This patch was copied from kernel commit: 67fdfda4a99ed.
Sometimes, the gadget driver we want to run has max_speed lower than
what the UDC supports. In such situations, UDC might want to make sure
we don't try to connect on speeds not supported by the gadget
driver because that will just fail.
So here introduce a new optional ->udc_set_speed() method which can be
implemented by interested UDC drivers to achieve this purpose.

avoid adding more gadget_is_xxx() handling code to usb_ep_autoconfig().

Profiling the EHCI driver shows a significant performance problem in
ehci_submit_async(). Specifically, this function keeps enabling and
disabling async schedule back and forth for every single transaction.
However, enabling/disabling the async schedule does not take effect
immediatelly, but instead may take up to 1 mS (8 uFrames) to complete.
This impacts USB storage significantly, esp. since the recent reduction
of maximum transfer size to support more USB storage devices. This in
turn results in sharp increase in the number of ehci_submit_async()
calls. Since one USB storage BBB transfer does three such calls and
the maximum transfer size is 120 kiB, the overhead is 6 mS per 120 kiB,
which is unacceptable.
However, this overhead can be removed simply by keeping the async
schedule running. Specifically, the first transfer starts the async
schedule and then each and every subsequent transfer only adds a new
QH into that schedule, waits until the QH is completed and does NOT
disable the async schedule. The async schedule is stopped only by
shutting down the controller, which must happen before moving out
of U-Boot, otherwise the controller will corrupt memory.

This fixes the issues with calculation of controller indexes in
ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't
placed next to each other, and their addresses incremented by 0x10000.
Example of USB nodes for iMX7S/D:
usbotg1: usb@30b10000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b10000 0x200>;
^^^^^^^^^^
....
usbotg2: usb@30b20000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b20000 0x200>;
^^^^^^^^^^
....
usbh: usb@30b30000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b30000 0x200>;
^^^^^^^^^^
....
Which was leading to usb enumeration issues:

The mode selection for the DWC3 is kind of obsolete. The driver does not
have to be host only or gadget only. This choice is confusing.
All the remaining callers of dwc3_uboot_init() explicitly set dr_mode
before calling the function, so none rely on a default behavior.
Remove the choice menu and keep only the USB_DWC3_GADGET option. Enable it
by default if USB_GADGET and USB_DWC3 are enabled.
It must be disabled for the evb-rk3328 as it uses DWC2 for the gadget and

Currently the host driver used by dwc3-generic is "xhci-dwc3". This is
a functional driver but it doesn't use the dwc3 core and, in particular,
it lacks some bits that may be important.
For example on the k2 platforms, it is important that the phy are properly
suspended when the USB is not used anymore. The dwc3 core also has a
partial support for quirks.
The new driver can be used as a drop-in replacement for "xhci-dwc3".
In terms of implementation, it may seem strange that 2 private structures
dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this
is simply that the xhci layer expects a struct xhci_ctrl at the beginning
of the private data and it seemed wasteful to include it also for the
peripheral case.

The EHCI iMX6 driver is only partly converted to DT probing and
still uses a tremendous amount of hard-coded addresses. Worse,
the driver uses hard-coded SoC-model-specific base addresses, which
are derived from values protected by SoC-specific macros, hence the
driver is also compiled for a specific SoC model. Even worse, the
driver depends on specific sequential indexing of the controllers,
from which it derives offsets in the PHY and ANATOP register sets.
However, when the driver is probed from DT, the indexing is not
correct. In fact, each controller has index 0. This patch derives
the index for DT probing case from the controller base addresses,
which is not the way this should be done, however it is the least
intrusive approach, favorable this close to release.
The necessary steps to convert this driver fully to DT probing are
described inside the patch, however this should be done in the next
release and depends on iMX clock driver patches.

This fixes a disconnect issue detected with fastboot command, when using
dwc2 driver.
- On u-boot side:
uboot>$ fastboot 0
- On USB host PC side, few seconds after
PC>$ fastboot reboot # Get stuck, uboot target never reboots
By enabling DEBUG_ISR logs, the bus suspend interrupt is seen before the
PC command has been issued. When the USB bus suspend occurs, there's a HACK
that disables the fastboot (composite driver). Here is the call stack
upon USB bus suspend:
- dwc2_handle_usb_suspend_intr()
- dev->driver->disconnect()
- composite_disconnect()
- reset_config()
- f->disable()
- fastboot_disable()
- usb_ep_disable(f_fb->out_ep);
- usb_ep_disable(f_fb->in_ep);
.. other disable calls.
When the resume interrupt happens, everything has been disabled, then
nothing happens. fastboot command gets stuck on HOST side.
Remove original HACK, that disconnects the composite driver upon
USB bus suspend. Implement disconnect detection instead:
- check GINTSTS OTG interrupt
- read GOTGINT register
- check GOTGINT, SesEndDet bit (e.g. session end)
This is inspired by what is implemented currently in Linux dwc2 driver.

parameter. Currently this index is assigned in the order of the driver
bindings.
Changing this behavior using the SEQ_ALIAS feature. This option assign to
the device a SEQ number based on its alias (if it exists)
To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing
naming convention: use "usb" for the name of the gadget UCLASS_DRIVER
(same as for the UCLASS_USB).
If no alias is provided, then the index falls back to the order in which

Enable DM for USB peripheral in the musb-new driver.
Also make sure that the driver can be used in the SPL.
This implies that:
* the driver must work with and without the OF_CONTROL option. That
in turn, implies that the platform data can be passed in a struct
ti_musb_platdata or be read from the dtb
* usb.o is linked in the SPL if host support is enabled
Another change is that the driver does not fail to bind (and stop the boot
process) if one of the child driver does not bind. Reporting the error is
enough. This kind of error would appear if the port is configured in the
DTS but the driver is not activated in the config.

With upcoming changes that require CONFIG_BLK, this broke
USB Mass Storage on the OMAP3 boards because if CONFIG_BLK is

available on omap3 and omap4 boards.
This patch converts the OMAP2430 MUSB glue to support DM_USB and
extracts the necessary information based on the device tree.
It's based on the ti-musb driver, but there are enough significant
differences in both the architecture and device tree entires between
am33xx and OMAP3/OMAP4, that I think it makes sense to continue to
keep the separate.
Per doc/driver-model/usb-info.txt, the USB gadget stuff hasn't
migrated to DM_USB yet, so this only supports USB Host for now.
Users wanting USB Gadgets will need to disable DM_USB and leave

While downloading or uploading megabytes of data we had thousands of
printf in console like:
transfer 0x10000 bytes done
OR
Uploading 0x1000 bytes
This because transfers are chunked and there is no way on target
side to know the overall transfer size (to print one string per
overall transfer).
All these prints on serial console do slow down significantly the
transfer and does not offer a significant information to the
developer: rkdeveloptool and Rockchip original tool do use small
chunks read/writes on big transfers. This allows on workstation
to print percentage of transfer complete and as well offers to
developer the information about: transfer is running OK.
On error, either the percentage will stop or an error will be shown
