Subject[PATCH v4 0/9] USB Device Controller support for BCM281xx
Changes since v3:
- Rebased on 3.13-rc3
- Move struct phy bus_width attribute back into struct phy_attrs
- Fix build issue on !GENERIC_PHY
- Update dwc2 binding to reflect optional phy properties
- Rename bcm-kona-phy.txt binding to bcm-phy.txt
- Reorder bcm kona phy includes and use bitops
- phy-names changed to "usb2-phy" to match updated s3c-hsotg
generic phy-ification series

Changes since v2:
- Rebased on 3.13-rc1
- Fix braces in phy_get_bus_width()/phy_set_bus_width()
- Drop generic phy conversion to use the same support from
the Exynos generic phy conversion series
- Modify dts support to match the "device" phy name required
in the v3 Exynos generic phy conversion
- Add s3c-hsotg phy_init/phy_exit support
- Fix typo on reg property in kona phy binding
- Replace phy driver reg struct with offset defines
- Move phy soft reset to phy driver init
- Fix dts node names to match ePAPR conventions

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, adds phy_init/phy_exit support, and supports fetching
phy bus width using the generic phy layer.

Parts 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:
- "Update Kona drivers to use clocks" v4 series
- "Add new Exynos USB 2.0 PHY driver" v4 series

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: use generic phy_init()/phy_exit() 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
