Subject: [PATCH 4/4] dt-bindings: phy-rockchip-inno-usb2: add new rockchip,force-bvalid property.
Date: Wed, 15 Aug 2018 11:59:34 +0200	[thread overview]
Message-ID: <20180815095934.11205-5-enric.balletbo@collabora.com> (raw)
In-Reply-To: <20180815095934.11205-1-enric.balletbo@collabora.com>

This property is used when the otg-id pin is not connected. When this
property is set it forces to set the B-Device Session Valid bit when the
port works as device and clears that bit when the port works as host.
