3799c40189 [PATCH] USB: S3C2410: use clk_enable() to ensure 48MHz to OHCI core
Get the "usb-bus" clock and ensure it is enabled
when the OHCI core is in use.

It seems that a few bootloaders do not enable the
UPLL at startup, which stops the OHCI core having
a 48MHz bus clock. The improvements to the clock
framework for the s3c24xx now allow the USB PLL
to be started and stopped when being used.

a8d3584a2d [ARM] Remove clk_use()/clk_unuse()
It seems that clk_use() and clk_unuse() are additional complexity
which isn't required anymore.  Remove them from the clock framework
to avoid the additional confusion which they cause, and update all
ARM machine types except for OMAP.

3ae5eaec1d [DRIVER MODEL] Convert platform drivers to use struct platform_driver
This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for

0c0382e32d [PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspend
This patch (as580) is perhaps the only result from the long discussion I
had with David about his changes to the root-hub suspend/resume code.  It
renames the hub_suspend and hub_resume methods in struct usb_hcd to
bus_suspend and bus_resume.  These are more descriptive names, since the
methods really do suspend or resume an entire USB bus, and less likely to
be confused with the hub_suspend and hub_resume routines in hub.c.

It also takes David's advice about removing the layer of bus glue, where
those methods are called.  And it implements a related change that David
made to the other HCDs but forgot to put into dummy_hcd.

9293677af3 [PATCH] all HCDs provide root hub suspend/resume methods
This cleans up a small recent FIXME, ensuring that all the HCDs provide
root hub suspend/resume methods.  It also wraps the calls to those root
suspend routines just like on the PCI "USB_SUSPEND not defined" cases,
so non-PCI bus glue won't be as tempted to behave very differently.

Several of the SOC based OHCI drivers forgot to list those methods;
the patch also adds those missing declarations.

8ad7fe16df [PATCH] remove some USB_SUSPEND dependencies
This simplifies some of the PM-related #ifdeffing by recognizing
that USB_SUSPEND depends on PM.  Also, OHCI drivers were often
testing for USB_SUSPEND when they should have tested just PM.

It's pointless to include mach-types.h if you're not going to use
anything from it.  These references were removed as a result of:
