一、驱动源码包结构
拿到的驱动源码包解压后得到hal和kernel两个目录文件，源码目录结构如下所示

二、ov13850驱动移植记录
1、kernel
Sensor：
- 在mediatek\custom\common\kernel\imgsensor\目录下增加ov13850_mipi_raw文件夹，把驱动源码kernel目录中所有文件copy进来。
- 修改mediatek\custom\common\kernel\imgsensor\inc\kd_imgsensor.h文件，增加ov13850 SENSOR_ID和SENSOR_DRVNAME定义
- #define OV13850_SENSOR_ID 0xD850
- #define SENSOR_DRVNAME_OV13850_MIPI_RAW "ov13850mipiraw"
- 修改mediatek\custom\common\kernel\imgsensor\src\kd_sensorlist.h
增加OV13850_MIPI_RAW_SensorInit函数声明
- UINT32 OV13850_MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);
在kdSensorList数组中增加OV13850配置
- ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] =
- {
- ...
- #if defined(OV13850_MIPI_RAW)
- {OV13850_SENSOR_ID, SENSOR_DRVNAME_OV13850_MIPI_RAW, OV13850_MIPI_RAW_SensorInit},
- #endif
- ...
- }
- 在mediatek\custom\wind92_wet_tdd\kernel\camera\camera\kd_camera_hw.c里，增加对OV13850的供电配置，参考OV12830和datasheet。由于OV12830和OV13850供电配置一样，所以copy12830，更改下名字即可。
- int kdCISModulePowerOn(CAMERA_DUAL_CAMERA_SENSOR_ENUM SensorIdx, char *currSensorName, BOOL On, char* mode_name)
- {
- //...
- else if (currSensorName && (0 == strcmp(SENSOR_DRVNAME_OV13850_MIPI_RAW,currSensorName)))
- {

Lens：
2、HAL
Sensor：
- 在mediatek\custom\mt6592\hal\imgsensor\目录下增加ov13850_mipi_raw文件夹，将OV13850驱动源码包中的hal下文件，copy到该文件夹下。
- 修改mediatek\custom\common\hal\imgsensor\src\sensorlist.cpp增加OV13850的SensorList描述项。
- MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] =
- {
- ...
- #if defined(OV13850_MIPI_RAW)
- RAW_INFO(OV13850_SENSOR_ID, SENSOR_DRVNAME_OV13850_MIPI_RAW,NULL),
- #endif
- ...
- }
Lens：
- 在mediatek\custom\common\hal\lens\下，增加ov13850af目录，参照ov12830增加lens_para_OV13850AF.cpp
- 修改mediatek\custom\out\wind92_wet_tdd\hal\lens\src\Lenslist.cpp在LensList数组项里增加OV13850AF描述项。
- #if defined(OV13850AF)
- extern PFUNC_GETLENSDEFAULT pOV13850AF_getDefaultData;
- #endif
MSDK_LENS_INIT_FUNCTION_STRUCT LensList[MAX_NUM_OF_SUPPORT_LENS] =
- {
- ...
- #if defined(OV13850AF)
- {OV13850_SENSOR_ID, OV13850AF_LENS_ID, "OV13850AF", pOV13850AF_getDefaultData},
- #endif
- ...
- }
- 修改camera_custom_lens.h，增加OV13850_LENS_ID，这里根据序号累加。
- #define OV13850AF_LENS_ID 0x0008
3、修改ProductConfig.mk
- CUSTOM_HAL_IMGSENSOR= ov13850_mipi_raw ov5648_mipi_raw
- CUSTOM_HAL_LENS= ov13850af dummy_lens
- CUSTOM_HAL_MAIN_IMGSENSOR= ov13850_mipi_raw
- CUSTOM_HAL_MAIN_LENS= ov13850af
- CUSTOM_KERNEL_IMGSENSOR= ov13850_mipi_raw ov5648_mipi_raw
- CUSTOM_KERNEL_LENS= ov13850af dummy_lens
- CUSTOM_KERNEL_MAIN_IMGSENSOR= ov13850_mipi_raw
- CUSTOM_KERNEL_MAIN_LENS= ov13850af
4、最后要修改init.rc 更改OV13850AF设备文件的权限，否则在open的时候会失败。
