The exact error that happened trying to get the VBUS supply can be
useful to troubleshoot what's going on.

If the connector is the child of a USB port and that USB port already
has a VBUS supply attached to it, it would be redundant to require the
connector to have a VBUS supply. In this case, allow the VBUS supply to
be optional.

Register a power supply charger, whose online state depends on whether
the USB role is set to device or not.
This is useful when the USB role is the only way to know if the device
is charging from USB. The API is the standard power supply charger API,
you get a /sys/class/power_supply/xxx/online node which tells you the
state of the charger.
The sole purpose of this is to give userspace applications a way to
know whether or not the charger is plugged.

This block lacks a title and argument descriptions.
Fixes the following W=1 kernel build warning:
drivers/usb/common/usb-conn-gpio.c:44: warning: Cannot understand * "DEVICE" = VBUS and "HOST" = !ID, so we have:
on line 44 - I thought it was a doc line

This patch makes the printout of the error message for failing to get a
VBUS regulator handle conditional on the error code being something other
than -EPROBE_DEFER.
Deferral is a normal thing, we don't need an error message for this.

Due to the requirement of usb-connector.txt binding, the old way
using extcon to support USB Dual-Role switch is now deprecated
when use Type-B connector.
This patch introduces a USB GPIO based connection detection driver,
used to support Type-B connector which typically uses an input GPIO
to detect USB ID pin, and try to replace the function provided
by the extcon-usb-gpio driver
