1. 配置前摄CAM_RST1,SCL2,SDL2,CAM_PDN1,CMMCLK1参数


2. 配置camera(.dts文件)各个参数


3. camera 前摄移植

(1) 添加驱动文件

将camera驱动文件夹ov5648_mipi_raw添加到以下目录中

kernel-4.4\drivers\misc\mediatek\imgsensor\src\mt6771\ov5648sub_mipi_raw

vendor\mediatek\proprietary\custom\mt6771\hal\senindepfeature\ov5648sub_mipi_raw
vendor\mediatek\proprietary\custom\mt6771\hal\imgsensor\ver1\ov5648sub_mipi_raw
vendor\mediatek\proprietary\custom\mt6771\hal\imgsensor_metadata\ov5648sub_mipi_raw

kernel-4.4\drivers\misc\mediatek\imgsensor\src\common\v1_1\ov5648sub_mipi_raw

(2) 修改配置文件

(2.1) device\mediateksample\tb8788p1_64_bsp\ ProjectConfig.mk

作为main camera（主摄）时在CUSTOM_HAL_MAIN_IMGSENSOR ，CUSTOM_KERNEL_MAIN_IMGSENSOR 添加。若为sub camera（副摄） ，则在CUSTOM_HAL_SUB_IMGSENSOR ，CUSTOM_KERNEL_SUB_IMGSENSOR 后添加。CUSTOM_HAL_IMGSENSOR,CUSTOM_KERNEL_IMGSENSOR 主副摄都要添加。

CUSTOM_HAL_IMGSENSOR = ov5648_mipi_raw ov5648sub_mipi_raw

CUSTOM_HAL_MAIN_IMGSENSOR = ov5648_mipi_raw

CUSTOM_HAL_SUB_IMGSENSOR = ov5648sub_mipi_raw

CUSTOM_KERNEL_IMGSENSOR = ov5648_mipi_raw ov5648sub_mipi_raw

CUSTOM_KERNEL_MAIN_IMGSENSOR = ov5648_mipi_raw

CUSTOM_KERNEL_SUB_IMGSENSOR = ov5648sub_mipi_raw

(2.2) kernel-4.4\arch\arm64\configs\ tb8788p1_64_bsp_debug_defconfig和tb8788p1_64_bsp_defconfig

在kernel中添加的文件夹名，注意要与ProjectConfig.mk的CUSTOM_HAL_IMGSENSOR，CUSTOM_KERNEL_IMGSENSOR 一致，否则编译会报错，主副摄都要添加。

CONFIG_CUSTOM_KERNEL_IMGSENSOR="ov5648_mipi_raw ov5648sub_mipi_raw"

(2.3) device\mediatek\common\kernel-headers\ kd_imgsensor.h   /*hal 调用*/

kernel-4.4\drivers\misc\mediatek\imgsensor\ inc\kd_imgsensor.h   /*kernel 调用*/

定义ov5648sub_mipi_raw 的sensorid_ID和设备名

#define OV5648SUBMIPI_SENSOR_ID                0x5649

#define SENSOR_DRVNAME_OV5648SUB_MIPI_RAW      "ov5648sub_mipi_raw"

(2.4) kernel-4.4\drivers\misc\mediatek\ imgsensor\src\mt6771\camera_project\tb8788p1_64_bsp\ camera_hw\ imgsensor_cfg_table.c

在sensor_power_sequence[]添加上电电压和时序设置

#if defined(OV5648SUB_MIPI_RAW)        

{               

SENSOR_DRVNAME_OV5648_MIPI_RAW,               

           {                        

                {SensorMCLK, Vol_High, 0},                        

                {PDN, Vol_Low, 0},                        

                {PDN, Vol_Low, 0},                        

                {DOVDD, Vol_1800, 0},                        

                {AVDD, Vol_2800, 1},                        

                {DVDD, Vol_1500, 1},                        

                {AFVDD, Vol_2800, 5},                        

                {PDN, Vol_High, 1},                        

                {RST, Vol_High, 10}               

        },        

   },

#endif

(2.5) kernel-4.4\drivers\misc\mediatek\imgsensor\ src\common\v1\imgsensor_sensor_list.c

kernel-4.4\drivers\misc\mediatek\imgsensor\ src\common\v1_1\imgsensor_sensor_list.c

在imgsensor_sensor_list.c添加新的传感器驱动程序

#if defined(OV5648_MIPI_RAW)

{OV5648SUBMIPI_SENSOR_ID,SENSOR_DRVNAME_OV5648SUB_MIPI_RAW, OV5648SUBMIPISensorInit},

#endif

kernel-4.4\drivers\misc\mediatek\imgsensor\ src\common\v1_1\imgsensor_sensor_list.h

在imgsensor_sensor_list.h添加新的传感器驱动程序

UINT32 OV5648SUBMIPISensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

(2.7) vendor\mediatek\proprietary\custom\mt6771\ hal\imgsensor_src\sensorlist.cpp

在sensorlist.cpp中添加新的传感器驱动程序，并且和imgsensor_sensor_list.c文件中列表中添加的位置一致

#if defined(OV5648SUB_MIPI_RAW)

RAW_INFO_M(OV5648SUBMIPI_SENSOR_ID,DEFAULT_MODULE_INDEX,DEFAULT_MODULE_ID,SENSOR_DRVNAME_O        V5648SUB_MIPI_RAW, NULL),

#endif

驱动马达跟ov5648sub_mipi_raw用同个驱动代码文件，未能实现效果，驱动马达没有跑起来，在找原因
