UPSTREAM: usb: dwc3: Fix UTMI/UTMIW phy interface initialization

DWC3 support phy interfaces like 8/16-bit UTMI+. phy interface
initialization code would handle them properly along with UNKNOWN
type by default if none of the user/board doesn't need to use the
phy interfaces at all.

The current code is masking the 8/16-bit UTMI+ interface bits globally
which indeed effect the UNKNOWN cases, therefore it effects the platforms
which are not using phy interfaces at all.

So, handle the phy masking bits accordingly on respective interface
type cases.

UPSTREAM: usb: dwc3: Add phy interface for dwc3_uboot

U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
call dwc3_uboot_init in core.

The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.

So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.

This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.

This change used Linux phy.h enum list, to make proper code
compatibility.

Add a new function that read quirk and configuration information from the

The function is adapted from the function dwc3_get_properties() in the

UPSTREAM: usb: dwc3-generic: add a new host driver that uses the dwc3 core

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.

UPSTREAM: 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.
