extcon: intel-cht-wc: Ignore failure to detect charger-type on host mode exit

2017-04-06T01:55:26+00:00

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.

extcon: intel-cht-wc: Disable external 5v boost converter on probe

2017-04-06T01:55:25+00:00

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.

over a couple of years.

The USB cable state can change during suspend/resume
so be sure to check and update the extcon state.

extcon: usb-gpio: Don't miss event during suspend/resume

2017-04-06T01:55:21+00:00

We must check for ID/VBUS changes during resume irrespective
of whether our device wakeup is enabled or not.

Without this we seem to be missing ID/VBUS events after
system suspend/resume.

extcon: usb-gpio: Do not enable USB as wakeup source by default

2017-04-06T01:55:20+00:00

Whether the USB port as a wakeup source should be determined by user,
but not enabled by default.

extcon: arizona: Wait for any running HPDETs to complete on jack removal

2017-04-06T01:55:19+00:00

As the HPDET can't be aborted mid way through we should not allow any new
insertion to be processed until the previous HPDET has finished. It is very
unlikely but with low enough debounce settings you could start a new HPDET
before the old one has completed, which results in an erroneous reading.
