MAX14526 MUIC is used by LG P880/P895 which are currently in the process of merging.
MAX14526 is a powerful extcon device which has the ability to accurately determine plugged devices. In this implementation muic can be configured to represent 3 modes: CP-USB/UART and AP-USB. Unfortunately AP-UART was disabled on P880/P895. Additionally the driver configures some stuff required by the charger.
Extcon class has empty platform struct and ops, all configuration is performed in the probe. Filling of struct and ops is welcomed.
--- Changes from v2: - created a new simple extcon uclass
Changes from v1: - used log_* instead of printf - log messages made simpler ---
