一、驅動原始碼包結構
拿到的驅動原始碼包解壓後得到hal和kernel兩個目錄檔案，原始碼目錄結構如下所示

二、ov13850驅動移植記錄
1、kernelSensor：
- 在mediatek\custom\common\kernel\imgsensor\目錄下增加ov13850_mipi_raw資料夾，把驅動原始碼kernel目錄中所有檔案copy進來。
- 修改mediatek\custom\common\kernel\imgsensor\inc\kd_imgsensor.h檔案，增加ov13850 SENSOR_ID和SENSOR_DRVNAME定義
- #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函式宣告
- UINT32 OV13850_MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);
在kdSensorList陣列中增加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裡，增加對OV13850的供電配置，參考OV12830和datasheet。由於OV12830和OV13850供電配置一樣，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)
- {
- //...
- elseif (currSensorName && (0 == strcmp(SENSOR_DRVNAME_OV13850_MIPI_RAW,currSensorName)))

Lens：
- 在mediatek\custom\common\kernel\lens\目錄下參照ov12830af，增加ov13850af 目錄和驅動原始碼OV13850AF.c。
-
mediatek\custom\common\kernel\lens\inc\目錄下參照ov12830af，增加ov13850af目錄和OV13850AF.h標頭檔案
Sensor：
- 在mediatek\custom\mt6592\hal\imgsensor\目錄下增加ov13850_mipi_raw資料夾，將OV13850驅動原始碼包中的hal下檔案，copy到該資料夾下。
- 修改mediatek\custom\common\hal\imgsensor\src\sensorlist.cpp增加OV13850的SensorList描述項。
- 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目錄，參照ov12830增加lens_para_OV13850AF.cpp
- 修改mediatek\custom\out\wind92_wet_tdd\hal\lens\src\Lenslist.cpp在LensList陣列項裡增加OV13850AF描述項。
MSDK_LENS_INIT_FUNCTION_STRUCT LensList[MAX_NUM_OF_SUPPORT_LENS] =
- #if defined(OV13850AF)
- extern PFUNC_GETLENSDEFAULT pOV13850AF_getDefaultData;
- #endif
- {
- ...
- #if defined(OV13850AF)
- {OV13850_SENSOR_ID, OV13850AF_LENS_ID, "OV13850AF", pOV13850AF_getDefaultData},
- #endif
- ...
- }
- 修改camera_custom_lens.h，增加OV13850_LENS_ID，這裡根據序號累加。
- #define OV13850AF_LENS_ID 0x0008
3、修改ProductConfig.mk
4、最後要修改init.rc 更改OV13850AF裝置檔案的許可權，否則在open的時候會失敗。
