This uclass is intended for devices that do not need any features from the
uclass, including binding children.
This will typically be used by devices that are used to bind child devices
but do not use dm_scan_fdt_dev() to do it. That is for example the case of
several USB wrappers that have 2 child devices (1 for device and 1 for
host) but bind only one at a any given time.

dwc3-generic has been broken since MISC uclass has been modified to scan DT

Fixing it by a using the no-op uclass.

This allow the phy to enter idle and then suspend.
the K2 platforms require the PHY to be suspended before the USB domain
clock can be turned off.

Factor code for re-usability.
This is another step toward adding host support.

To: u-boot
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.

There is no need to fail if the maximum speed is not specified.
If the speed is not specified, do the same as linux and assume super speed.

Add a new function that read quirk and configuration information from the
DT. The goal is to allow platforms using their own version of DWC3 driver
to migrate to the generic DWC3 driver.
The function is adapted from the function dwc3_get_properties() in the
linux dwc3 driver introduced in commit c5ac6116db35d.

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
DWC3 for the host.

There is no proper power domain support for the keystone platforms.
However we need to turn off the USB domains before jumping to linux or it
fail to boot (observed with k2e and k2l platforms).
This can be done in the PHY driver as it is dedicated only to the keystone
platforms and matches the required on/off sequence.

KEYSTONE_USB_PHY is now required for proper USB operations.
XHCI_DWC3 can be disabled as the xhci-dwc3 is not used anymore
USB_DWC3_GADGET can also be removed, it is now selected automatically.

As the PHY driver now handles the transitions of USB power domain, we
must add this information in the node of each PHY.
Also, the phy are expected in the "phys" property, not "usb-phys".
Also add the aliases for the USB ports on boards with more than a single
port.

Subject: [U-Boot] [PATCH v2 00/18] Improvement for the DWC3 USB generic driver and fixes for the K2 platforms
The K2 platforms have shown boot issues after switching to the DWC3 generic driver. Those are due to the fact that the USB domains are not turned off before booting linux and the phy were not properly initialized. Fixing it by improving the DWC3-generic driver and handling the USB power domain in the PHY driver.
At the same time this series introduce a new uclass (UCLASS_NOP) to replace usage of UCLASS_MISC in the USB wrapper because the MISC class now automatically binds all the child devices.
Improvements to the DWC3 generic driver are:
- Fix it by switching to UCLASS_NOP
- core: read quirks properties from DT and apply the fixes.
- add a new host driver that uses the DWC3 core (more generic than
xhci-dwc3). This should enable most platforms to drop their own version
of the xhci-driver to use the generic one instead.
This series also removes the now unused xhci-zynqmp driver and tries to better manage the Kconfig options related to DWC3 gadget/host mode selection.
This has been tested with K2 and DRA7 platforms (host and device modes).
Travis build: https://travis-ci.org/jjhiblot/u-boot/builds/515282720
Changes in v2:
- Add a test for the NOP uclass
- Update commit logs
- Select USB_GADGET_DUALSPEED if USB_DWC3_GADGET is selected

Could you also provide proper Tested-by tag to this patch set? In that
way it would automatically be added to patchwork, and your tag would be
applied to the patches.
Thanks in advance.

I cant provide Tested-by as I tested this with one out of tree patch(https://marc.info/?l=u-boot&m=155409909828219). If it goes in, then
I can provide Tested-by.
