Subject: [PATCH v10 5/5] arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub
Date: Tue, 11 May 2021 15:52:23 -0700
Message-ID: <20210511155152.v10.5.Ie0d2c1214b767bb5551dd4cad38398bd40e4466f@changeid> (raw)
In-Reply-To: <20210511225223.550762-1-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.

Signed-off-by: Matthias Kaehlcke <mka@chromium.org>
