+Generic Serial DT Bindings
+
+This document lists a set of generic properties for describing UARTs in a
+device tree.  Whether these properties apply to a particular device depends on
+the DT bindings for the actual device.
+
+Optional properties:
+  - cts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
+    used as the UART's CTS line.
+  - dcd-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
+    used as the UART's DCD line.
+  - dsr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
+    used as the UART's DSR line.
+  - dtr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
+    used as the UART's DTR line.
+  - rng-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
+    used as the UART's RNG line.
+  - rts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
+    used as the UART's RTS line.
+
+  - uart-has-rtscts: The presence of this property indicates that the
+    UART has dedicated lines for RTS/CTS hardware flow control, and that
+    they are available for use (wired and enabled by pinmux configuration).
+    This depends on both the UART hardware and the board wiring.
+    Note that this property is mutually-exclusive with "cts-gpios" and
+    "rts-gpios" above.
+
+
+Examples:
+
+	uart1: serial@48022000 {
+		compatible = "ti,am3352-uart", "ti,omap3-uart";
+		ti,hwmods = "uart2";
+		clock-frequency = <48000000>;

+		rts-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
+		status = "okay";
