+The pin module, also called pin controller, manages pin resources of system on a chip (SoC) vendors and provides the pin multiplexing function.
+The module defines a set of common methods for managing pins, including:
     -   Obtaining or releasing the pin description handle: The kernel compares the pin name passed in with the pin names of each controller in the linked list. If a match is found, a pin description handle is obtained. After the operation on the pin is complete, the pin description handle will be released.
-    -   Setting or obtaining the pull type of a pin: The pull type can be pull-up, pull-down, or floating.
-    -   Setting or obtaining the pull strength of a pin: You can set the pull strength as required.
-    -   Setting or obtaining the functions of a pin to implement pin multiplexing

 ### Basic Concepts<a name="section3"></a>
 Pin, as a software concept, provides APIs for uniformly managing the pins from different SoC vendors, providing the pin multiplexing function, and configuring the electrical features of pins.
