[RK3288][Android6.0] 调试笔记 --- RT5640的ctl name列表

Platform: Rockchip
OS: Android 6.0
Kernel: 3.10.92
Codec: RT5640

在查看录音通路的ctl config列表时发现有找不到的ctrl name, 例如：

const struct config_control rt3261_main_mic_capture_controls[] = {    {        .ctl_name = "RxDC Mux",        .str_val = "Mono_ADC",    },    ....};

“RxDC Mux”这个name在驱动中并没有找到，因此它是无效的。
其实这些ctl name可以通过tinymix来确定是否存在，以下是RT5640所有支持的ctl.

生成此ctl list的驱动文件是rt3261.c，ctl name对应的value也可以在此驱动文件中查看。
例如名字为”IN1 Mode Control”的ctl name支持的值是：

static const char *rt3261_input_mode[] = {    "Single ended", "Differential"};
