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_rawvendor\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_rawkernel-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_rawCUSTOM_HAL_MAIN_IMGSENSOR = ov5648_mipi_rawCUSTOM_HAL_SUB_IMGSENSOR = ov5648sub_mipi_rawCUSTOM_KERNEL_IMGSENSOR = ov5648_mipi_raw ov5648sub_mipi_rawCUSTOM_KERNEL_MAIN_IMGSENSOR = ov5648_mipi_rawCUSTOM_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.ckernel-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
(2.6) kernel-4.4\drivers\misc\mediatek\imgsensor\ src\common\v1\imgsensor_sensor_list.hkernel-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
