imx6q porting audio codec es8316

wunlinglin — Wed, 17 Jan 2018 09:20:33 GMT

I reference porting guide - i.MX_BSP_Porting_Guide.pdf to porting audio codec - everest,es8316 on cpu-imx6q.

And I use scope to detect I2C siganl but there is nothing. I don't know I lose what in my imx6qdl-sabresd.dtsi file.

Does anyone give me a support.Thanks!

Hi Wunling

one can look at existing i.MX6Q Sabre SD wm8960 driver described in sect.28.4.1 ASoC
Driver Source Architecture attached Linux Manual and make similar audio codec es8316 driver,
based on descriptions provided in linux//Documentation/devicetree/bindings/sound/es8328.txt
linux-imx.git - i.MX Linux Kernel
and sources in linux/sound/soc/codecs/es8328.c

Best regards
igor

Hello Ling Lin,

RIght Now, I am working on ES8316 for rockpro64 board, below is my dts file snashot.

========================================================

&i2c1 {
558    i2c-scl-rising-time-ns = <300>;
559    i2c-scl-falling-time-ns = <15>;
560    status = "okay";
561
562          es8316: es8316@11 {
563                #sound-dai-cells = <0>;
564                compatible = "everest,es8316";
565                reg = <0x11>;
566                clocks = <&cru SCLK_I2S_8CH_OUT>;
567                clock-names = "mclk";
568                pinctrl-names = "default";
569                pinctrl-0 = <&i2s_8ch_mclk>;
570                hp-det-gpio = <&gpio1 RK_PB5 GPIO_ACTIVE_LOW>;
571       };
572 };

es8316-sound {
114       status = "okay";
115       compatible = "simple-audio-card";
116       simple-audio-card,format = "i2s";
117       simple-audio-card,name = "rockchip,es8316-codec";
118       simple-audio-card,mclk-fs = <256>;
119       simple-audio-card,widgets =
120             "Headphone", "Headphone Jack";
121       simple-audio-card,routing =
122             "Headphone Jack", "HPOL",
123             "Headphone Jack", "HPOR";
124       simple-audio-card,cpu {
125             sound-dai = <&i2s1>;
126       };
127       simple-audio-card,codec {
128             sound-dai = <&es8316>;
129        };
130 };

===================================================================

but i got following error:

[ 83.424483] es8316 1-0010: No sysclk provided
[ 83.425020] es8316 1-0010: ASoC: can't open codec ES8316 HiFi: -22

Can you share your

sound/soc/codecs/es8316.c

and device tree code?

Regards,
