[PATCHv7 0/5] SB: ohci-da8xx: Add device tree support

[Axel Haslam]

When booting using device tree, we can not make use of
platform callbacks to handle vbus and over current gpios.

This series allows the ohci-da8xx driver to use a regulator
instead of the platform callbacks to control vbus and adds
the device tree bindings to be able to probe using DT.

Once all users of the platform callbacks will be converted to
use a regulator, we will be able to remove platform data completely.

**DEPENDENCY**:
These patches depend on a regulator patch that is
merged into linux-next, but not yet on usb-next:

regulator: core: Add new API to poll for error conditions
https://lkml.org/lkml/2016/11/3/191


Changes from v6->v7
* remove print on over current event as the usb core already does it (David)
* fix ocic mask for regulator event (David)
* spelling fix and tested-by on first patch.
* skip error message on probe defer from regulator (David)

Changes from v5->v6
* Fix regulator over current flag check (David)
* Spelling fixes and code cleanups (David)
* add Ack for device tree binding

Changes from v4->v5
* Append the Device tree patches to v4.
* Submit only the first part of the series (no dependencies).
this can be applied and merged through the usb tree.

Changes from v3->v4
* separate the series into smaller series for driver and arch/arm code,
  to ease review and merging to different trees.

Changes form v2->v3
* drop patches that have been integrated to arch/arm
* drop regulator patches which will be integrated through regulator tree
* use of the accepted regulator API to get over current status
* better patch separation with the use of wrappers

Changes from v1->v2
* Rebased and added patch to make ohci a separate driver
* Use a regulator instead of handling Gpios (David Lechner)
* Add an over current mode to regulator framework
* Fixed regulator is able to register for and over current irq
* Added patch by Alexandre to remove build warnings
* Moved global variables into private hcd structure.
