基于飞凌imx6q的高版本uboot和内核移植（四、wm8960移植）

6.6.52的内核设备树默认开的wm8962，开发板上用的是wm8960，内核默认是打开wm8960驱动的，下面修改设备树

按下面修改imx6qdl-sabresd.dtsi文件：

&i2c1 { clock-frequency = <100000>; pinctrl-names = "default"; //pinctrl-names = "default", "gpio"; pinctrl-0 = <&pinctrl_i2c1>; //pinctrl-1 = <&pinctrl_i2c1_gpio>; //scl-gpios = <&gpio5 27 GPIO_ACTIVE_HIGH>; //sda-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH>; status = "okay"; codec: wm8962@1a { compatible = "wlf,wm8962"; reg = <0x1a>; clocks = <&clks IMX6QDL_CLK_CKO>; DCVDD-supply = <&reg_audio>; DBVDD-supply = <&reg_audio>; AVDD-supply = <&reg_audio>; CPVDD-supply = <&reg_audio>; MICVDD-supply = <&reg_audio>; PLLVDD-supply = <&reg_audio>; SPKVDD1-supply = <&reg_audio>; SPKVDD2-supply = <&reg_audio>; gpio-cfg = < 0x0000 /* 0:Default */ 0x0000 /* 1:Default */ 0x0013 /* 2:FN_DMICCLK */ 0x0000 /* 3:Default */ 0x8014 /* 4:FN_DMICCDAT */ 0x0000 /* 5:Default */ >; status = "disabled"; }; codec2: wm8960@1a { compatible = "wlf,wm8960"; reg = <0x1a>; clocks = <&clks IMX6QDL_CLK_CKO>; DCVDD-supply = <&reg_audio>; DBVDD-supply = <&reg_audio>; AVDD-supply = <&reg_audio>; CPVDD-supply = <&reg_audio>; MICVDD-supply = <&reg_audio>; PLLVDD-supply = <&reg_audio>; SPKVDD1-supply = <&reg_audio>; SPKVDD2-supply = <&reg_audio>; clock-names = "mclk"; VDD-supply = <&reg_audio>; wlf,shared-lrclk; status = "disabled"; }; };

按下面修改imx6qdl-sabresd.dts文件：

&codec2 { status = "okay"; }; &mx6sound { compatible = "fsl,imx6q-sabresd-wm8960", "fsl,imx-audio-wm8960"; model = "wm8960-audio"; audio-codec = <&codec2>; audio-routing = "Headphone Jack", "HP_L", "Headphone Jack", "HP_R", "Ext Spk", "SPK_RP", "Ext Spk", "SPK_RN", "Ext Spk", "SPK_LP", "Ext Spk", "SPK_LN", "AMIC", "MICB", "LINPUT1", "AMIC", "LINPUT2", "AMIC", "RINPUT1", "AMIC", "RINPUT2", "AMIC", "LINPUT3", "AMIC", "RINPUT3", "AMIC", "DMIC", "MICB", "LINPUT1", "DMIC", "LINPUT2", "DMIC", "RINPUT1", "DMIC", "RINPUT2", "DMIC", "CPU-Playback", "ASRC-Playback", "Playback", "CPU-Playback", "ASRC-Capture", "CPU-Capture", "CPU-Capture", "Capture"; hp-det-gpios = <&gpio7 8 GPIO_ACTIVE_LOW>; //hp-det-gpios = <&gpio7 8 0>; };

进入文件系统后： dmesg | grep -E "wm8960|soc-audio|asoc"
[ 5.391847] #0: wm8960-audio

到此wm8960移植完毕
