Systems Software LTDA. Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org The phy-supply is an optional regulator, so we should not treat as an error when phy-supply is not passed in the device tree. This allows the dwmac-rk driver to probe when phy-supply is not present in the dts.
