Add support for MAX77836 chipset to the max14577 extcon driver. The
MAX77836 MUIC has additional interrupts (VIDRM, ADC1K) so IRQ handling
is split up into two functions: max14577_parse_irq() and
max77836_parse_irq().

This patch continues the preparation for adding support for max77836
device to existing max14577 driver.
During probe choose muic_irqs according to device type. Currently there
are only "max14577_muic_irqs" but later patch will add max77836
interrupts.

commit ca488 (extcon: of: Remove unnecessary function call by using the
name of device_node) started using node name instead of device name
to get the extcon device. This breaks dwc3-omap since it's not able to
get the extcon device anymore. Fixed it by setting edev name of
palmas to be the same as its node name.

The snd_soc_dapm_xxxx_pin all require the dapm_mutex to be held when
they are called as they edit the dirty list, however very few of the
callers do so.
This patch adds unlocked versions of all the functions replacing the
existing implementations with one that holds the lock internally. We
also fix up the places where the lock was actually held on the caller
side.

Commit 338de0ca (extcon: gpio: Use gpio driver/chip debounce if supported)
introduced a call to gpio_set_debounce() before actually requesting the
respective gpio pin from the gpio subsystem.
The gpio subsystem expects that a gpio pin was requested before modifying its
state. Not doing so results in a warning from gpiolib, and the gpio pin is
auto-requested. This in turn causes the subsequent devm_gpio_request_one()
to fail. So devm_gpio_request_one() must be called prior to calling
gpio_set_debounce().

extcon_dev_unregister -> kfree(edev->extcon_dev_type.groups)
then device_unregister -> device_del -> device_remove_attrs

panic because type->groups has been freed.
This patch is move device_unregister ahead of groups free
to avoid panic in extcon_dev_unregister.

In the case of a device tree system there will be no pdata attached to
the device, causing us to deference a NULL pointer. Better to take the
pdata from the Arizona structure as this will always exist and we know
will have been populated since it is populated by the MFD device which
binds in the extcon driver.

Update extcon for 3.13
This patchset modify extcon core to remove unnecessary allocation sequence for
'dev' instance and change extcon_dev_register() interface. extcon-gpio use
gpiolib API to get debounce time and include small fix of extcon core/device
driver.
Detailed description for patchset:
1. Modify extcon core driver
- The extcon-gpio driver use gpio_set_debounce() API provided from gpiolib
if gpio driver for SoC support gpio_set_debounce() function and support 'gpio_
activ_low' filed to check whether gpio active state is 1(high) or 0(low).
- Change field type of 'dev' in structure extcon_dev and remove the sequence
of allocating memory of 'struct dev' on extcon_dev_register() function because
extcon device must need 'struct device.
- Change extcon_dev_register() prototype to simplify it and remove unnecessary
parameter as below:
2. Fix coding style and typo
- extcon core : Fix indentation coding style and remove unnecessary casting
- extcon-max8997 : Fix checkpatch warning
- extcon-max77693 : Fix checkpatch warning
- extcon-arizona : Fix typo of comment and modify minor issue
- extcon-palmas : Use dev_get_platdata()
3. Modify extcon-arizona driver
- Modify minor issue about micbias and comparision statement

parameter
This patch remove extcon_dev_register()'s second parameter which means
the pointer of parent device to simplify prototype of this function.
So, if extcon device has the parent device, it should set the pointer of
parent device to edev.dev.parent in extcon device driver instead of in
extcon_dev_register().

Every other pdata field is specified unshifted the patch handles
shifting for the MICBIAS from the microphone detection polarity
configurations in the extcon driver rather than demanding it in
pdata to match other fields.

We want the trig_sts bits to be cleared in all cases where we consider
the jack detection interrupt to have been handled. Specifically, if a
duplicate detection event was suppressed these bits were not cleared
causing the CODEC to not enter a low power state. This patch clears the
bits on the duplicate detection code path.

Lots of tiny changes here fixing up the way sysfs attributes are
created, to try to make drivers simpler, and fix a whole class race
conditions with creations of device attributes after the device was
announced to userspace.
All the various pieces are acked by the different subsystem
maintainers"

The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the extcon_class code to use the
correct field.

None of the delayed work the driver schedules has particularly short delays
and it is not performance sensitive so let the scheduler run it wherever
is most efficient rather than in a per CPU workqueue by using the system
power efficient workqueue.
