Subject: [PATCH v17 4/7] arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub
Date:   Tue, 16 Nov 2021 12:07:36 -0800
Message-Id: <20211116120642.v17.4.Ie0d2c1214b767bb5551dd4cad38398bd40e4466f@changeid>
In-Reply-To: <20211116200739.924401-1-mka@chromium.org>

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.
