Hi,

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

Changelog:

v6: - Added r-b from Rob Herring to the OTG properties DT binding patch.

    - Corrected "smb347-charger: generic regmap caching" patch, it now
      sets the .num_reg_defaults_raw, initializing cache properly.

    - Added new patch "smb347-charger: Add missing pin control activation",
      which prevents never-enabled charging on Nexus 7.

    - The "otg-fsm: Fix hrtimer list corruption" patch of v5 was already
      applied to next, so it's not included anymore.

v5: - Replaced "Remove caching of charger state" patch with "Utilize
      generic regmap caching" after Sebastian's notice about disabled
      regmap caching.

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
      universal.

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
      time.
