1	NVIDIA Tegra20/Tegra30 high speed (DMA based) UART controller driver.
2	
3	Required properties:
4	- compatible : should be "nvidia,tegra30-hsuart", "nvidia,tegra20-hsuart".
5	- reg: Should contain UART controller registers location and length.
6	- interrupts: Should contain UART controller interrupts.
7	- clocks: Must contain one entry, for the module clock.
8	  See ../clocks/clock-bindings.txt for details.
9	- resets : Must contain an entry for each entry in reset-names.
10	  See ../reset/reset.txt for details.
11	- reset-names : Must include the following entries:
12	  - serial
13	- dmas : Must contain an entry for each entry in clock-names.
14	  See ../dma/dma.txt for details.
15	- dma-names : Must include the following entries:
16	  - rx
17	  - tx
18	
19	Optional properties:
20	- nvidia,enable-modem-interrupt: Enable modem interrupts. Should be enable
21			only if all 8 lines of UART controller are pinmuxed.
22	
23	Example:
24	
25	serial@70006000 {
26		compatible = "nvidia,tegra30-hsuart", "nvidia,tegra20-hsuart";
27		reg = <0x70006000 0x40>;
28		reg-shift = <2>;
29		interrupts = <0 36 0x04>;
30		nvidia,enable-modem-interrupt;
31		clocks = <&tegra_car 6>;
32		resets = <&tegra_car 6>;
33		reset-names = "serial";
34		dmas = <&apbdma 8>, <&apbdma 8>;
35		dma-names = "rx", "tx";
36		status = "disabled";
37	};
