In the past, we've refrained from modelling runtime dependencies using Kconfig because in some cases (such as this) it'll include more than necessary (ChipIdea will automatically pull in the USB PHY driver irrespective of whether or not Tegra is enabled).

Please take a closer look at the patch. Tegra PHY driver is only compiled if ehci-tegra driver is compiled. So we need to decouple build dependency in order fix it. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Add Kconfig entry so that other drivers other than ehci-tegra (like ChipIdea) could add Tegra's PHY to build dependencies.
