Subject: [PATCH v2 4/8] phy: phy-rockchip-inno-usb2: support standalone phy nodes
Date: Thu, 12 Aug 2021 16:41:12 -0400	[thread overview]
Message-ID: <20210812204116.2303617-5-pgwipeout@gmail.com> (raw)
In-Reply-To: <20210812204116.2303617-1-pgwipeout@gmail.com>

New Rockchip devices have the usb2 phy devices as standalone nodes
instead of children of the grf node.
Allow the driver to find the grf node from a phandle.
