This should be squashed into patch 1/4. The reason is that if just patch 1/4 is applied, then both ehci-tegra.c's legacy raw GPIO handling and phy-tegra-usb.c's new regulator-based code will attempt to gpio_request() the same GPIO, and one will fail, which will likely cause the driver to fail to probe(). -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
