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	- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
8	  request selector for this UART controller.
9	
10	Optional properties:
11	- nvidia,enable-modem-interrupt: Enable modem interrupts. Should be enable
12			only if all 8 lines of UART controller are pinmuxed.

14	Example:
15	
16	serial@70006000 {
17		compatible = "nvidia,tegra30-hsuart", "nvidia,tegra20-hsuart";
18		reg = <0x70006000 0x40>;
19		reg-shift = <2>;
20		interrupts = <0 36 0x04>;
