d0f7a0559a usb: dwc3: Implement .glue_configure for i.MX8MP
The i.MX8MP glue needs to be configured based on a couple of DT
properties, implement .glue_configure callback to parse those DT
properties and configure the glue accordingly.

Rename the select_dr_mode callback to glue_configure, the callback is

c08db05455 usb: dwc3: dwc3-generic: check the parent nodes
The kernel devicetree has definitions for port and hub nodes as subnodes
to the USB devices. These subnodes don't contain all of the data required
to properly configure the dwc3. Check the parent nodes if the data is not
in the port/hub node.

Here's an example from the librem5 kernel dts file

&usb_dwc3_0 {
	#address-cells = <1>;
	#size-cells = <0>;
	dr_mode = "otg";
	snps,dis_u3_susphy_quirk;
	status = "okay";

	port@0 {
		reg = <0>;

		typec_hs: endpoint {
			remote-endpoint = <&usb_con_hs>;
		};
	};

	port@1 {
		reg = <1>;

		typec_ss: endpoint {
			remote-endpoint = <&usb_con_ss>;
		};
	};
};

&usb_dwc3_1 {
	dr_mode = "host";
	status = "okay";
	#address-cells = <1>;
	#size-cells = <0>;

	/* Microchip USB2642 */
	hub@1 {
		compatible = "usb424,2640";
		reg = <1>;
		#address-cells = <1>;
		#size-cells = <0>;

		mass-storage@1 {
			compatible = "usb424,4041";
			reg = <1>;

2b0b51d0be usb: dwc3: add layerscape support
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.

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.

dwc3_meson_g12a_force_mode() sets the dr-mode of the USB PHY. However
it skips setting the mode if it matches the one done during driver probe
(stored in private structure). This fails if the mode has been changed
to other value and then back to initial one. Fix this by configuring the
dr-mode always, regadless of the one set at the driver probe).

This fixes operation of USB gadget based drivers when they are initialized
for the second time.

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.

fafaa02290 usb: dwc3: Enable AutoRetry feature in the controller
By default when core sees any transaction error (CRC or overflow) it
replies with terminating retry ACK (Retry=1 and Nump == 0).

Enabling this Auto Retry feature in controller will make the core send
a non-terminanting ACK upon such transaction errors. That is, ACK TP
with Retry=1 and Nump != 0.

Doing so will give controller a chance to recover from transient error
conditions.

Reference from below Linux commit,

in the controller")

dc18413adb usb: dwc3: Add disable u2mac linestate check quirk
This patch adds a quirk to disable USB 2.0 MAC linestate check
during HS transmit. Refer the dwc3 databook, we can use it for
some special platforms if the linestate not reflect the expected
line state(J) during transmission.

When use this quirk, the controller implements a fixed 40-bit
TxEndDelay after the packet is given on UTMI and ignores the
linestate during the transmit of a token (during token-to-token
and token-to-data IPGAP).

On some rockchip platforms (e.g. rk3399), it requires to disable
the u2mac linestate check to decrease the SSPLIT token to SETUP
token inter-packet delay from 566ns to 466ns, and fix the issue
that FS/LS devices not recognized if inserted through USB 3.0 HUB.

3dc4f83970 usb: dwc3-meson-g12a: add power-on/off of the PHYs
Power on/off the PHYs to enable power to the USB ports, fixing USB support
on Khadas VIM3/VIM3L boards.

The G12A USB complex has at least 2 USB2 PHYs, but one is muxed between the
DWC2 and DWC3 controller and the other one directly connected to the DWC3
controller. The USB3+PCIe combo PHY is muxed between the DWC3 controller
and a DW-PCIE controller.
All PHYs are optional, but it's type (usb2/usb3) and position are important
to determine it's capabilities, thus they are stored in a fixed size
array and the phy-name determines it's position, it's position determining
it's type and functionnalities.
This is why we need to loop over the array to power on all the DT provided
PHYs.
