这里是以mt6739+kernel4.4平台添加gc5025，fm50af为例

1.device/mediatek/common/kernel-headers/kd_imgsensor.h添加摄像头ID与名称

#define GC5025_SENSOR_ID				0x5025
#define SENSOR_DRVNAME_GC5025_MIPI_RAW			"gc5025_mipi_raw"

2.在项目配置文件device/mediateksample/k39tv1_bsp_1g/ProjectConfig.mk修改camera信息

CUSTOM_HAL_IMGSENSOR = gc5025_mipi_raw
CUSTOM_HAL_LENS = fm50af dummy_lens

CUSTOM_HAL_MAIN_BACKUP_LENS = 
CUSTOM_HAL_MAIN_IMGSENSOR = gc5025_mipi_raw
CUSTOM_HAL_MAIN_LENS = fm50af 
副摄像头为空：
CUSTOM_HAL_SUB_BACKUP_LENS = 
CUSTOM_HAL_SUB_IMGSENSOR = 
CUSTOM_HAL_SUB_LENS = 

CUSTOM_KERNEL_IMGSENSOR = gc5025_mipi_raw

CUSTOM_KERNEL_LENS = fm50af dummy_lens

CUSTOM_KERNEL_MAIN_BACKUP_LENS = 
CUSTOM_KERNEL_MAIN_IMGSENSOR = gc5025_mipi_raw
CUSTOM_KERNEL_MAIN_LENS = fm50af
副摄像头为空：
CUSTOM_KERNEL_SUB_BACKUP_LENS = 
CUSTOM_KERNEL_SUB_IMGSENSOR = 
CUSTOM_KERNEL_SUB_LENS = 

3.kernel-4.4/arch/arm/configs/k39tv1_bsp_1g_debug_defconfig配置文件

CONFIG_CUSTOM_KERNEL_IMGSENSOR="gc5025_mipi_raw"

4.kernel-4.4/arch/arm/configs/k39tv1_bsp_1g_defconfig配置文件

CONFIG_CUSTOM_KERNEL_IMGSENSOR="gc5025_mipi_raw"

5.kernel-4.4/drivers/misc/mediatek/imgsensor/inc/kd_imgsensor.h

#define GC5025_SENSOR_ID				0x5025
#define SENSOR_DRVNAME_GC5025_MIPI_RAW			"gc5025_mipi_raw"

6.kernel-4.4/drivers/misc/mediatek/imgsensor/src/common/v1/目录添加gc5025_mipi_raw驱动文件

7.kernel-4.4/drivers/misc/mediatek/imgsensor/src/common/v1/imgsensor_sensor_list.c添加camera gc5025

+#if defined(GC5025_MIPI_RAW)
+    {GC5025_SENSOR_ID, SENSOR_DRVNAME_GC5025_MIPI_RAW, GC5025MIPI_RAW_SensorInit},

8.kernel-4.4/drivers/misc/mediatek/imgsensor/src/common/v1/imgsensor_sensor_list.h

UINT32 GC5025MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

9.kernel-4.4/drivers/misc/mediatek/imgsensor/src/mt6739/camera_hw/imgsensor_cfg_table.c添加上下电信息

+#if defined(GC5025_MIPI_RAW)
+	{
+		SENSOR_DRVNAME_GC5025_MIPI_RAW,
+		{
+			{SensorMCLK, Vol_High, 0},
+			{PDN, Vol_Low, 1},
+			{RST, Vol_Low, 10},
+			{DOVDD, Vol_1800, 5},
+			{DVDD, Vol_1200, 5},
+			{AVDD, Vol_2800, 5},
+			{AFVDD, Vol_2800, 5},
+			{PDN, Vol_High, 5},
+			{RST, Vol_High, 5}
+		},
+	},
+#endif

10.vendor/mediatek/proprietary/custom/mt6739/hal/imgsensor/目录添加厂家提供的文件gc5025_mipi_raw

11.vendor/mediatek/proprietary/custom/mt6739/hal/imgsensor_src/sensorlist.cpp添加信息

+#if defined(GC5025_MIPI_RAW)
+    RAW_INFO(GC5025_SENSOR_ID, SENSOR_DRVNAME_GC5025_MIPI_RAW, NULL),

11.vendor/mediatek/proprietary/custom/mt6739/hal/lens/src/lenslist.cpp

 #if defined(FM50AF)
+	{GC5025_SENSOR_ID, FM50AF_LENS_ID, "FM50AF", pFM50AF_getDefaultData},
 #endif

12.vendor/mediatek/proprietary/custom/mt6739/hal/sendepfeature/添加gc5025_mipi_raw文件夹放置效果文件

           config.ftbl.gc5025mipi_raw.h

13.添加af驱动位置

  kernel-4.4\drivers\misc\mediatek\lens\main\common

   vendor\mediatek\proprietary\custom\mt6739\hal\lens

 

另外，还要修改dws文件的i2c地址以及一些ldo电源的输出配置，dts上的camera是配置好的，不需要修改
