The Extcon (External Connector) subsystem driver lacked proper
documentation. This commit adds comprehensive documentation
explaining the purpose, key components, and usage of the Extcon
framework.
The new documentation includes:
- An overview of the Extcon subsystem
- Descriptions of key structures
- Explanations of core functions
- Information on the sysfs interface
- A usage example for driver developers
