Linux下v4l2-camera子系统之sensor驱动(三)平台：君正x1000linux kernel: 3.10camera sensor：ov7725在Linux下v4l2-camera子系统之soc_camera_device(二)和Linux下v4l2-camera子系统之soc_camera_host(三)中已经分析了ov7725注册进camera_device并用i2c_new_device(adapter, info)创建一个client，然后就会和驱动匹配，进入驱动的probe

Linux下v4l2-camera子系统之soc_camera_host(三)平台：君正x1000linux kernel: 3.10camera sensor：ov7725上节分析了camera_device感觉并没接触到核心，那么camera_host就该完成关键代码了。Camera_host设备static struct resource jz_cim_resources[] = { [0] = { .flags = IORESOURCE_MEM, .start = CIM_IO

Linux下v4l2-camera子系统分soc_camera_device(二)平台：君正x1000linux kernel: 3.10camera sensor：ov7725上节认识了camera子系统的大概框架结构及主要相关结构，现在看看系统中是怎么注册camera_device。struct i2c_board_info jz_v4l2_camera_devs[] __initdata = { { I2C_BOARD_INFO("ov7725", 0x21), },
