HI all:
Just now we want to use the tlv320aic3120 for audio playback on the am5728 custom board.
When we configured the devicetree, the kernel will reporter error like below
## aic31xx_set_dai_sysclk: clk_id = 0, freq = 22579200, dir = 0
tlv320aic31xx-codec 0-0018: aic31xx_set_dai_sysclk: Unsupported frequency 22579200
My devicetree is like below:
sound0: sound@0 {
compatible = "simple-audio-card";
simple-audio-card,name = "custom";
simple-audio-card,widgets =
"Headphone", "Headphone Jack",
"Speaker", "Speaker";
simple-audio-card,routing =
"Headphone Jack", "HPL",
"Headphone Jack", "HPR",
"Speaker", "SPL",
"Speaker", "SPR";
simple-audio-card,format = "i2s";
simple-audio-card,bitclock-master = <&sound0_master>;
simple-audio-card,frame-master = <&sound0_master>;
simple-audio-card,cpu {
sound-dai = <&mcasp3>;
};
sound0_master: simple-audio-card,codec {
sound-dai = <&tlv320aic3120>;
clocks = <&clkout2_clk>;
};
};
tlv320aic3120: tlv320aic3120@18 {
#sound-dai-cells = <0>;
compatible = "ti,tlv320aic3120";
reg = <0x18>;
assigned-clocks = <&clkoutmux2_clk_mux>;
assigned-clock-parents = <&sys_clk2_dclk_div>;
adc-settle-ms = <40>;
SPRVDD-supply = <&vdd_3v3>;
SPLVDD-supply = <&vdd_3v3>;
AVDD-supply = <&vdd_3v3>;
IOVDD-supply = <&vdd_3v3>;
DRVDD-supply = <&vdd_3v3>;
DVDD-supply = <&aic_dvdd>;
status = "okay";
};
in the hardware, we used the pin clkout2 to generate the mclk to tlv320aic3120?
So how can we change the clkout2 to 12MHZ or 24MHZ in the devicetree
Thanks
regards
