1、MTK_驱动总结文档　　G616驱动文档总结　　在/mediatek/custom下会有好多重名的文件，在不同的文件夹里，最终会编译哪个文件是根据目录的优先级来判断　　brighter89_evdo_jb2>mt6589>xxmon　　也就是说如果brighter89_evdo_jb2,mt6589,xxmon同时存在一文件，最终编译的会是brighter89_evdo_jb2目录下的文件　　也可以通过/mediatek/custom/out/开判断，此文件时最终编译的文件　　运行/mediatek/dct/。　　选择文件/mediatek/custom/brig

2、hter89_evdo_jb2/kernel/dct/dct/　　Edit，打开后可以修改GPIO的模式，上拉，下拉，输入，输出修改后点击“Save”和“GenCode”　　重新编译：./makeMtkbrighter89_evdo_jb2codegen./makeMtkbrighter89_evdo_jb2newpllkkernel./makeMtkbrighter89_evdo_jb2bootimage　　提交时替换bw/custom/project/g616/mediate/custom/brighter89_evdo_jb2/kernel/dct/dct　

3、　　　修改　　CUSTOM_LK_LCM=hx8389b_qhd_dsi_vdo　　BOOT_LOGO=qhd//根据屏的分辨率　　CUSTOM_KERNEL_LCM=hx8389b_qhd_dsi_vdoLCM_HEIGHT=960LCM_WIDTH=540　　/mediatek/custom/xxmon/kernel/lcm目录名与下hx8389b_qhd_dsi_vdo名字相同,目录下为驱动文件　　在/mediatek/custom/xxmon/kernel/lcm/mt65xx_lcm_下添加要添加的屏#ifdefined(HX8389B_QHD_DSI_

4、VDO)&hx8389b_qhd_dsi_vdo_lcm_drv,#endif　　　　下修改　　CUSTOM_HAL_IMGSENSOR=ov5648_mipi_rawhi257_yuv//前后cameraCUSTOM_HAL_MAIN_IMGSENSOR=ov5648_mipi_rawCUSTOM_HAL_SUB_IMGSENSOR=hi257_yuv　　CUSTOM_KERNEL_IMGSENSOR=ov5648_mipi_rawhi257_yuv//前后cameraCUSTOM_KERNEL_MAIN_IMGSENSOR=ov5648_mipi_rawCUS

5、TOM_KERNEL_SUB_IMGSENSOR=hi257_yuv　　驱动要添加的文件：　　/mediatek/custom/xxmon/kernel/imgsensor/ov5648_mipi_raw/mediatek/custom/xxmon/hal/imgsensor/ov5648_mipi_raw　　//hi257前camera同理　　/mediatek/custom/xxmon/hal/imgsensor/src/#ifdefined(OV5648_MIPI_RAW)　　RAW_INFO(OV5648MIPI_SENSOR_ID,SENSOR_DRVN

6、AME_OV5648_MIPI_RAW,NULL),#endif　　/mediatek/custom/xxmon/kernel/imgsensor/src/kd_#ifdefined(OV5648_MIPI_RAW)　　{OV5648MIPI_SENSOR_ID,SENSOR_DRVNAME_OV5648_MIPI_RAW,OV5648MIPISensorInit},#endif　　Camera电所在文件：　　/mediatek/custom/brighter89_evdo_jb2/kernel/camera/camera/kd_camera_核心驱动文件：　　/

7、mediatek/custom/xxmon/kernel/imgsensor/src/kd_　　如果修改HAL层参数编译命令如下：　　./makeMtk-tbrighter89_evdo_jb2mmmediatek/platform/mt6589/hardware/camera/　　下修改：CUSTOM_HAL_LENS=dw9714af　　CUSTOM_HAL_MAIN_LENS=dw9714afCUSTOM_KERNEL_LENS=dw9714af　　CUSTOM_KERNEL_MAIN_LENS=dw9714af　　添加对应的文件夹和驱动文件　　/G616/
