然而,一个 module_i2c_driver 宏调用只能注册一个特定的 I2C 设备驱动。 如果你需要处理多个 I2C 设备地址,你需要在设备驱动代码中为每个设备分别注册。这通常意味着你需要为每个设备定义一个 i2c_driver 结构体实例,并使用 i2c_add_driver 或module_driver(通过 module_i2c_driver)来注册它们。
921*/922#definemodule_i2c_driver(__i2c_driver) \923module_driver(__i2c_driver, i2c_add_driver, \924i2c_del_driver) 里面用到 module_driver 也是一个宏,用于简化 重复代码 ; 第一个参数是 struct i2c_driver 对象的名称 ; 是对象的名称,宏内部会对其进行 取地址 操作 ; 第二个参数是 自动生成函数...
了解了上面定义的宏,对于module_i2c_driver(imx588_i2c_driver), 则可以按照宏展开成: static int __init imx588_i2c_driver_init(void) { return i2c_add_driver(&imx588_i2c_driver); } module_init(imx588_i2c_driver_init); static void __exit imx588_i2c_drive_exit(void) { i2c_del_driver(&...
