Subject: [PATCH v6 0/5]  Add EHCI and OHCI drivers for STi SoC's

Hi,

I believe all feedback has been incorporated, and this series has also been rebased on
3.17-rc3.

It 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 v5:
 - Remove shared header file and duplicate private structure to help readability
   and keep driver self contained, based on Arnd feedback.
 - Rebased on 3.17-rc3

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
