  serial@8006a000: compatible: ['fsl,imx28-auart', 'fsl,imx23-auart']
  is too long

-	"fsl,imx28-auart" - Freescale i.MX28
-	"alphascale,asm9260-auart" - Alphascale ASM9260
-- reg : Address and length of the register set for the device

-
-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
