驱动中的大多数数据都是需要供应商提供参考的，
需要注意的是sensor的不同输出模式对应不同的寄存器设置，根据这个会有RES0_REG_ARRAY，RES1_REG_ARRAY等，一般对应不同的分辨率输出，对应的需要在res_settings_array，out_info_array等中添加多个res与之对应，
另外需要注意的是：这里不同的res输出需要对应tunning的分别调试，所以在vendor/qcom/propriety/mm-camera/mm-camera2/media-controll/module/sensor/config/XXXX_chromatix.xml中添加对应模式（这里对应对tunning参数的调用）。

某些参数具体意义还不是很清楚，有待进一步补充
