Subject: [PATCH 2/3] dt-bindings: usb: ti,keystone-dwc3.yaml: Add USB3.0 PHY property
Date: Wed, 13 May 2020 16:07:08 +0300	[thread overview]
Message-ID: <20200513130709.10239-3-rogerq@ti.com> (raw)
In-Reply-To: <20200513130709.10239-1-rogerq@ti.com>

AM654 SoC requires USB3.0 PHY to be turned on before the USB controller.
For this SoC, the 'phys' property is used to provide the USB3.0
reference.
