This patch add extcon-max8997 driver to support the muic feature of Maxim max8997 by using Extcon framework. The extcon-max8997 driver is implemented based on 'drivers/misc/ max8997-muic.c' and then use Extcon interface instead of callback function in struct max8997_muic_platform_data to notify cable state of notifee which want to know always newly cable state when external connector(e.g., USB, TA, JIG) is attached or detached. v1 - Use Extcon interface to notify cable state of notifee instead of callback function when external connector is attached or detached. - Bug fix of getting platform_data for irq_base value.

Say Y here to enable external connector class (extcon) support.
|
|
This allows monitoring external connectors by userspace
|
|
via sysfs and uevent and supports external connectors with
|
|
multiple states; i.e., an extcon that may have multiple
|
|
cables attached. For example, an external connector of a device
|
|
may be used to connect an HDMI cable and a AC adaptor, and to
|
|
host USB ports. Many of 30-pin connectors including PDMI are
|
|
also good examples.

If you say yes here you get support for the MUIC device of
|
|
Maxim MAX8997 PMIC. The MAX8997 MUIC is a USB port accessory
|
|
detector and switch.
