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.

Multiple dwc3 probe calls try to allocate no_op_xceive platform
device. Having static IDs for these will throw sysfs error -EEXIST.
Changing these static platform device IDs to AUTO to enable

Add an API in the omap glue layer to write to the mailbox register which
can be used by comparator driver(twl). To pass the detection of the attached
device (signified by VBUS, ID) to the dwc3 core, dwc3 core has to write
to the mailbox regiter.

We will be adding support for transceivers on
dwc3 driver but not all boards have controllable
transceivers.
For those which don't provide controllable transceivers
we will register nop transceivers.
Note that once OMAP's transceiver drivers reach mainline,
this glue layer will change accordingly.

if we ever have an omap with multiple instances of
the DWC3 IP, we need unique names for them. In order
to achieve that, let's use the dwc3_get/put_device_id()

We can have three modules here: dwc3.ko, dwc3-omap.ko and dwc3-pci.ko.
The later have already ids-aliases for probing and is fine. The omap
module has alias for DT but lacks alias for the "native"
platform_device. Maybe we should get rid of it and stick to the DT name?
Both glue modules create a new device for which the dwc3.ko module is
responsible and that one lacks the platform alias.

There's no need to add driver_data for something
we can fetch from HW.
This also makes our id_table unnecessary - at least

The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.
Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.
The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.
More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.
While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.
