-and additions :
-
-Required properties :
- - compatible : For Tegra20, must contain "nvidia,tegra20-ehci".
-   For Tegra30, must contain "nvidia,tegra30-ehci".  Otherwise, must contain
-   "nvidia,<chip>-ehci" plus at least one of the above, where <chip> is
-   tegra114, tegra124, tegra132, or tegra210.
- - nvidia,phy : phandle of the PHY that the controller is connected to.
- - clocks : Must contain one entry, for the module clock.
-   See ../clocks/clock-bindings.txt for details.
- - resets : Must contain an entry for each entry in reset-names.
-   See ../reset/reset.txt for details.
- - reset-names : Must include the following entries:
