Name each ehci driver uniquely.
This remove the warning printed at each arm boot :
module_register: cannot register simplebus/ehci from kernel; already loaded from kernel
Similarly as other extres pseudo-drivers, implement phy by using kobj model.
This detaches it from provider device, so single device driver can export
multiple different phys. Additionally, this allows phy to be subclassed to
more specialized drivers, like is USB OTG phy, or PCIe phy with hot-plug
capability.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
It doesn't seems to be needed anymore and this make ehci working again
on the Pine64.
Thanks to jmcneill@ for the help.
Tested on: Pine64 (A64), OrangePi One (H3), BananapiM2 (A31s)
If we cannot get a phy, do not detach the driver, some boards have phy
always enabled and not exposed.
While here do not release the clocks if we fails as we release them
in a10_ehci_detach.
Tested-on: OrangePi-One
When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.

Previously the USB PHY driver would enable all regulators at attach time.
This prevented boards from booting when powered by the USB OTG port, as
it didn't take VBUS presence into consideration.
Clocks, GPIO, UART, SD card / eMMC, USB, watchdog, and ethernet are
supported. Note that the A83T contains two clusters of four Cortex-A7
CPUs, and only CPUs in first cluster are started for now.
Tested on a Sinovoip Banana Pi BPI-M3.
adds a lock to ensure only a single device is accessing the hardware. A
reference count is added to only enable when we start to use the clock,
and to disable after we have finished needing the clock.
This was extracted from a larger review to add OHCI support to the
Allwinner SoCs.

* Use the Linux compat string
* Use EARLY_DRIVER_MODULE to attach at the right time
* Add a generic A10 kernel config file
* A20 now use generic_timer
* Add two new dts files for Olimex boards
* Update our custom DTS file for A10 and A20 to use the same compatible

to check the status property in their probe routines.
Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352. Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.
Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.
