-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, unless support is provided to switch between modes
-    dynamically.

-Examples:
-
-	uart1: serial@48022000 {
-		compatible = "ti,am3352-uart", "ti,omap3-uart";
-		ti,hwmods = "uart2";
-		clock-frequency = <48000000>;
-		reg = <0x48022000 0x2000>;
-		interrupts = <73>;
-		dmas = <&edma 28 0>, <&edma 29 0>;
-		dma-names = "tx", "rx";
-		dtr-gpios = <&gpio2 22 GPIO_ACTIVE_LOW>;
-		dsr-gpios = <&gpio2 23 GPIO_ACTIVE_LOW>;
-		dcd-gpios = <&gpio2 24 GPIO_ACTIVE_LOW>;
-		rng-gpios = <&gpio2 25 GPIO_ACTIVE_LOW>;
-		cts-gpios = <&gpio0 12 GPIO_ACTIVE_LOW>;
-		rts-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
-	};
-
-	scifa4: serial@e6c80000 {
-		compatible = "renesas,scifa-sh73a0", "renesas,scifa";
-		reg = <0xe6c80000 0x100>;
-		interrupts = <GIC_SPI 78 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&mstp2_clks SH73A0_CLK_SCIFA4>;
-		clock-names = "fck";
-		power-domains = <&pd_a3sp>;
-		uart-has-rtscts;
-	};
