Subject: [PATCH 0/5] USB Device Controller support for BCM281xx

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.

Parts 1-2 allows s3c-hsotg to build on non-Samsung platforms and
adds support for a configurable UTMI PHY width. s3c-hsotg is extended
to also support the dwc2 binding as that binding should describe the
hardware independently of there being two different drivers (dwc2 in
staging and s3c-hsotg) for the same device.

Parts 3-4 add a PHY control driver for the Broadcom USB control block
as well as a PHY driver that calls the exported API from the control
driver. This approach is borrowed directly from the phy-omap-control.c
driver.

Patch 5 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.

Matt Porter (5):
  usb: gadget: s3c-hsotg: enable build for other platforms
  usb: gadget: s3c-hsotg: support configurable UTMI PHY width
  usb: phy: add Broadcom Kona USB control driver
  usb: phy: add Broadcom Kona USB PHY driver
  ARM: dts: add usb udc support to bcm281xx
