This series adds USB OTG mode support to the NVIDIA Tegra USB PHY driver,
SMB347 charger driver and Nexus 7 tablet.


v4: - Added r-b from Rob Herring.

    - Added unevaluatedProperties into SMB binding for VBUS regulator,
      which was Requested by Rob Herring.

    - Added cell to nvidia,pmc phandle instead of explicit h/w ID
      property. Requested by Rob Herring.

    - Added stack trace to commit message and ack from Peter Chen to
      OTG FSM patch.

v3: - Further improved interrupt handling in the PHY driver by removing
      assumption that interrupt is enabled by the CI driver at the time
      of set_wakeup() invocation, which makes this function a bit more

v2: - The PHY's interrupt is now enabled from PHY's set_wakeup() callback.
      It prevents getting a spurious interrupt during the CI driver probe
