Subject: [PATCH v9 5/5] arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub
Date: Mon,  3 May 2021 12:44:39 -0700	[thread overview]
Message-ID: <20210503124408.v9.5.Ie0d2c1214b767bb5551dd4cad38398bd40e4466f@changeid> (raw)
In-Reply-To: <20210503194439.3289065-1-mka@chromium.org>

Add nodes for the onboard USB hub on trogdor devices. Remove the
'always-on' and 'boot-on' properties from the hub regulator, since
the regulator is now managed by the onboard_usb_hub driver.

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