Sender: devicetree-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: devicetree@vger.kernel.org The 'vin-voltage-override' DT property is used by the trf7970a driver to override the voltage presented to the driver by the regulator subsystem. This is unnecessary as properly specifying the regulator chain via DT properties will accomplish the same thing. Therefore, remove support for 'vin-voltage-override'.
