Subject: [PATCH 1/4] extcon: Unify the jig cable names on RT8963 and
MAX14577/77693/77843
This patch change the name of various jig cables as 'JIG' because the name of
various jig cables are strange and ambiguous on user-space aspect. They include
the different information of either USB and UART state. It is never important
for user-space process. This patch unifies the name of jig cables as following:
- JIG-USB-ON -->|--> JIG
- JIG-USB-OFF -->|
- JIG-UART-ON -->|
- JIG-UART-OFF -->|
