-* Freescale MXS Application UART (AUART)
-
-Required properties for all SoCs:
-- compatible : Should be one of fallowing variants:
-	"fsl,imx23-auart" - Freescale i.MX23
-	"fsl,imx28-auart" - Freescale i.MX28
-	"alphascale,asm9260-auart" - Alphascale ASM9260
-- reg : Address and length of the register set for the device
-- interrupts : Should contain the auart interrupt numbers
-- dmas: DMA specifier, consisting of a phandle to DMA controller node
-  and AUART DMA channel ID.
-  Refer to dma.txt and fsl-mxs-dma.txt for details.
-- dma-names: "rx" for RX channel, "tx" for TX channel.
-
-Required properties for "alphascale,asm9260-auart":
-- clocks : the clocks feeding the watchdog timer. See clock-bindings.txt
-- clock-names : should be set to
-	"mod" - source for tick counter.
-	"ahb" - ahb gate.
-
-Optional properties:
-- uart-has-rtscts : Indicate the UART has RTS and CTS lines
-  for hardware flow control,
-	it also means you enable the DMA support for this UART.
-- {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
-  line respectively. It will use specified PIO instead of the peripheral
-  function pin for the USART feature.
-  If unsure, don't specify this property.
-
-Example:
-auart0: serial@8006a000 {
-	compatible = "fsl,imx28-auart", "fsl,imx23-auart";
-	reg = <0x8006a000 0x2000>;
-	interrupts = <112>;
-	dmas = <&dma_apbx 8>, <&dma_apbx 9>;
-	dma-names = "rx", "tx";
-	cts-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;
-	dsr-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
-	dcd-gpios = <&gpio1 17 GPIO_ACTIVE_LOW>;
-};
-
-Note: Each auart port should have an alias correctly numbered in "aliases"
-node.
-
-Example:
-
-aliases {
-	serial0 = &auart0;
-	serial1 = &auart1;
-	serial2 = &auart2;
-	serial3 = &auart3;
-	serial4 = &auart4;
-};
