-* ARM AMBA Primecell PL011 serial UART
-
-Required properties:
-- compatible: must be "arm,primecell", "arm,pl011", "zte,zx296702-uart"
-- reg: exactly one register range with length 0x1000
-- interrupts: exactly one interrupt specifier
-
-Optional properties:
-- 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.
-- clock-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.

-Example:
-
-uart@80120000 {
-	compatible = "arm,pl011", "arm,primecell";
-	reg = <0x80120000 0x1000>;
-	interrupts = <0 11 IRQ_TYPE_LEVEL_HIGH>;
-	dmas = <&dma 13 0 0x2>, <&dma 13 0 0x0>;
-	dma-names = "rx", "tx";
-	clocks = <&foo_clk>, <&bar_clk>;
-	clock-names = "uartclk", "apb_pclk";
-};
