Subject: [PATCH 1/3] usb: dwc3: of-simple: Add compatible for rk3328
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add a compatible to be hooked into by the Rockchip rk3328 device tree.

The rk3399 compatible cannot be reused because the rk3328 SoCs may
require a specialized driver in the future, and old device trees must
remain commpatible with newer kernels.
