VS-RK3399在android下面把声音放到最大时候，播放器自动退出问题
VS-RK3399 在android下面把声音放到最大时候，播放器自动退出问题。使用系统自带的Video.apk播放，当声音放到最大时候，播放视频过一会后自动退出，影响ADC采样，干扰了物理键，返回一个back键出来，刚好Video.apk有处理返回键的相应，导致播放时候退出。
修改方法：
\kernel\arch\arm64\boot\dts\rockchip\rk3399-android.dtsi
rk_key: rockchip-key {
           compatible = "rockchip,key";
           status = "okay";

           io-channels =<& saradc 1>;

           vol-up-key {
                 linux,code =< 115>;
                 label = "volume up";
                 rockchip,adc_value =< 1>;
           };

           vol-down-key {
                 linux,code =< 114>;
                 label = "volume down";
                 rockchip,adc_value =< 170>;
           };

           power-key {
                 gpios =<& gpio0 5 GPIO_ACTIVE_LOW>;
                 linux,code =< 116>;
                 label = "power";
                 gpio-key,wakeup;
           };
#if 0
           menu-key {
                 linux,code =< 59>;
                 label = "menu";
                 rockchip,adc_value =< 746>;
           };

           home-key {
                 linux,code =< 102>;
                 label = "home";
                 rockchip,adc_value =< 355>;
           };

           back-key {
                 linux,code =< 158>;
                 label = "back";
                 rockchip,adc_value =< 560>;
           };

           camera-key {
                 linux,code =< 212>;
                 label = "camera";
                 rockchip,adc_value =< 450>;
           };
#endif

       };

按上面操作，把back键去掉
