0>; compatible = "ti,tlv320aic32x4"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_tlv320aic3x04>; reg = <0x18>; clock-names = "mclk"; clocks = <&audio_blk_ctrl IMX8MP_CLK_AUDIO_BLK_CTRL_SAI5_MCLK1>; iov-supply = <&reg_vcc_1v8>; ldoin-supply = <&reg_vcc_3v3>; reset-gpios = <&gpio5 11 GPIO_ACTIVE_LOW>; }; }; pinctrl_tlv320aic3x04: tlv320aic3x04grp { fsl,pins = < /* CODEC RST# */ MX8MP_IOMUXC_ECSPI2_MOSI__GPIO5_IO11 0x180 >; };

With the above dts changes I am getting the below error logs:

Can someone see what I’m doing wrong or what I’m missing?

Hope you are doing well; I will be working in your support case.

The TLV320AIC3100 audio CODEC is not supported by default on our BSP. To use this CODEC to your system, you need to add a third-party driver provided by Texas Instruments and configure your device tree.

Unfortunately, there is no a guide to port this specific CODEC to the BSP. The references we have are the i.MX porting guide and EVK device tree (WM8960).

Maybe this thread could be helpful.

Best regards.
