extcon: palmas: Check the parent instance to prevent the NULL
[ Upstream commit 9fe172b9be532acc23e35ba693700383ab775e66 ]

extcon-palmas must be child of palmas and expects parent's
drvdata to be valid. Check for non NULL parent drvdata and
fail if it is NULL. Not doing so will result in a NULL
pointer dereference later in the probe() parent drvdata
is NULL (e.g. misplaced extcon-palmas node in device tree).

extcon: Remove potential problem when calling extcon_register_notifier()
[ Upstream commit 01b4c9a1ae07a25d208cad0da7dd288007a22984 ]

This patch removes the potential problem of extcon_register_notifier()
when edev parameter is NULL. When edev is NULL, this function returns
the first extcon device which includes the sepecific external connector
of second paramter. But, it don't guarantee the same operation in all cases.
To remove this confusion and potential problem, this patch fixes it.

extcon: axp288: Use vbus-valid instead of -present to determine cable presence
[ Upstream commit 5757aca10146061befd168dab37fb0db1ccd8f73 ]

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).

extcon: gpio: add support to parse platform data from device tree
extcon-gpio driver currently doesn't support passing the platfroom data via
device tree, we are adding this support so extcon-gpio driver can be used
with platforms using the DT from platform data. We are also fixing the
issue where we were passing the supported_cable incorrect way to
extcon_dev_allocate() API.

extcon: usb-gpio: Add VBUS detection support
Driver can now work with both ID and VBUS pins or either one of
them.

There can be the following 3 cases

1) Both ID and VBUS GPIOs are available:

ID = LOW -> USB_HOST active, USB inactive
ID = HIGH -> USB_HOST inactive, USB state is same as VBUS.

2) Only ID GPIO is available:

ID = LOW -> USB_HOST active, USB inactive
ID = HIGH -> USB_HOST inactive, USB active

3) Only VBUS GPIO is available:

VBUS = LOW -> USB_HOST inactive, USB inactive
VBUS = HIGH -> USB_HOST inactive, USB active

extcon: return error code on failure
commit 5b11ebedd6a8bb4271b796e498cd15c0fe1133b6 upstream.

Function get_zeroed_page() returns a NULL pointer if there is no enough
memory. In function extcon_sync(), it returns 0 if the call to
get_zeroed_page() fails. The return value 0 indicates success in the
context, which is incosistent with the execution status. This patch
fixes the bug by returning -ENOMEM.

extcon: qcom-spmi-misc: Sync the extcon state on interrupt
The driver was changed after submission to use the new style APIs
like extcon_set_state(). Unfortunately, that only sets the state,
and doesn't notify any consumers that the cable state has
changed. Use extcon_set_state_sync() here instead so that we
notify cable consumers of the state change. This fixes USB
host-device role switching on the db8074 platform.

extcon: Add support for qcom SPMI PMIC USB id detection hardware
Some Qualcomm PMICs have a misc device that performs USB id pin
detection via an interrupt. When the interrupt triggers, we
should read the interrupt line to see if it has gone high or low.
If the interrupt is low then the ID pin is grounded, and if the
interrupt is high then the ID pin is being held high.

extcon: Add the synchronization extcon APIs to support the notification
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

The list of new extcon APIs as following:

- 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_VBUS 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_sync(edev, EXTCON_USB);

case 4, change the property of external connector and synchronized the data.

- EXTCON_TYPE_CHG  : Charger connector
- EXTCON_TYPE_JACK : Jack connector
- EXTCON_TYPE_DISP : Display connector
- EXTCON_TYPE_MISC : Miscellaneous connector

Also, each external connector is possible to belong to one more extcon type.
In caes of EXTCON_CHG_USB_SDP, it have the EXTCON_TYPE_CHG and EXTCON_TYPE_USB.

extcon: Block the bit masking operation for cable state except for extcon core
This patch restrict the usage of extcon_update_state() in the extcon
core because the extcon_update_state() use the bit masking to change
the state of external connector. When this function is used in device drivers,
it may occur the probelm with the handling mistake of bit masking.

Also, this patch removes the extcon_get/set_state() functions because these
functions use the bit masking which is reluctant way. Instead, extcon
provides the extcon_set/get_cable_state_() functions.

extcon: gpio: Remove the usage of extcon_set_state()
This patch removes the usage of extcon_set_state() because it uses
the bit masking to change the state of external connectors. The extcon framework
should handle the state by extcon_set_cable_state_() with extcon id.

extcon: arizona: Remove the usage of extcon_update_state()
This patch remvoes the usage of extcon_update_state() because
the extcon_update_state() use directly the bit masking calculation
to change the state of external connector without the unique id of
external connector. It makes the code diffcult to read it.
So, this patch uses the extcon_set_cable_state_() instead.

extcon: Move extcon_get_edev_by_phandle() errors to dbg level
Sometimes drivers may call this API and expect it to fail because
the extcon they're looking for is optional. Let's move these
prints to debug level so it doesn't look like there's a problem
when there isn't one.
