As you commented, extcon must need to document the update and usage method of extcon core.
The mainline kernel includes only the 'Documentation/extcon/porting-android-switch-class'.
Namely, the mainline kernel have not included the document showing the usage method of extcon core.

So, I'll make the proper document for extcon core as later job.

Thanks,
Chanwoo Choi
