Recent versions of the core, can suspend and resume
the PHYs automatically, so we don't need to fiddle
with dwc3's Global PHY registers at all.

On versions prior to 1.94a this patch will mean
that we will never ask dwc3 to suspend the PHY.

This is an acceptable behavior or such old versions
of the core, specially considering that the only
chip known to have a version prior to 1.94a was
OMAP5 ES1.0 and that's not supported in mainline
kernel, because it was just a test spin of OMAP5.

This patch adapts the dwc3 to use the device tree helper
"of_usb_get_dr_mode" for the mode of operation of the dwc3 instance
being probed.

This is a Linux-only driver which makes use
of GPL-only symbols. It makes no sense to
maintain Dual BSD/GPL licensing for this driver.

Considering that the amount of work to use this
driver in any different operating system would likely
be as large as developing the driver from scratch and
considering that we depend on GPL-only symbols, we
will switch over to a GPL v2-only license.

That driver hasn't been really maintained for
a long time. It doesn't compile in any way, it
includes non-existent headers, has no users,
and is just plain broken.

The person who used to work with that driver
has publicly stated that he has no plans to
touch that driver again and is ok with removal[1].

Due to these factors, imx_udc is now removed from
the tree, if someone really believe it needs to
be kept, please fix the bugs in that driver.

Glue layers are starting to have separate

is starting to use extcon framework which

In order to make it clear the proper dependencies,
we are now allowing glue layers to be selectable

without messing with the core IP driver.

The core code creates a controller and immediately after that it calls

This check is hardly required and alas is wrong. 'c' might be NULL but

Since no other DMA implementation is doing that and musb-core does not

  The other two patches are the big ugly ones that redo how the driver
  allocates objects and reserves them and makes things all work

  which hits a lockdep warning and the sleep while atomic warning before
