Subject: [PATCH v14 6/6] arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub
Add nodes for the onboard USB hub on trogdor devices. Remove the
'always-on' property from the hub regulator, since the regulator
is now managed by the onboard_usb_hub driver.
Signed-off-by: Matthias Kaehlcke <mka@...omium.org>
