Merge tag 'tty-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty and serial driver updates from Greg KH:
 "Here's the large TTY and Serial driver update for 4.7-rc1.

  A few new serial drivers are added here, and Peter has fixed a bunch
  of long-standing bugs in the tty layer and serial drivers as normal.
  Full details in the shortlog.

  All of these have been in linux-next for a while with no reported
  issues"

 * Freescale MXS Application UART (AUART)
 
-Required properties:
-- compatible : Should be "fsl,<soc>-auart". The supported SoCs include
-  imx23 and imx28.
+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
@@ -10,8 +12,14 @@ Required properties:
   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:
-- fsl,uart-has-rtscts : Indicate the UART has RTS and CTS lines
+- 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.
