[PATCH v4 0/3] Add MAX14526 MUIC driver

[Svyatoslav Ryhel]

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.
