摄像头驱动

-----------------------camera---------------------------------
1、调camera sensor
   增加一个image sensor:
   1)、增加kernel和hal的两个imgsensor的子目录
        mediatek\custom\common\kernel\imgsensor\xxx_yuv
        mediatek\custom\common\hal\imgsensor\xxx_yuv (定义好函数xxx_YUV_SensorInit(){.xxx结构体..})
   2) 在mediatek\custom\common\kernel\imgsensor\inc\Kd_imgsensor.h增加
            #define XXX_SENSOR_ID     0x00A6 
            #define SENSOR_DRVNAME_XXX_YUV     "xxxyuv" 
   3) 在mediatek\custom\common\kernel\imgsensor\src\Kd_sensorlist.h的
       数组中ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] ={...按顺序加上
        #if defined(XXX_YUV)//
    {XXX_SENSOR_ID, SENSOR_DRVNAME_XXX_YUV, XXX_YUV_SensorInit}, 
#endif


   4) 在mediatek\custom\common\hal\imgsensor\src\Sensorlist.cpp文件的
       数组中MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] ={...按顺序加上(与上面的kdSensorList[]要一一对应上)
#if defined(XXX_YUV)
   YUV_INFO(XXX_SENSOR_ID, SENSOR_DRVNAME_XXX_YUV, NULL), 
#endif
   //若要在SW实现多颗sensor的兼容，在配置kdSensorList和SensorList两个数组时，需要保证其信息一致。即这两个sensor list中sensor index的顺序要一致，
若不一致，则会导致错call到其它sensor的init函数，读错feature table（读了其它sensor的配置），最终产生问题。


2、camera的电源控制(kd_camera_hw.c 与功能机(MT62xx)的camera_hw.c是一样的)
   int kdCISModulePowerOn(CAMERA_DUAL_CAMERA_SENSOR_ENUM SensorIdx, char *currSensorName, BOOL On, char* mode_name)
   {
      大部份摄像头都是  拉低工作=GPIO_OUT_ZERO，拉高不工作(powerDown)=GPIO_OUT_ONE
      #define IDX_PS_ON   2   //可以认为,表示工作(V LOW)
      #define IDX_PS_OFF  3   //可以认为,表示不工作(V HIGH)
   }
   各种电压值可调.
    if ((powerId == MT65XX_POWER_LDO_VSIM)
    ||(powerId == MT65XX_POWER_LDO_VSIM2)
    ||(powerId == MT65XX_POWER_LDO_VCAMD)
    ||(powerId == MT65XX_POWER_LDO_VCAM_IO)
    ||(powerId == MT65XX_POWER_LDO_VCAM_AF)
    ||(powerId == MT65XX_POWER_LDO_VMC)
    ||(powerId == MT65XX_POWER_LDO_VMCH)
    ||(powerId == MT65XX_POWER_LDO_VGP)
    ||(powerId == MT65XX_POWER_LDO_VGP2)
    ||(powerId == MT65XX_POWER_LDO_VIBR)
    ||(powerId == MT65XX_POWER_LDO_VA1)
    ||(powerId == MT65XX_POWER_LDO_VA2)
    ||(powerId == MT65XX_POWER_LDO_VCAMA)    




3、摄像头PIN连接
AVDD -- 2.8V
DVDD -- 1.8V 
DOVDD --IO电压 1.8V
对于低像素的(0.3M),基本上使用的都是1.8V，所以一般DVDD和DOVDD是并联1.8V。
对于高像素的(5M),则DVDD会要求要1.3V，则需要单独供电.
所以，DVDD要看是供了什么电压.

首先说说2点：
1、Camera 的成像原理:

景物通过镜头(LENS)生成的光学图像投射到图像传感器(Sensor)表面上,然后转为模拟的电信号,经过 A/D(模数转换)转换后变为数字图像信号,再送到数字信号处理芯片(DSP)中加工处理,再通过 IO 接口传输到 CPU 中处理,通过 LCD 就可以看到图像了。...
