Subject[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
( 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.

Matt Porter (9):
phy: add phy_get_bus_width()/phy_set_bus_width() calls
staging: dwc2: update DT binding to add generic clock/phy properties
usb: gadget: s3c-hsotg: enable build for other platforms
usb: gadget: s3c-hsotg: add snps,dwc2 compatible string
usb: gadget: s3c-hsotg: enable generic phy support
usb: gadget: s3c-hsotg: get phy bus width from phy subsystem
phy: add Broadcom Kona USB2 PHY DT binding
phy: add Broadcom Kona USB2 PHY driver
ARM: dts: add usb udc support to bcm281xx
