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
[cpp] view plain copy
- #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
[cpp] view plain copy
- UINT32 OV13850_MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);
在kdSensorList数组中增加OV13850配置
[cpp] view plain copy
- 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。
[cpp] view plain copy
- 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)))

- msleep(1);
- printk("OV13850 PWN RST\\n");
- //...
Lens:
- 在mediatek\\custom\\common\\kernel\\lens\\目录下参照ov12830af,增加ov13850af 目录和驱动源码OV13850AF.c。
-
mediatek\\custom\\common\\kernel\\lens\\inc\\目录下参照ov12830af,增加ov13850af目录和OV13850AF.h头文件
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。
[cpp] view plain copy
- 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。
[cpp] view plain copy
- #if defined(OV13850AF)
- extern PFUNC_GETLENSDEFAULT pOV13850AF_getDefaultData;
- #endif
MSDK_LENS_INIT_FUNCTION_STRUCT LensList[MAX_NUM_OF_SUPPORT_LENS] =
[cpp] view plain copy
- ...
- #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。
[cpp] view plain copy
- #define OV13850AF_LENS_ID 0x0008
3、修改ProductConfig.mk
[plain] view plain copy
- 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。
