Hi,

As part of the RESEND I've rebased this series on top of 3.17-rc3. I believe all
feedback has been addressed.

The series was re-worked from v2 onwards to split out the ehci and ohci parts
into their own drivers / devices like most other ARM platforms based on
feedback from Arnd Bergmann (see here http://www.spinics.net/lists/linux-usb/msg111124.html.

The ehci-platform & ohci-platform have been used as a basis for this in case we
wish to merge the drivers again in the future.

Changes since v4:
- Ensure suspend / resume callbacks are wrapped in #ifdef CONFIG_PM_SLEEP as otherwise we
will get linker 'unused function' warnings when this option is disabled.
- Only declare and reference pm_ops struct if CONFIG_PM_SLEEP is enabled, this saves a few bytes

Changes since v3:
- Make reset / power, clocks etc non optional dt options to simplify code
- Get rid of non DT boot code left over from *hci-platform drivers
- Remove DMA mask code
- Remove pre_setup func ptr and configure ahb2st bus convertor in ehci_platform_reset
- Unabstract and remove usb-st-common.c
- Have one kconfig which enables both ehci-st & ohci-st drivers

Changes since v2:
- Based on Arnd Berghman feedback, split out into 2 devices / drivers
- Base drivers oh ehci-platform.c & ohci-platform.c with required extensions
to allow possible re-merge in the furture.

Changes since v1:
- Correct s/OCHI/OHCI/ spelling
- Improve kconfig help message
- Various formating / spelling nits identified by Lee Jones
- Make driver depend on OF & remove node checks in code
- Use devm_ioremap_resource
- Remove unnecessary header files
