2012-11-21usb: remove use of __devinitdataBill Pemberton
CONFIG_HOTPLUG is going away as an option so __devinitdata is no longer needed.

2012-11-14usb: spear-ehci/ohci: Use devm_*() routinesViresh Kumar
This patch frees SPEAr ehci/ohci drivers from tension of freeing resources :) devm_* derivatives of multiple routines are used while allocating resources, which would be freed automatically by kernel.

2012-11-14usb: spear-ehci/ohci: Do clk_get using dev-idAmardeep Rai
We used to get clk using con-id, but now we have device struct available for these devices as they are probed using DT. And so must get clk using dev-id.

2012-10-31USB: EHCI: remove ehci_port_power() routineAlan Stern
This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.

2012-07-09EHCI: centralize controller initializationAlan Stern
This patch (as1564c) converts the EHCI platform drivers to use the central ehci_setup() routine for generic controller initialization rather than each having its own idiosyncratic approach. The major point of difficulty lies in ehci-pci's many vendor- and device-specific workarounds. Some of them have to be applied before calling ehci_setup() and some after, which necessitates a fair amount of code motion. The other platform drivers require much smaller changes. One point not addressed by the patch is whether ports should be powered on or off following initialization. The different drivers appear to handle this pretty much at random. In fact it shouldn't matter, because the hub driver turns on power to all ports when it binds to the root hub. Straightening that out will be left for another day.

2012-07-09EHCI: centralize controller suspend/resumeAlan Stern
This patch (as1563) removes a lot of duplicated code by moving the EHCI controller suspend/resume routines into the core driver, where the various platform drivers can invoke them as needed. Not only does this simplify these platform drivers, this also makes it easier for other platform drivers to add suspend/resume support in the future. Note: The patch does not touch the ehci-fsl.c file, because its approach to suspend and resume is so different from all the others. It will have to be handled specially by its maintainer.

2012-04-18USB: ehci: ohci: Add clk_{un}prepare() supportViresh Kumar
clk_{un}prepare is mandatory for platforms using common clock framework. Since these drivers are used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for them.

2011-05-03USB: EHCI: Support controllers with big endian capability regsJan Andersson
The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.
