Device tree entries for the three EHCI controllers on Tegra114.
Enables the the third controller (USB host) on Dalmore.

I would have done the board patch separately from the SoC one.

At the same address as the previous node?

Hm, there must be some mistake: two similar register ranges.

+ compatible = "nvidia,tegra30-ehci", "usb-ehci";

+ phy3: usb-phy@7d008000 {

Again at the same address as previous node?

+ compatible = "nvidia,tegra30-usb-phy";
+ reg = <0x7d008000 0x4000 0x7d000000 0x4000>;

Second range conflicts with previous nodes.

WBR, Sergei
