1	OMAP UART controller
2	
3	Required properties:
4	- compatible : should be "ti,omap2-uart" for OMAP2 controllers
5	- compatible : should be "ti,omap3-uart" for OMAP3 controllers
6	- compatible : should be "ti,omap4-uart" for OMAP4 controllers
7	- reg : address and length of the register space
8	- interrupts or interrupts-extended : Should contain the uart interrupt
9	                                      specifier or both the interrupt
10	                                      controller phandle and interrupt
11	                                      specifier.
12	- ti,hwmods : Must be "uart<n>", n being the instance number (1-based)
13	
14	Optional properties:
15	- clock-frequency : frequency of the clock input to the UART
16	- dmas : DMA specifier, consisting of a phandle to the DMA controller
17	         node and a DMA channel number.
18	- dma-names : "rx" for receive channel, "tx" for transmit channel.
19	
20	Example:
21	
22	                uart4: serial@49042000 {
23	                        compatible = "ti,omap3-uart";
24	                        reg = <0x49042000 0x400>;
25	                        interrupts = <80>;
26	                        dmas = <&sdma 81 &sdma 82>;
27	                        dma-names = "tx", "rx";
28	                        ti,hwmods = "uart4";
29	                        clock-frequency = <48000000>;
30	                };
