Subject: linux-next: manual merge of the tty tree with the devicetree tree

Hi Greg,

Today's linux-next merge of the tty tree got a conflict in
Documentation/devicetree/bindings/serial/pl011.txt between commit
a81a6c654bbe ("ARM: dt: fix up PL011 device tree bindings") from the
devicetree tree and commit 98267d33e2da ("serial: pl011: Add device
tree support for RX DMA polling") from the tty tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

@@@ -6,34 -6,17 +6,39 @@@ Required properties
  - interrupts: exactly one interrupt specifier
  
  Optional properties:
 -- pinctrl:		When present, must have one state named "sleep"
 -			and one state named "default"
 -- clocks:		When present, must refer to exactly one clock named
 -			"apb_pclk"
 -- dmas:			When present, may have one or two dma channels.
 -			The first one must be named "rx", the second one
 -			must be named "tx".
 +- pinctrl: When present, must have one state named "default",
 +	   and may contain a second name named "sleep". The former
 +	   state sets up pins for ordinary operation whereas
 +	   the latter state will put the associated pins to sleep
 +	   when the UART is unused
 +- clocks:  When present, the first clock listed must correspond to
 +	   the clock named UARTCLK on the IP block, i.e. the clock
 +	   to the external serial line, whereas the second clock
 +	   must correspond to the PCLK clocking the internal logic
 +	   of the block. Just listing one clock (the first one) is
 +	   deprecated.
 +- clocks-names: When present, the first clock listed must be named
 +	   "uartclk" and the second clock listed must be named
 +	   "apb_pclk"
 +- dmas:	   When present, may have one or two dma channels.
 +	   The first one must be named "rx", the second one
 +	   must be named "tx".
+ - auto-poll:		Enables polling when using RX DMA.
+ - poll-rate-ms:		Rate at which poll occurs when auto-poll is set,
+ 			default 100ms.
+ - poll-timeout-ms:	Poll timeout when auto-poll is set, default
+ 			3000ms.
