一、使用場景

我們是通過rk主控的hdmi接口播放音視頻給到ite68051芯片解析出8聲道數據，分別通過4路i2s的數據腳給給到fpga去解析

調試步驟：

1.根據相關手冊配置hdmi輸出，hdmi聲卡注冊，如下:

hdmi0_sound: hdmi0-sound {
        status = "disabled";
        compatible = "rockchip,hdmi";
        rockchip,mclk-fs = <128>;
        rockchip,card-name = "rockchip-hdmi0";
        rockchip,cpu = <&i2s5_8ch>;
        rockchip,codec = <&hdmi0>;
        rockchip,jack-det;
    };&hdmi0_sound {
    status = "okay";
};&i2s5_8ch {
    status = "okay";
};hdmi0: hdmi@fde80000 {
        compatible = "rockchip,rk3588-dw-hdmi";
        reg = <0x0 0xfde80000 0x
