Linux Driver Model-general Linux technology-Linux programming and kernel information. The following is a detailed description. Platform_driver_register
Platform_device_register
These two functions are the functions used to register the platform bus device and driver.
The bus device driver is connected through these two functions.
But there is no operation function (read write, etc.) in the driver structure. This is my misunderstanding. 1. I didn't understand the meaning of this drive.
Can you help me explain it? What is the role of the driver registered by platform_driver_register? WHO provides the read write operation for the device registered with platform_device_register or whether their read/write operations are in another mode?
