The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

A few of the platform specific DWC3 host glue drivers cannot build
without access to some platform specific header files. Express those
requirements in Kconfig as well.

Imply means you can turn off the option and expect things to work
- "it's a good idea to have X enabled" is when to use imply
- "you must have X for Y to work" is when to use select
Use "select" here.

Make sure the PHY subsystem is activated for the uniphier DWC3 glue

dwc3-uniphier depends on xhci-dwc3 framework, however, it is preferable
to use dwc3-generic.
This driver calls the exported dwc3-generic functions and redefine
the SoC-dependent operations to fit dwc3-generic.

Suppress warnings when building the SPL without USB_DWC3_GENERIC

Add support for the proper dwc3 device tree binding support as specified
in the offical device tree spec.
Initially, add support for the LS1028A support. Other SoCs should be
easy to add by just adding the corresponding compatible string.
Unfortunately, the device trees of all other layerscape SoCs are not
converted and uses a wrong compatible string only known in u-boot.
To maintain backwards compatibility with current u-boot device trees,
add the generic "fsl,layerscape-dwc3" compatible string.
OTG mode is not supported yet. The dr_mode in the devicetree will either
have to be set to peripheral or host.

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.

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.

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.

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.

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.

- 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
