we don't need to enable IRQs until we have
a gadget driver loaded and ready to work,
so let's delay IRQ enable to ->udc_start()
and IRQ disable to ->udc_stop().
While at that, also move the related use of
request_irq() and free_irq().

Make the call to dwc3_event_buffers_setup()
and dwc3_event_buffers_cleanup() explicit,
so it's easier to implement PM.

We don't need the ->register_my_device flag
anymore because all UDC drivers have been
properly converted.
Let's remove every history of it.

By simply setting a flag, we can drop some

Fix the following compile warning:

Currently all UDC drivers are calling
device_register() before calling
usb_add_gadget_udc(). In order to avoid
code duplication, we can allow udc-core.c
register that device.
However that would become a really large patch,
so to cope with the meanwhile and allow us
to write bite-sized patches, we're adding
a flag which will be set by UDC driver once
it removes the code for registering the
gadget device.
Once all are converted, the new flag will
be removed.

omap5 is not going to have support for non-dt boot making the platform

Includes few minor fixes in dwc3-omap like populating the compatible
string in a correct way, extracting the utmi-mode property properly and
changing the index of get_irq since irq of core is removed from hwmod
entry.
Also updated the documentation with dwc3-omap device tree binding
information.

[ balbi@ti.com : fix a compile warning introduced by

Add 2 flags, needs_vcc and needs_reset to platform data.
If the flag is set and the regulator couldn't be found
then we bail out with -EPROBE_DEFER.
For device tree boot we depend on presensce of vcc-supply/
reset-supply properties to decide if we should bail out
with -EPROBE_DEFER or just continue in case the regulator
can't be found.
This is required for proper functionality in cases where the
regulator is needed but is probed later than the PHY device.

We expect the RESET line to be modeled as a regulator with supply
name "reset". The regulator should be modeled such that enabling
the regulator brings the PHY device out of RESET and disabling the
regulator holds the device in RESET.
They PHY will be held in RESET in .shutdown() and brought out of
RESET in .init().

If the PHY has a clock associated to it then manage the clock.
We just enable the clock in .init() and disable it in .shutdown().
Add clk_rate parameter in platform data and configure the
