Subject: arm64: dts: qcom: msm8916-longcheer-l8150: Use &pm8916_usbin extcon
From: Stephan Gerhold <stephan@xxxxxxxxxxx>
commit b30cad26d8030bddeb0ee2373b6d4c1440ffb1a3 upstream.
At the moment, longcheer-l8150 is using a dummy extcon-usb-gpio device
that permanently enables USB gadget mode. This workaround allows USB
to work but is actually wrong and confusing. The "vbus-gpio" used there
refers to an unused (floating) GPIO that is pulled up to make
extcon-usb-gpio report USB gadget mode permanently.
Replace this with the new &pm8916_usbin extcon device that actually
reports if an USB cable is attached or not. This allows the USB PHY
to be turned off when there is no USB cable attached and is much
cleaner overall.
