[ Upstream commit 00053de522 ]
Microphone detection provides the button detection features on the
Arizona CODECs as such it will be running if the jack is currently
inserted. If the driver is unbound whilst the jack is still inserted
this will cause warnings from the regulator framework as the MICVDD
regulator is put but was never disabled.
Correct this by disabling microphone detection on driver removal and if
the microphone detection was running disable the regulator and put the
runtime reference that was currently held.

[ Upstream commit 5757aca101 ]
The vbus-present bit in the power status register also gets set to 1
when a usb-host cable (id-pin shorted to ground) is plugged in and a 5v
boost converter is supplying 5v to the otg usb bus.
This causes a "disconnect or unknown or ID event" warning in dmesg as
well as the extcon device to report the last detected charger cable
type as being connected even though none is connected.
This commit switches to checking the vbus-valid bit instead, which is
only 1 when both vbus is present and the vbus-path is enabled in the
vbus-path control register (the vbus-path gets disabled when a usb-host
cable is detected, to avoid the pmic drawing power from the 5v boost
converter).

This patch adds the synchronization extcon APIs to support the notifications
for both state and property. When extcon_*_sync() functions is called,
the extcon informs the information from extcon provider to extcon client.
The extcon driver may need to change the both state and multiple properties
at the same time. After setting the data of a external connector,
the extcon send the notification to client driver with the extcon_*_sync().
The list of new extcon APIs as following:
- extcon_sync() : Send the notification for each external connector to
synchronize the information between extcon provider driver
and extcon client driver.
- extcon_set_state_sync() : Set the state of external connector with noti.
- extcon_set_property_sync() : Set the property of external connector with noti.
For example,
case 1, change the state of external connector and synchronized the data.
extcon_set_state_sync(edev, EXTCON_USB, 1);
case 2, change both the state and property of external connector
and synchronized the data.
extcon_set_state(edev, EXTCON_USB, 1);
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_ID, 1);
extcon_sync(edev, EXTCON_USB);
case 3, change the property of external connector and synchronized the data.
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0);
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_ID, 1);
extcon_sync(edev, EXTCON_USB);
case 4, change the property of external connector and synchronized the data.
extcon_set_property_sync(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0);

Splitting the resource-managed functions into a separate module
means that the extcon core now fails to build because the internal
"extcon_dev_allocate" symbol is not exported:
ERROR: extcon_dev_allocate [drivers/extcon/devres.ko] undefined!
My guess is that the intention was not to have two separate
modules (which could be fixed by adding an export, plus the
normal MODULE_AUTHOR/MODULE_LICENSE/... fields), but have two
source files in the same module.
This fixes the Makefile accordingly, making the name of the
module extcon_core.ko, which is created from building both
extcon.c and devres.c.

Use resource managed functions devm_usb_get_phy and
devm_gpio_request to make error path simpler. To be
compatible the change, various gotos are replaced
with direct returns and unnecessary label
gpio_req_failed is dropped.
Also, remove function axp288_extcon_remove as it is
now redundant.

The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: I2C id table or OF match table).
So drivers needs to export the I2C id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
But this means that OF-only drivers needs to have both OF and I2C id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same I2C device name for example.
To avoid the above, the I2C core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

Whilst the jack is connected we disable the jack detection debounce to
ensure as quick as possible a detection of jack removal. However, it is
only safe to disable the jack debounce whilst the jack is connected if
using the micd clamp or the jack is not inverted. Otherwise spurious
interrupts might be generated when we re-enable the debounce.

Currently we only use the microphone clamp IRQ if GPIO5 is being used as
a second jack detection pin. But we should be using it on any system
where the clamp is available. This patch updates the driver to do so.

If the TST_CAP_SEL bits aren't set correctly on wm5110/8280 there will
be a 100k load along side the headphones, which will affect the accurary
towards the very top of the detection range. This patch sets those bits.

Newer devices give users the option to make the 3/4 pole jack
determination using a software comparison rather than a hardware one.
This patch adds support for this functionality.
