mtk camera 移植步驟:

1, Kernel層驅(qū)動代碼文件添加

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

2lane/??目錄如下:

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,?基本上所有的驅(qū)動文件都是這樣的格式.

2, HAL層效果參數(shù)文件添加

/mediatek/custom/mt6592/hal/imgsensor/下添加imx179_mipi_raw_2lane目錄,該目錄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

根據(jù)具體的sensor,?文件會有所增減.

3,?驅(qū)動結(jié)構(gòu)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,?定義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層ID與drv name的銜接

./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,時序配置

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

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

分別配置上電/下電.??????????????原理圖上的PIN腳收集如下.

Main Sensor?控制腳:

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預(yù)覽/拍照儲存照片的方向改變

./mediatek/custom/doov92_wet_tdd/hal/imgsensor/src/cfg_setting_imgsensor.cpp //改的是這個

SensorOrientation_T const&

getSensorOrientation()

{

??? static SensorOrientation_T const inst = {

??????? u4Degree_0? : 270,???//??main sensor in degree (0, 90, 180, 270),?后攝的方向配置.

??????? u4Degree_1? : 270,????//??sub? sensor in degree (0, 90, 180, 270),?前攝的方向配置.

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

??? };

??? return inst;

}
