Changes since v8:
- Fix build issue in s3c-hsotg on !ARM by guarding with a
"depends on ARM". Will fix by replacing use of readsl/writesl
for 3.15 and dropping the Kconfig workaround..
Changes since v7:
- Register phy provider with generic phy subsystem only after
the generic phy has been allocated and configured.
Changes since v6:
- Drop dependency on the Exynos generic phy conversion series
- Bring back original patch that converts s3c-hsotg to use the
generic phy layer with a fall back to the old usb style phy
support.
Changes since v5:
- tweak s3c-hsotg Kconfig help message to be more generic
Changes since v4:
- phy_set/get_bus_width now use an int for bus_width
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 generic phy layer 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
https://lkml.org/lkml/2013/12/5/508
(relevant portion now queued for 3.14)
