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	- compatible : should be "ti,am4372-uart" for AM437x controllers
8	- compatible : should be "ti,am3352-uart" for AM335x controllers
9	- compatible : should be "ti,dra742-uart" for DRA7x controllers
10	- reg : address and length of the register space
11	- interrupts or interrupts-extended : Should contain the uart interrupt
12	                                      specifier or both the interrupt
13	                                      controller phandle and interrupt
14	                                      specifier.
15	- ti,hwmods : Must be "uart<n>", n being the instance number (1-based)
16	
17	Optional properties:
18	- clock-frequency : frequency of the clock input to the UART
19	- dmas : DMA specifier, consisting of a phandle to the DMA controller
20	         node and a DMA channel number.
21	- dma-names : "rx" for receive channel, "tx" for transmit channel.
22	
23	Example:
24	
25	                uart4: serial@49042000 {
26	                        compatible = "ti,omap3-uart";
27	                        reg = <0x49042000 0x400>;
28	                        interrupts = <80>;
29	                        dmas = <&sdma 81 &sdma 82>;
30	                        dma-names = "tx", "rx";
31	                        ti,hwmods = "uart4";
32	                        clock-frequency = <48000000>;
33	                };
