66bee35f29 extcon: Fix missing locking when [un]registering notifiers
Since extcon.c is using raw_notifiers it must protect the notifier
list itself when [un]registering notifiers to avoid the list changing while
extcon_update_state is walking the list (through raw_notifier_call_chain).

e52817faae extcon: usb-gpio: Introduce gpio usb extcon driver
This driver observes the USB ID pin connected over a GPIO and
updates the USB cable extcon states accordingly.

The existing GPIO extcon driver is not suitable for this purpose
as it needs to be taught to understand USB cable states and it
can't handle more than one cable per instance.

For the USB case we need to handle 2 cable states.
1) USB (attach/detach)
2) USB-HOST (attach/detach)

This driver can be easily updated in the future to handle VBUS
events in case it happens to be available on GPIO for any platform.

17271f608b extcon: arizona: Get MICVDD against extcon device
Previously we would do a regulator get against the main Arizona device
to obtain the MICVDD regulator. Arizona is an MFD device and normally
MICVDD will be supplied by one of its children (the arizona-micsupp
regulator). As devres destruction for the MFD device will run after all
its children have been destroyed, the regulator will be destroyed before
devres calls regulator_put. This causes a warning from both the
destruction of the child node, as the regulator is still open, and from
the put of the regulator as the regulator device has already been
destroyed.

A simple fix here is to get the regulator against the extcon device
itself such that devres runs when the child is destroyed. This has the
additional benefit that if for some reason the extcon driver is unloaded
the regulator reference won't hang around until the MFD is unloaded.

24a279b1ca extcon: arizona: Update manual headphone detection calculation
The higher levels of impedance have a higher minimum value than the
first level. As the same value was used for all levels, higher impedances
were reported with a very low level of accuracy. This patch applies the
approriate lower threshold for each level, whilst we are changing things
add a define for the maximum value at each level to improve readability.

e368f52521 extcon: arizona: Correct typo to disable regulation for button detection
We can use the bypass mode on the MICVDD reg for button detection, as
the comment in the code states, however the code was mistakenly
disabling bypass. This patch corrects this and allows bypass mode during
button detection.
