This patch add support irq domain for Maxim MAX8997 muic
instead of irq_base in platform data and max8997 driver
private data are instead. It is tested on TRATS board.

This patch support Maxim MAX77693 MUIC device by using EXTCON Subsystem
to handle various external connector. The extcon-max77693 use regmap
method for i2c communication and support irq domain instead of previous
method of irq base.

Most Wolfson Arizona class audio hub CODECs include a flexible ultra low
power accessory detection subsystem. This driver exposes initial support
for this subsystem via the Extcon framework, implementing support for
ultra low power detection of headphone and headset with the ability to
detect the polarity of a headset.
The functionality of the devices is much richer and more flexible than
the current driver, future patches will extend the features of the
driver to more fully exploit this.

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.

Changed from v7:
- Style updates mentioned by Stephen Boyd and Mark Brown
Changed from v5:
- Splitted at v5 from the main extcon patch.
- Added debounce time for irq handlers.
- Use request_any_context_irq instead of request_irq
- User needs to specify irq flags for GPIO interrupts (was fixed to
IRQF_TRIGGER_LOW before)
- Use module_platform_driver().

External connector class (extcon) is based on and an extension of
Android kernel's switch class located at linux/drivers/switch/.
This patch provides the before-extension switch class moved to the
location where the extcon will be located (linux/drivers/extcon/) and
updates to handle class properly.
The before-extension class, switch class of Android kernel, commits
imported are:
switch: switch class and GPIO drivers. (splitted)
Author: Mike Lockwood <lockwood@android.com>
switch: Use device_create instead of device_create_drvdata.
Author: Arve Hjønnevåg <arve@android.com>
In this patch, upon the commits of Android kernel, we have added:
- Relocated and renamed for extcon.
- Comments, module name, and author information are updated
- Code clean for successing patches
- Bugfix: enabling write access without write functions
- Class/device/sysfs create/remove handling
- Added comments about uevents
- Format changes for extcon_dev_register() to have a parent dev.
