Linux/TLV320AIC3105: tlv320aic3105 playback hangs

Hi, Bruce,

Unfortunately we don't have active Linux support, the only available Linux codes are mentioned in this post. My colleague in charge of the '3105 has been notified about your question, maybe he can could provide more information.

Hi Diego,

Thanks for sending me the link, but my question is why tlv320aic3105 is busy when probing using i2cdetect -r 0x18, it indicates that it is busy, I have to force to change the values of registers. Here is the device tree for supporting aic3105:

mcasp0_pins_default: mcasp0_pins_default {
pinctrl-single,pins = <

0x190 ( PIN_OUTPUT | MUX_MODE0 ) /* refer to BBB audio cape*/
0x194 ( PIN_OUTPUT | MUX_MODE0 )
0x198 ( PIN_INPUT | MUX_MODE0 ) /* (D12) mcasp0_axr0.mcasp0_axr0 */
0x19c ( PIN_OUTPUT | MUX_MODE2 ) /* (C12) mcasp0_ahclkr.mcasp0_axr2 */

0x86c ( PIN_OUTPUT_PULLDOWN | MUX_MODE7) /* gpmc_a11.GPIO1_27 */

>;
};

/* Optional sleep pin settings. Must manually enter values in the below skeleton. */
mcasp0_pins_sleep: mcasp0_pins_sleep {
pinctrl-single,pins = <
0x190 ( PIN_INPUT_PULLDOWN | MUX_MODE7 ) /* (A13) mcasp0_aclkx.mcasp0_aclkx */
0x194 ( PIN_INPUT_PULLDOWN | MUX_MODE7 ) /* (B13) mcasp0_fsx.mcasp0_fsx */
0x198 ( PIN_INPUT_PULLDOWN | MUX_MODE7 ) /* (D12) mcasp0_axr0.mcasp0_axr0 */
0x19c ( PIN_INPUT_PULLDOWN | MUX_MODE7 ) /* (C12) mcasp0_ahclkr.mcasp0_axr2 */

0x86c ( PIN_INPUT_PULLDOWN | MUX_MODE7) /* gpmc_a11.GPIO1_27 */
>;
};


i2c2_pins: pinmux_i2c2_pins {
pinctrl-single,pins = <
0x178 0x73
0x17c 0x73
/* 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 {
compatible = "ti,tlv320aic3x";
reg = <0x18>;
status = "okay";
};
};

&mcasp0 {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mcasp0_pins_default>;
pinctrl-1 = <&mcasp0_pins_sleep>;
status = "okay";

op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;
num-serializer = <16>;
serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
0 2 1 0
0 0 0 0
0 0 0 0
0 0 0 0
>;
tx-num-evt = <1>;
rx-num-evt = <1>;
};

/ {
clk_mcasp0_fixed: clk_mcasp0_fixed {
#clock-cells = <0>;
compatible = "fixed-clock";
clock-frequency = <24576000>;
};

clk_mcasp0: clk_mcasp0 {
#clock-cells = <0>;
compatible = "gpio-gate-clock";
clocks = <&clk_mcasp0_fixed>;
enable-gpios = <&gpio1 27 0>; /* change back, BG 05/10/17 */
};

sound {
compatible = "ti,da830-evm-audio";
ti,model = "DA830 EVM";
ti,audio-codec = <&tlv320aic3x>;
ti,mcasp-controller = <&mcasp0>;
ti,audio-routing =
"Headphone Jack", "HPLOUT",
"Headphone Jack", "HPROUT";

clocks = <&clk_mcasp0_fixed>;
clock-names = "mclk";
};

I made those changes on am335x-bonegreen.dts and am335x-bone-common.dtsi, then compile them from TI processor SDK (ti-processor-sdk-linux-am335x-evm-03.02.00.05)

I don't know where it goes wrong.

Hi, Bruce,

Unfortunately, we are not providing support to linux drivers. All the information that we have about linux drivers is located in the link that my colleague provided.
