MT6789 kernel-5.10 

6789代码跟6761、62、65不一样

如何点亮一颗摄像头

例 main：ov64b40_mipi_raw

摄像头驱动路径：

1.驱动 放入驱动文件

路径：alps\kernel-5.10\drivers\misc\mediatek\imgsensor\src\common\v1_1\ov64b40_mipi_raw

1.1Makefile 

路径：alps\kernel-5.10\drivers\misc\mediatek\imgsensor\src\common\v1_1\Makefile

#endif

4.imgsensor_sensor_list.h

路径：alps\kernel-5.10\drivers\misc\mediatek\imgsensor\src\common\v1_1\imgsensor_sensor_list.h

UINT32 OV64B40MIPISensorInit(struct SENSOR_FUNCTION_STRUCT **pfFunc);

5. sensorlist.cpp

alps\vendor\mediatek\proprietary\custom\common\hal\imgsensor_src\sensorlist.cpp

#if defined(OV64B40_MIPI_RAW)

    RAW_INFO_M(OV64B40_SENSOR_ID, DEFAULT_MODULE_INDEX, DEFAULT_MODULE_ID, SENSOR_DRVNAME_OV64B40_MIPI_RAW, NULL),

#endif

5.1第二个cpp  lenslist.cpp 这是对焦马达

路径：alps\vendor\mediatek\proprietary\custom\mt6789\hal\lens\src\lenslist.cpp

MSDK_LENS_INIT_FUNCTION_STRUCT LensList_main[MAX_NUM_OF_SUPPORT_LENS] =

{

{OV64B40_SENSOR_ID, DUMMY_MODULE_ID, DW9800WAF_LENS_ID, "DW9800WAF", NULL},

};

6.kd_imgsensor.h 定义id

alps\kernel-5.10\drivers\misc\mediatek\imgsensor\inc\kd_imgsensor.h

#define OV64B40_SENSOR_ID                       0x5664

#define SENSOR_DRVNAME_OV64B40_MIPI_RAW   "ov64b40_mipi_raw"

6.1另外一个kd_imgsensor.h（跟62 65一样）

路径：alps\device\mediatek\common\kernel-headers\kd_imgsensor.h

#define OV64B40_SENSOR_ID                       0x5664

#define SENSOR_DRVNAME_OV64B40_MIPI_RAW   "ov64b40_mipi_raw"

7. mtkcamvars.go(这个没看明白，就是有些的是十几个，有些二十几个，数目不一样)

路径：alps\vendor\mediatek\proprietary\scripts\soong\mtkcam\mtkcamvars.go

8、配置：五个

关键字 img

8.1 CameraConfig.mk

路径：alps\device\mediatek\mt6789\CameraConfig.mk

CUSTOM_HAL_IMGSENSOR = ov50c40_mipi_raw gc32e1_mipi_raw gc05a2_mipi_raw sc200cs_mipi_raw ov64b40_mipi_raw

CUSTOM_HAL_MAIN_IMGSENSOR = ov50c40_mipi_raw ov64b40_mipi_raw

CUSTOM_KERNEL_IMGSENSOR = ov50c40_mipi_raw gc32e1_mipi_raw gc05a2_mipi_raw sc200cs_mipi_raw ov64b40_mipi_raw

CUSTOM_KERNEL_MAIN_IMGSENSOR = ov50c40_mipi_raw ov64b40_mipi_raw

8.2device-camera.mk

路径：alps\device\mediatek\mt6789\device-camera.mk

CUSTOM_HAL_IMGSENSOR = ov50c40_mipi_raw gc32e1_mipi_raw gc05a2_mipi_raw sc200cs_mipi_raw ov64b40_mipi_raw

8.3ProjectConfig.mk

路径：alps\device\mediateksample\k6789v1_64

CUSTOM_HAL_IMGSENSOR = ov50c40_mipi_raw gc32e1_mipi_raw gc05a2_mipi_raw sc200cs_mipi_raw ov64b40_mipi_raw

CUSTOM_KERNEL_IMGSENSOR = ov50c40_mipi_raw gc32e1_mipi_raw gc05a2_mipi_raw sc200cs_mipi_raw ov64b40_mipi_raw

8.4ProjectConfig_def.mk

alps\device\mediateksample\ProjectConfig_def.mk

8.5mgk_64_k510_defconfig

alps\kernel-5.10\arch\arm64\configs\mgk_64_k510_defconfig

CONFIG_CUSTOM_KERNEL_IMGSENSOR="ov50c40_mipi_raw gc32e1_mipi_raw gc05a2_mipi_raw sc200cs_mipi_raw ov64b40_mipi_raw"

9.效果文件（这个摄像头效果文件跟62 65的不一样，很多文件，一般是copy，fae改效果的话只需要合几个文件）

alps\vendor\mediatek\proprietary\custom\mt6789\hal\imgsensor\ver1\ov64b40_mipi_raw

10.属性 跟62一样两个路径

属性1

alps\vendor\mediatek\proprietary\custom\mt6789\hal\imgsensor_metadata\ov64b40_mipi_raw

属性2

alps\vendor\mediatek\proprietary\custom\common\hal\imgsensor_metadata\sensor\ov64b40_mipi_raw

这也是属性，（以前8.1版本的）可以不用配这个，咱项目就没有配ov64b40的，已经整合到10.属性那里去了

alps\vendor\mediatek\proprietary\custom\mt6789\hal\sendepfeature\ov64b40_mipi_raw

已经整合到这了：alps\vendor\mediatek\proprietary\custom\mt6789\hal\imgsensor_metadata\ov64b40_mipi_raw

11.平台的翻转：（应该还有一个，像62的一样）

alps\vendor\mediatek\proprietary\custom\mt6789\hal\imgsensor_src\cfg_setting_imgsensor.cpp
