From: Heiko Stuebner <redacted> RS485 has two signals to control transmissions "driver enable" (DE) and "receiver enable" (RE). DE is already handled via the uarts RTS signal while the RE signal on most implementations doesn't get handled separately at all. As there still will be cases where this is needed though add a gpio property for declaring this signal pin.
