Other Parts Discussed in Thread: TLV320AIC3268, TLV320AIC3106
Tool/software: Linux
We have custom board of AM335x, and we used tlv320aic3268.
But in the SDK, driver is not there.
I used "tlv320aic3x " generic driver, and did the configuration for the same.
Here is the DTS file change
/-------------------------------------------------------------- DTS File for Sound ----------------------------------------------------------/
sound {
compatible = "simple-audio-card";
simple-audio-card,name = "AM335x-EVM";
simple-audio-card,widgets =

"Line", "Line In";
simple-audio-card,routing =
"Headphone Jack", "HPLOUT",
"Headphone Jack", "HPROUT",
"LINE1L", "Line In",
"LINE1R", "Line In";
simple-audio-card,format = "dsp_b";
simple-audio-card,bitclock-master = <&sound_master>;
simple-audio-card,frame-master = <&sound_master>;
simple-audio-card,bitclock-inversion;
simple-audio-card,cpu {
sound-dai = <&mcasp1>;
};
sound_master: simple-audio-card,codec {
/* sound-dai = <&tlv320aic3106>; */
sound-dai = <&tlv320aic3x>;
system-clock-frequency = <24000000>;
};
};
mcasp1_pins: mcasp1_pins { /* CHECK */

};
&mcasp1 {
#sound-dai-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&mcasp1_pins>;
status = "okay";
op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;

serial-dir = <

rx-num-evt = <32>;
};
i2c2_pins: pinmux_i2c2_pins {
pinctrl-single,pins = <
0x178 (PIN_INPUT_PULLUP | MUX_MODE3) /* uart1_ctsn.i2c2_sda */
0x17C (PIN_INPUT_PULLUP | MUX_MODE3) /* uart1_rtsn.i2c2_scl */
>;
};
&i2c2 {
pinctrl-names = "default";
pinctrl-0 = <&i2c2_pins>;
status = "okay";
clock-frequency = <100000>;
tlv320aic3x: tlv320aic3x@18 {
#sound-dai-cells = <0>;
compatible = "ti,tlv320aic3x";
reg = <0x18>;
status = "okay";
gpio-reset = <&gpio0 15 GPIO_ACTIVE_LOW>;
/* Regulators */
AVDD-supply = <&vaux2_reg>;
IOVDD-supply = <&vaux2_reg>;
DRVDD-supply = <&vaux2_reg>;
DVDD-supply = <&vbat>;
};
};
/-------------------------------------------------------------------------------------------------------------------------------------------------------------------/
Than driver is loaded perfectly.
I did the change for i2c resister according to tlv320aic2368.
But still not getting audio.
Please provide the driver of tlv320aic2368 or provide some solution for the same.
