I have changed the way of aiming at a configurable configfs-based gadget.
After Sebastian has laid the foundation for the conversion I thought of
doing the conversion to configfs like this: 1) convert the functions to
the new function interface from Sebastian, 2) add configfs support.

Use ilog2() rather than __ffs() for calculating SEGMENT_SHIFT as ilog2() can
be worked out at compile time, whereas __ffs() must be calculated at runtime.

It seems to be getting more common recently for EHCI host controllers
to be probed after their companion UHCI or OHCI controllers. This may
be caused partly by splitting the ehci-pci driver out from ehci-hcd,
or it may be caused by changes in the way the kernel does driver
probing.
Regardless,

Hi Paul,
while continuing this patch, I stumbled upon a bit of code which doesn't
make sense to me. In dwc2_dump_global_registers is the following bit:

Hi Paul,
If you look closely at the databook, you will see that DPTXFSIZn and
DIEPTXFn are both aliases for the same register address.
Ah, right. Remebmer I don't have the databook, only the register
descriptions from the RT3052 datasheet, which are riddled with typos, so
I had assumed the
An earlier patch removed the CONFIG_USB_SUSPEND symbol but forgot to
update the Documentation files. This patch (as1676) rectifies that
omission.

Hi Dave,
I'm a little bit confused about your description for the second one.
Did you need to change the #defines names because they could conflict
with other drivers when the xHCI driver is built in? Or is there some
other point I'm missing?
Are these feature patches for 3.10, or bug fixes for
