mtk camera移植

mtk camera 移植步骤:

1, Kernel层驱动代码文件添加

/mediatek/custom/doov92_wet_tdd/kernel/imgsensor/下添加imx179_mipi_raw_

2lane/ 目录如下:

imx179_mipi_raw_2lane

- imx179mipiraw_Camera_Sensor_para_2lane.h

- imx179mipiraw_CameraCustomized_2lane.h

- imx179mipiraw_Sensor_2lane.c

- imx179mipiraw_Sensor_2lane.h

看了一下, 基本上所有的驱动文件都是这样的格式.

2, HAL层效果参数文件添加

/mediatek/custom/mt6592/hal/imgsensor/下添加imx179_mipi_raw_2lane目录,该目录list如下:

imx179_mipi_raw_2lane

- camera_AE_PLineTable_imx179raw_2lane.h

- camera_calibration_cam_cal_2lane.cpp

- camera_flicker_para_imx179raw_2lane.cpp

- camera_info_imx179raw_2lane.h

- camera_isp_lsc_imx179raw_2lane.h

- camera_isp_pca_imx179raw_2lane.h

- camera_isp_regs_imx179raw_2lane.h

- camera_tsf_data_imx179raw_2lane.h

- camera_tsf_para_imx179raw_2lane.h

- camera_tuning_para_imx179raw_2lane.cpp

- config.ftbl.imx179_mipi_raw_2lane.h

根据具体的sensor, 文件会有所增减.

3, 驱动结构添加

./mediatek/custom/common/kernel/imgsensor/src/kd_sensorlist.H:

1)UINT32 IMX179_MIPI_RAW_2lane_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

2) ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] =

{

#if defined(IMX179_MIPI_RAW_2LANE)//addimx179sensor(front), jintao_20140114_camera_front +++

{IMX179_SENSOR_2LANE_ID, SENSOR_DRVNAME_IMX179_MIPI_RAW, IMX179_MIPI_RAW_2lane_SensorInit},

#endif

......

}

4, 定义ID和drv name

./mediatek/custom/common/kernel/imgsensor/inc/kd_imgsensor.h:

#define IMX179_SENSOR_2LANE_ID 0x0179

#define SENSOR_DRVNAME_IMX179_MIPI_RAW "imx179mipiraw_2lane"

5, HAL层ID与drv name的衔接

./mediatek/custom/common/hal/imgsensor/src/sensorlist.cpp

MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] =

{

#if defined(IMX179_MIPI_RAW_2LANE)//add imx179 sensor(front), jintao_20140114_camera_front +++

RAW_INFO(IMX179_SENSOR_2LANE_ID, SENSOR_DRVNAME_IMX179_MIPI_RAW, NULL),

#endif

......

}

6, Camera Sensor宏配置

/mediatek/config/doov92_wet_tdd/ProjectConfig.mk ==配置

CUSTOM_HAL_IMGSENSOR=imx135_mipi_raw imx179_mipi_raw_2lane

CUSTOM_HAL_SUB_IMGSENSOR=imx179_mipi_raw_2lane

CUSTOM_KERNEL_IMGSENSOR=imx135_mipi_raw imx179_mipi_raw_2lane

CUSTOM_KERNEL_SUB_IMGSENSOR=imx179_mipi_raw_2lane

7,时序配置

./mediatek/custom/doov92_wet_tdd/kernel/camera/camera/kd_camera_hw.c

else if (currSensorName && (0 == strcmp(currSensorName,"imx179mipiraw_2lane")))

分别配置上电/下电. 原理图上的PIN脚收集如下.

Main Sensor 控制脚:

CMRST_MAIN CMPDN_MAIN

VCAM_AF AF_EN

VCAMD VCAMA

VCAMIO

SCL SDA

CMMCLK

MIPI-RDP0 MIPI-RDN0

MIPI-RDP1 MIPI-RDN1

MIPI-RDP2 MIPI-RDN2

MIPI-RDP3 MIPI-RDN3

MIPI-RCP MIPI-RCN

F-LED+

F-LED1-

F-LED2-

8,Camera预览/拍照储存照片的方向改变

./mediatek/custom/doov92_wet_tdd/hal/imgsensor/src/cfg_setting_imgsensor.cpp //改的是这个

SensorOrientation_T const&

getSensorOrientation()

{

static SensorOrientation_T const inst = {

u4Degree_0 : 270, // main sensor in degree (0, 90, 180, 270), 后摄的方向配置.

u4Degree_1 : 270, // sub sensor in degree (0, 90, 180, 270), 前摄的方向配置.

u4Degree_2 : 90, // main2 sensor in degree (0, 90, 180, 270), 主设2的方向配置.

};

return inst;

}
