be5c0608b8 usb: Enforce DM_USB migration for USB_HOST devices.
As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:

- Ensuring that all host controller options (other than the very legacy
  old MUSB ones) now select USB_HOST.  USB_HOST now enforces DM_USB and
  OF_CONTROL.
  - Remove other parts of Kconfig logic that had platforms pick DM_USB.
  - To keep Kconfig happy, have some select statements test for USB_HOST
    as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
  host or gadget roles.  For the various HCD options that have platform
  glue options, group them together and update dependencies in some
  cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
  it, disable it.

46eddbc58f usb: dwc3: add Amlogic GXL & GXL DWC3 Glue
The USB support was initialy done with a set of PHYs and dwc3-of-simple
because the architecture of the USB complex was not understood correctly
at the time (and proper documentation was missing...).

But with the G12A family, the USB complex was correctly understood and
implemented correctly.

This adds a proper driver for the glue, based on the G12A one, but with
enough changes to require a different driver in U-Boot.

3e6ab7327f usb: dwc3: Kconfig: get rid of obsolete mode selection
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.

adb049abf7 usb: dwc3: Add Meson G12A USB Glue
Adds support for Amlogic G12A USB Control Glue HW.

The Amlogic G12A SoC Family embeds 2 USB Controllers :
- a DWC3 IP configured as Host for USB2 and USB3
- a DWC2 IP configured as Peripheral USB2 Only

A glue connects these both controllers to 2 USB2 PHYs, and optionnally
to an USB3+PCIE Combo PHY shared with the PCIE controller.

The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including
routing of the OTG PHY between the DWC3 and DWC2 controllers, and
setups the on-chip OTG mode selection for this PHY.

This driver sets the OTG capable port as Host mode by default,
the switch to Device mode is to be done in a separate patch.

446e3a205b dwc3-generic: Handle the PHYs, the clocks and the reset lines
This make the driver more generic. At this point this driver can replace
the dwc3-of-simple implementation.
Make the description in the Kconfig more generic too.

49d674547c usb: dwc3: Add generic DWC3 glue logic driver
By enabling BLK by default this is the next driver which needs to get
support for DM_USB. Adding generic DWC3 glue logic which only
parse nodes and read device mode. Based on it probe proper
host/peripheral DWC3 drivers for it.

6ea247d137 usb: dwc3: fix Kconfig dependency to accept host driver in drivers/usb/dwc3
We see the choice of USB_DWC3_HOST / _GADGET in drivers/usb/dwc3/Kconfig,
but we can not choose USB_DWC3_HOST unless USB_GADGET is defined.
This is strange.

Loosen the "depends on" and also move "select USB_GADGET_DUALSPEED" to
the correct place.

3457bbaf22 usb: gadget: Move CONFIG_USB_GADGET_DUALSPEED to Kconfig
Move CONFIG_USB_GADGET_DUALSPEED option to Kconfig and
make all UDC controllers select USB_GADGET_DUALSPEED:
  - add next options to Kconfig selecting USB_GADGET_DUALSPEED:
    - USB_GADGET_ATMEL_USBA
    - USB_GADGET_DWC2_OTG
    - USB_DWC3
    - CI_UDC
  - make USB_MUSB_GADGET select USB_GADGET_DUALSPEED

While at it, make some related fixes:
  - remove DUALSPEED from configs that don't enable gadget support:
    - kwb.h
    - tseries.h
  - add missing USB_GADGET option to next configs:
    - novena_defconfig
    - pcm051_rev*_defconfig
    - xfi3_defconfig
