MX6 Android的显示要设置为hdmi输出，需要对设备树进行相应的修改，

1、修改设备树文件imx6qdl-phytec-mira-peb-av-02.dtsi，将默认mxcfb1的lcd设备注释，

Code Block
languagebash
themeMidnight
/*
       mxcfb1: fb@0 {
               disp_dev = "lcd";
               interface_pix_fmt = "RGB24";
               default_bpp = <16>;
               int_clk = <0>;
               late_init = <0>;
               status = "okay";
       };
*/

2、修改设备树文件imx6qdl-phytec-mira.dtsi

Code Block
languagebash
themeMidnight
&hdmi_core {
        ipu_id = <0>;
        disp_id = <0>;

        status = "okay";                                        					#status改为okay
};

&hdmi_video {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_hdmi_ddc>;

        fsl,phy_reg_vlev = <0x294>; /* TODO check */
        fsl,phy_reg_cksymtx = <0x800d>;
        fsl,hdcp;

        status = "okay";															#status改为okay
};

&hdmi_audio {
        status = "okay";															#status改为okay
};

&hdmi_cec {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_hdmi_cec>;

        status = "okay";															#status改为okay
};
Code Block
languagebash
themeMidnight
 mxcfb1: fb@0 {
         reg = <0 0>;
         compatible = "fsl,mxc_sdc_fb";
         disp_dev = "hdmi";
         interface_pix_fmt = "RGB24";
         default_bpp = <16>;
         int_clk = <0>;
         late_init = <0>;
		 status = "okay";
};
