2012-04-26ARM: tegra: add USB ULPI PHY reset GPIO to device treeStephen Warren1-0/+3
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.

2012-03-08arm: tegra: dts: Support host/device selection and legacy modeSimon Glass1-0/+13
Some USB ports can support host and device operation. We add the dr_mode property (as found in Freescale) for this. One USB port has a 'legacy mode', left over from the days of pre-Tegra chips. I don't believe this is actually used, except that we must know to turn this off in the driver.

2011-12-08arm/dt: add basic usb nodes to tegra device treesOlof Johansson1-0/+13
For now they are a minimal binding. It needs to be amended with vendor-specific settings for phy setup and link tuning, etc. v2: Added bindings specification and phy_type properties Signed-off-by: Olof Johansson <olof@lixom.net> Acked-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Stephen Warren <swarren@nvidia.com>
