-* RS485 serial communications
-
-The RTS signal is capable of automatically controlling line direction for
-the built-in half-duplex mode.
-The properties described hereafter shall be given to a half-duplex capable
-UART node.
-
-Optional properties:
-- rs485-rts-delay: prop-encoded-array <a b> where:
-  * a is the delay between rts signal and beginning of data sent in milliseconds.
-      it corresponds to the delay before sending data.
-  * b is the delay between end of data sent and rts signal in milliseconds
-      it corresponds to the delay after sending data and actual release of the line.
-  If this property is not specified, <0 0> is assumed.
-- rs485-rts-active-low: drive RTS low when sending (default is high).
-- linux,rs485-enabled-at-boot-time: empty property telling to enable the rs485
-  feature at boot time. It can be disabled later with proper ioctl.
-- rs485-rx-during-tx: empty property that enables the receiving of data even
-  while sending data.

-RS485 example for Atmel USART:
-	usart0: serial@fff8c000 {
-		compatible = "atmel,at91sam9260-usart";
-		reg = <0xfff8c000 0x4000>;
-		interrupts = <7>;
-		atmel,use-dma-rx;
-		atmel,use-dma-tx;
-		linux,rs485-enabled-at-boot-time;
-		rs485-rts-delay = <0 200>;		// in milliseconds
-	};
