A device driver is used as a translation between hardware and the application that uses hardware (user code) or the kernel, which hides the details of the hardware's work behind the scenes, thereby simplifying programming. Programmers can use a set of standardized invocation methods (system calls) to write advanced application code without having to care about the specific hardware it will control or the processor on which it is running. With a well-defined internal application programming inter

compared the linux directory before and after the power plugging, but there was no clue when I looked for it for a long time. Why did I check CPU and memory for commands, check the power supply and there will be no command? Later, I found that this may not exist! I don't know the driver, I don't know the hardware, and I can't use the scripts written by others. I try to understand it. The following is your understanding. Please refer to Hai Han for errors.

The basic idea is to implement a parent device for the public part of these functions, in order to share certain system resources and functions, then each child function is implemented as its sub device, so that both resources and code are shared, and a reasonable device hierarchy can be achieved, the main use of the API is: Mfd_add_devices (), Mfd_remove_devices (), mfd_cell_enable (), mfd_cell_disable (), Mfd_clone_cell ().
