Hans de Goede c42a880c31 extcon: intel-cht-wc: Ignore failure to detect charger-type on host mode exit
When we leave host-mode because the id-pin is no longer connected to
ground, the 5v boost converter is normally still on, so we will see
Vbus, but it is not from a charger (normally) so the charger-type
detection will fail.

This commit silences the cht_wc_extcon_get_charger() false-positive
errors when we're leaving host mode.

Hans de Goede 585cb239f4 extcon: intel-cht-wc: Disable external 5v boost converter on probe
Disable the 5v boost converter on probe in case it was left on by
the BIOS, this fixes 2 problems:

1) This gets seen by the external battery charger as a valid Vbus
   supply and it then tries to feed Vsys from this creating a
   feedback loop which causes aprox. 300 mA extra battery drain
   (and unless we drive the external-charger-disable pin high it
   also tries to charge the battery causing even more feedback).
2) This gets seen by the pwrsrc block as a SDP USB Vbus supply

Since the external battery charger has its own 5v boost converter
which does not have these issues, we simply turn the separate
external 5v boost converter off and leave it off entirely.

Chanwoo Choi bc9a5c37a5 Merge branch 'ib-extcon-4.12' into HEAD 2017-04-06 10:54:36 +09:00
Chanwoo Choi 815429b39d extcon: Add new extcon_register_notifier_all() to monitor all external connectors
The extcon core already provides the extcon_register_notifier() function
in order to register the notifier block which is used to monitor
the state change for the specific external connector such as EXTCON_USB,
EXTCON_USB_HOST and so on. The extcon consumer uses the this function.

The extcon consumer might need to monitor the all supported external
connectors from the extcon device. In this case, The extcon consumer
should have each notifier_block structure for each external connector.

This patch adds the new extcon_register_notifier_all() function
that extcon consumer is able to monitor the state change of all
supported external connectors by using only one notifier_block structure.

- List of new added functions:
int extcon_register_notifier_all(struct extcon_dev *edev,
			struct notifier_block *nb);
int extcon_unregister_notifier_all(struct extcon_dev *edev,
			struct notifier_block *nb);
int devm_extcon_register_notifier_all(struct device *dev,
			struct extcon_dev *edev, struct notifier_block *nb);
void devm_extcon_unregister_notifier_all(struct device *dev,
			struct extcon_dev *edev, struct notifier_block *nb);

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

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).

Hans de Goede 7688424139 extcon: axp288: Remove dependency on non-existing platform_data
When the extcon_axp288 driver was originally merged, it was merged with
a dependency on some other driver providing platform data for it.

However such another driver was never merged, so the extcon_axp288 as
merged upstream has never worked, its probe method simply always returns
-ENODEV.

This commit drops the dependency on the pdata always being there, instead
it treats not having pdata as the pdata having a NULL gpio_mux_control,
something which the code was already prepared to handle.

Note that the code for controlling the mux_control gpio is left in place,
as this may be necessary to allow the axp288 pmic to properly detect the
charger type (instead of assuming 500mA max charge current) on some
tablets. This will make it easier for future patches to add support for
this gpio by getting the gpio info from somewhere.

Linus Torvalds ce38207f16 sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible
 - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
   Intel skylake, atom-sst
 - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
   Realtek RT5665
 
 USB-audio:
 - Yet another race fix at disconnection
 - Tolerated packet size calculation for some Android devices
 - Quirks for Axe-Fx II, QuickCam, TEAC 501/503
 
 HD-audio:
 - Improvement of Dell pin fixup mapping
 - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
 
 Misc:
 - Replace all kthread usages with simple works

Merge tag 'sound-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "No dramatic changes are found in this development cycle, but as usual,
  many commits are applied in a wide range of drivers.

  Most of big changes are in ASoC, where a few bits of framework work
  and quite a lot of cleanups and improvements to existing code have
  been done. The rest are usual stuff, a few HD-audio and USB-audio
  quirks and fixes, as well as the drop of kthread usages in the whole
  subsystem.

  Below are some highlights:

  ASoC:
   - support for stereo DAPM controls
   - some initial work on the of-graph sound card
   - regmap conversions of the remaining AC'97 drivers
   - a new version of the topology ABI; this should be backward
     compatible
   - updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
     Intel skylake, atom-sst
   - new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
     Realtek RT5665

  USB-audio:
   - yet another race fix at disconnection
   - tolerated packet size calculation for some Android devices
   - quirks for Axe-Fx II, QuickCam, TEAC 501/503

  HD-audio:
   - improvement of Dell pin fixup mapping
   - quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic

  Misc:
   - replace all kthread usages with simple works"

Richard Fitzgerald efd95c71f4 extcon: arizona: Use SoC component pin control functions
The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

Roger Quadros 541332a13b 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

Stephen Boyd 2925d366f4 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.

Stephen Boyd 38085c987f 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.

Chanwoo Choi 8670b45980 extcon: Use the extcon_set_state_sync() instead of deprecated functions
This patch alters the renamed extcon API to set the state of the external
connectors instead of deprecated extcon_set_cable_state_().

Because the patch[1] modifies the function name to maintain the function
naming pattern.
- extcon_set_cable_state_() -> extcon_set_state_sync()
- extcon_get_cable_state_() -> extcon_get_state()
