From b76668ba8a7722f589af2e13a340f3629430a35a Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Wed, 9 May 2012 12:31:58 +0900 Subject: Extcon: add MAX8997 extcon driver 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.
