Unfortunately, there's no way to actually avoid the dependencies themselves. The DT bindings and EHCI/PHY controller split are wrong, and need work on both the DT and drivers to fix. I guess I could apply all the initial DT changes to a topic branch in the Tegra tree (item 1 below), and have you merge that branch into yours, and then you could take all the USB-related patches (item 2 below) through your tree. Would that work better? The only issue with that is that we would have to defer the final DT cleanup patch until sometime after 3.10-rc1; in order to maintain bisectability, the order needs to be: (1) add new DT content required by fixed binding (2) make driver assume new binding (3) remove stale DT content no longer required by the new binding. (3) is what would have to be deferred. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
