[PATCH v2 0/9] USB Device Controller support for BCM281xx

Changes since v1:
	- Convert USB phy driver to generic phy subsystem
	- Add phy bus width apis
	- Drop dwc2 phy bus width DT property in favor of querying the
	  phy provider for bus width
	- Add generic phy/clock properties to dwc2 DT binding
	- Add generic phy subsystem support to s3c-hsotg with the
	  existing usb phy and pdata phy methods as a fallback
	- Split bindings out to separate patches to match the latest
	  DT binding review guidelines

This series adds USB Device Controller support for the Broadcom
BCM281xx family of parts. BCM281xx contains a DWC2 OTG block and
s3c-hsotg is used to support UDC operation.

Part 1 adds phy bus width support to the generic phy subsystem

Parts 2-6 allows s3c-hsotg to build on non-Samsung platforms, supports
the dwc2 binding, and enables generic phy support to support fetching
of the phy bus width.

Part 7-8 add a generic phy binding and driver for the BCM Kona USB PHY.

Part 9 adds the DT nodes to enable UDC support on both BCM281xx boards
in the kernel.

This series depends on the "Update Kona drivers to use clocks" series
(https://lkml.org/lkml/2013/10/3/645). The dependencies noted for that
series are already queued for 3.13. It also depends on the generic PHY
subsystem which has also been queued for 3.13.
