Hi !

I have built a tiny linux with Yocto (kernel rockhip_linux v4.4) and added a node for the codec es8388 and another for the rockhip_hdmi_analog driver in rk3288-firefly.dtsi. But during the boot, communications with the codec on the I2C2 end with a timeout 'rk3x-i2c ff660000.i2c: timeout, ipd: 0x00, state: 1'.  
Then I measured the voltage on the codec's pins and it appeared that it is not powered.
I didn't change anything in the dtsi concerning the PMU...

Here are the changes I made in the dtsi file :

.
.
.
sound0: sound@0 {
                compatible = "simple-audio-card";
                simple-audio-card,name = "SPDIF";
                simple-audio-card,dai-link@1 {
                        cpu { sound-dai = <&spdif>; };
                        codec { sound-dai = <&spdif_out>; };
                };
        };

sound1: sound@1 {
                compatible = "rockchip,rk3288-hdmi-analog";
                rockchip,model = "Analog audio output";
                rockchip,i2s-controller = <&i2s>;
                rockchip,audio-codec = <&codec>;
                rockchip,routing = "Analog", "LOUT2",
                                   "Analog", "ROUT2";
                rockchip,hp-det-gpios = <&gpio7 15 GPIO_ACTIVE_HIGH>;
                rockchip,hp-en-gpios = <&gpio0 10 GPIO_ACTIVE_HIGH>;
                pinctrl-names = "default";
                pinctrl-0 = <&phone_ctl>, <&hp_det>;
        };

spdif_out: spdif-out {
                compatible = "linux,spdif-dit";
                #sound-dai-cells = <0>;
        };
.
.
.

&i2c2 {
    status = "okay";

    codec: es8328@10 {
        compatible = "everest,es8328";
        DVDD-supply = <&vcca_33>;
        AVDD-supply = <&vcca_33>;
        PVDD-supply = <&vcca_33>;
        HPVDD-supply = <&vcca_33>;
        clocks = <&cru HCLK_I2S0>, <&cru SCLK_I2S0>;
        clock-names = "i2s_hclk", "i2s_clk";
        reg = <0x10>;
    };
/*
    codec: es8323@10 {
        compatible = "everest,es8323";
        reg = <0x10>;
        spk-con-gpio = <&gpio0 RK_PB2 GPIO_ACTIVE_HIGH>;
        hp-det-gpio = <&gpio7 RK_PB7 GPIO_ACTIVE_HIGH>;
        hp-mic-only = <1>;
        clocks = <&cru HCLK_I2S0>, <&cru SCLK_I2S0>;
        clock-names = "i2s_hclk", "i2s_clk";
        pinctrl-names = "default";
    };
*/

};
What did I do wrong ? Did someone manage to have audio working with yocto on this board ?

Any help would be appreciated !

Yes, I thought it was an es8323 but there is "ES8388" written on the chip.

I found that the node for the ACT8846 in the DTSI did not match the datasheet of the reload core board. So I changed it to :

     act8846: act8846@5a {
                compatible = "active-semi,act8846";
                reg = <0x5a>;
                pinctrl-names = "default";
                pinctrl-0 = <&pmic_vsel>, <&pwr_hold>;
                system-power-controller;

                vp1-supply = <&vcc_sys>;
                vp2-supply = <&vcc_sys>;
                vp3-supply = <&vcc_sys>;
                vp4-supply = <&vcc_sys>;
                inl1-supply = <&vcc_sys>;
                inl2-supply = <&vcc_sys>;
                inl3-supply = <&vcc_20>;

                regulators {
                        vcc_ddr: REG1 {
                                regulator-name = "vcc_ddr";
                                regulator-min-microvolt = <1200000>;
                                regulator-max-microvolt = <1200000>;
                                regulator-always-on;
                        };

                        vcc_io: REG2 {
                                regulator-name = "vcc_io";
                                regulator-min-microvolt = <3300000>;
                                regulator-max-microvolt = <3300000>;
                                regulator-always-on;
                        };

                        vdd_log: REG3 {
                                regulator-name = "vdd_log";
                                regulator-min-microvolt = <1100000>;
                                regulator-max-microvolt = <1100000>;
                                regulator-always-on;
                        };

                        vcc_20: REG4 {
                                regulator-name = "vcc_20";
                                regulator-min-microvolt = <2000000>;
                                regulator-max-microvolt = <2000000>;
                                regulator-always-on;
                        };

                        vccio_sd: REG5 {
                                regulator-name = "vccio_sd";
                                regulator-min-microvolt = <3300000>;
                                regulator-max-microvolt = <3300000>;
                                regulator-always-on;

                                regulator-always-on;
                        };

                        vcca_33: REG7 {
                                regulator-name = "vcca_33";
                                regulator-min-microvolt = <3300000>;
                                regulator-max-microvolt = <3300000>;
                                regulator-always-on;
                        };

                        vcc_lan: REG8 {
                                regulator-name = "vcc_lan";
                                regulator-min-microvolt = <3300000>;
                                regulator-max-microvolt = <3300000>;
                                regulator-always-on;
                        };

                        vccio_pmu: REG9 {
                                regulator-name = "vcca_18";
                                regulator-min-microvolt = <1800000>;
                                regulator-max-microvolt = <1800000>;
                        };


                        vdd_10: REG10 {
                                regulator-name = "vdd_10";
                                regulator-min-microvolt = <1000000>;
                                regulator-max-microvolt = <1000000>;
                                regulator-always-on;
                        };

                        vccio_wl: vcc_18: REG11 {
                                regulator-name = "vcc_18";
                                regulator-min-microvolt = <1800000>;
                                regulator-max-microvolt = <1800000>;
                                regulator-always-on;
                        };

                        vcc18_lcd: REG12 {
                                regulator-name = "vcc18_lcd";
                                regulator-min-microvolt = <1800000>;
                                regulator-max-microvolt = <1800000>;
                                regulator-always-on;
                        };
                };
        };

Now, I have the correct voltage on the codec's pins... but still no audio

Hi, I have checked with my workmate, Yes,  the es8323 and es8388  can both  work fine with the same software. you need modify nothing.
does it have the audio when flash the android image.

I do have audio with the android image.
Does it means that I have to use original drivers : compatible es8323 for the codec, and compatible rk3368-hdmi-analog for the hdmi/audio codec driver  ?
