In the existing implementation, multiple requests queued up on an
endpoint are subject to getting evicted without transmission.
For both control and bulk endpoints, their respective logic found in
usba_control_irq()/usba_ep_irq() guarantees that TX FIFO is empty before
data is sent out, and that request_complete() gets called once the
transaction has been finished. At this point however, if any additional
requests are found on the endpoint queue, they will be processed by
submit_next_request(), which makes no checks against the above
conditions, trashing data on a busy FIFO and neglecting completion
handlers.
Fix the above issues by removing the calls to submit_next_request(),
and thus forcing the pending requests to be processed on the next pass
of the respective endpoint logic. While at it, remove a DBG message, as
that branch becomes part of regular flow.
This restores mass storage mode operation on Microchip ATSAMA5D27 SoC.

EHCI is usually used with companion controller (like OHCI) as companion
controller. This information on the companion is missing currently in
companion drivers.
So, if the usb-uclass isn't aware, it may scan busses in any order: OHCI
first, then EHCI.
This is seen on STM32MP1 where DT probing makes the probe order to occur
by increasing address (OHCI address < EHCI address).
When a low speed or full-speed device is plugged in, it's not detected as
EHCI should first detect it, and give ownership (handover) to OHCI.
Current situation on STM32MP1 (with a low speed device plugged-in)
STM32MP> usb start

Bus usb@5800c000: USB OHCI 1.0
Bus usb@5800d000: USB EHCI 1.00

scanning bus usb@5800d000 for devices... 1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
The "companion" property in the device tree allow to retrieve companion
controller information, from the EHCI node. This allow marking the
companion driver as such.
With this patch (same low speed device plugged in):
STM32MP> usb start
starting USB...

Move the ethernet gadget driver registration and removal from ethernet
bind and unbind callbacks into driver DM probe and remove callbacks.
This way, when the driver is bound, which is triggered deliberately
using 'bind' command, the USB ethernet gadget driver is instantiated
and bound to the matching UDC. In reverse, when the driver is unbound,
which is again triggered deliberately using 'unbind' command, the USB
ethernet gadget driver instance is removed.
Effectively, this now behaves like running either 'ums' or 'dfu' or
any other commands utilizing USB gadget functionality.
This also drops use of usb_gadget_release() and moves the use of
usb_gadget_initialize() into usb_ether_init() used only by legacy
platforms that do not use 'bind' command properly yet. Those have

At the moment we use "select" in each Allwinner SoC's Kconfig section to
include the USB PHY driver in the build. This means it cannot be disabled
via Kconfig, although USB is not really a strictly required core
functionality, and a particular board might not even include USB ports.
Rework the Kconfig part by removing the "select" lines for each SoC's
section, and instead letting it default to "y" in the PHY driver section
itself. We use "depends on !" to exclude the few SoCs we don't support
(yet). The Allwinner V3s does not enable USB (PHY) support at the moment,
even though it should work: let the PHY default to "n" to keep the
current behaviour.
Also the MUSB USB driver directly calls some functions from the PHY
driver, so let the former depend on the PHY driver.
