5 Provide a place in sysfs for the extcon objects.
6 This allows accessing extcon specific variables.
7 The name of extcon object denoted as ... is the name given
10 One extcon device denotes a single external connector
22 What: /sys/class/extcon/.../name
26 The /sys/class/extcon/.../name shows the name of the extcon
27 object. If the extcon object has an optional callback
