    ARM: tegra: add USB ULPI PHY reset GPIO to device tree · aa607ebf
    Stephen Warren authored
    ULPI PHYs have a reset signal, and different boards use a different GPIO
    for this task. Add a property to device tree to represent this.
    
    I'm not sure if adding this property to the EHCI controller node is
    entirely correct; perhaps eventually we should have explicit separate
    nodes for the various PHYs. However, we don't have that right now, so this
    binding seems like a reasonable choice.
