手机摄像头驱动移植办法

admin

一、驱动源码包结构

OV13850摄像头在MTK6592平台，驱动移植方法，拿到的驱动源码包解压后得到hal和kernel两个目录文件，源码目录结构如下所示：
13850-6592-driver-10-28.7z
  C6 n  E+ n3 D) r  O|--hal
( o% {) {4 f! `  ^; B) _|  |--camera_AE_PLineTable_ov13850mipiraw.h

二、ov13850驱动移植记录
1、kernel

Sensor：

• 在mediatek\custom\common\kernel\imgsensor\目录下增加ov13850_mipi_raw文件夹，把驱动源码kernel目录中所有文件copy进来。
• 修改mediatek\custom\common\kernel\imgsensor\inc\kd_imgsensor.h文件，增加ov13850 SENSOR_ID和SENSOR_DRVNAME定义
  

6 W2 e! G; p7 i8 y: d
: A( d  t% m: u# C0 }" l9 f  S2 W+ B. E

• #define OV13850_SENSOR_ID             0xD850  
• #define SENSOR_DRVNAME_OV13850_MIPI_RAW   "ov13850mipiraw"  
  - A2 ?; l/ |! ^4 V1 w: o

5 D4 D, {: L2 o! c1 v: x# _" [

• 修改mediatek\custom\common\kernel\imgsensor\src\kd_sensorlist.h
  ! O5 @$ M# s1 Z
  5 r2 Z3 U* S& f1 S% m( E& A: @9 m

% x/ S% A( [* d) }

增加OV13850_MIPI_RAW_SensorInit函数声明
& u, G6 |) L) y2 r) h

• UINT32 OV13850_MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);  
  

' X3 V; W! v/ y# g, p5 s

在kdSensorList数组中增加OV13850配置

• ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] =  
• {  
• ...  
• #if defined(OV13850_MIPI_RAW)  
•     {OV13850_SENSOR_ID, SENSOR_DRVNAME_OV13850_MIPI_RAW, OV13850_MIPI_RAW_SensorInit},   
• #endif  
• ...  
• }  
  

+ y9 D: D2 ]8 z' `

• 在mediatek\custom\wind92_wet_tdd\kernel\camera\camera\kd_camera_hw.c里，增加对OV13850的供电配置，参考OV12830和datasheet。由于OV12830和OV13850供电配置一样，所以copy12830，更改下名字即可。

2、HAL

Sensor：

• 在mediatek\custom\mt6592\hal\imgsensor\目录下增加ov13850_mipi_raw文件夹，将OV13850驱动源码包中的hal下文件，copy到该文件夹下。
• 修改mediatek\custom\common\hal\imgsensor\src\sensorlist.cpp增加OV13850的SensorList描述项。

3、修改ProductConfig.mk

0 V8 ]# w/ L' P% b0 L

• CUSTOM_HAL_IMGSENSOR= ov13850_mipi_raw ov5648_mipi_raw  
• CUSTOM_HAL_LENS= ov13850af  dummy_lens  
• CUSTOM_HAL_MAIN_IMGSENSOR= ov13850_mipi_raw  
• CUSTOM_HAL_MAIN_LENS= ov13850af  
• CUSTOM_KERNEL_IMGSENSOR= ov13850_mipi_raw ov5648_mipi_raw  
• CUSTOM_KERNEL_LENS= ov13850af dummy_lens  
• CUSTOM_KERNEL_MAIN_IMGSENSOR= ov13850_mipi_raw  
• CUSTOM_KERNEL_MAIN_LENS= ov13850af  
  ! `: R/ e( C( F

4、最后要修改init.rc 更改OV13850AF设备文件的权限，否则在open的时候会失败。
