Hi,
I found this url Porting WM8960 to Android jb4.2.2 about porting the wm8960 in android (kernel version is 3.0.35)
but in yocto 1.6.2 that is using device tree and 3.10.53 kernel.
I try port it, but the AUD3_TXD still not output any signal.
the following is my device tree for sound part:
| sound { | |
| | compatible = "fsl,imx-audio-wm8960"; | |
| | model = "wm8960-audio"; | |
| | cpu-dai = <&ssi2>; | |
| | audio-codec = <&codec>; | |
| | codec-master; | |
| | gpr = <&gpr>; | |
| | audio-routing = | |
| | | "Headset Jack", "HP_L", |
| | | "Headset Jack", "HP_R", |
| | | "Ext Spk", "SPK_LP", |
| | | "Ext Spk", "SPK_LN", |
| | | "Ext Spk", "SPK_RP", |
| | | "Ext Spk", "SPK_RN"; |
| | hp-det = <3 1>; | |
| | hp-det-gpios = <&gpio7 8 0>; | |
| | mic-det-gpios = <&gpio1 9 0>; | |
| }; | |
| codec: wm8960@1a { |
| | compatible = "wlf,wm8960"; |
| | reg = <0x1a>; |
| | status = "okay"; |
| | clocks = <&clks 201>; |
| | clock-names = "mclk"; |
| | wlf,shared-lrclk; |
};
&audmux {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_audmux_wcp>;
status = "okay";
ssi2 {
fsl,audmux-port = <MX31_AUDMUX_PORT2_SSI1>;
fsl,port-config = <
(IMX_AUDMUX_V2_PTCR_TFSDIR |
IMX_AUDMUX_V2_PTCR_SYN |
IMX_AUDMUX_V2_PTCR_TFSEL(MX31_AUDMUX_PORT3_SSI_PINS_3) |
IMX_AUDMUX_V2_PTCR_TCLKDIR |
IMX_AUDMUX_V2_PTCR_TCSEL(MX31_AUDMUX_PORT3_SSI_PINS_3))
IMX_AUDMUX_V2_PDCR_RXDSEL(MX31_AUDMUX_PORT3_SSI_PINS_3)
>;
};
aud3 {
fsl,audmux-port = <MX31_AUDMUX_PORT3_SSI_PINS_3>;
fsl,port-config = <
IMX_AUDMUX_V2_PTCR_SYN
IMX_AUDMUX_V2_PDCR_RXDSEL(MX31_AUDMUX_PORT2_SSI1)
>;
};
};
Dose any one have idea about this?
Thanks,
ChuYuan
