The dwc3 controller is using 8 bit UTMI+ interface for USB2.0 PHY, add one MACRO CONFIG_USB_DWC3_USB2PHY_16BIT to support 16 bit UTMI+ interface on some SoCs like Rockchip rk3399.

This should be configured from either DT or Kconfig option.
This setting in kernel is from DT, but we do not use DT for gadget mode in U-Boot. How about we add a quirk for it like u2phy_utmi_width_quirk in both dwc3_device and dwc3 struct for device mode?
For Host mode, we can get from DT and also need a quirk to store it.

Surely, if you can get this info from DT for host mode, you can also get it from DT for gadget mode, yes ?

Surely, if you can get this info from DT for host mode, you can also get it from DT for gadget mode, yes ?
No, for gadget mode, the controller is init by board_usb_init() called from cmd like fastboot, there is no uclass driver for a udc driver and no one parse the DT currently.
You can see my patch "[PATCH 2/4] board: evb-rk3399: add api to support dwc3 gadget" for how it initialized.

This should be configured from either DT or Kconfig option.
This setting in kernel is from DT, but we do not use DT for gadget mode in U-Boot. How about we add a quirk for it like u2phy_utmi_width_quirk in both dwc3_device and dwc3 struct for device mode?
For Host mode, we can get from DT and also need a quirk to store it.

No, for gadget mode, the controller is init by board_usb_init() called from cmd like fastboot, there is no uclass driver for a udc driver and no one parse the DT currently.
Which doesn't imply you cannot parse the DT though, correct ? I would _much_ rather see you parsing DT over adding new ad-hoc compile time config option.
You can see my patch "[PATCH 2/4] board: evb-rk3399: add api to support dwc3 gadget" for how it initialized.

Sorry, I don't understand what do you mean by "adding new ad-hoc compile time config option".
Do you mean (a) add fdt_get_property() to parse DT only for this setting? Or (b) implement a new driver for gadget mode with driver-model support which bind the device during DT instead of board_usb_init()?
The case (a) would be easy while case (b) suppose to be a big update. The source of driver for dwc3 gadget is in drivers/usb/dwc3 and the source of driver for dwc3 host is in drivers/usb/host, we will have to merge this two driver into one in case (b) bacause they are using the some controller which means the same dts node.
I would like to see these two driver merge into one like what kernel do, but I think it need someone who very familiar with both dwc3 host and gadget to port the driver from kernel.

I mean adding CONFIG_USB_DWC3_USB2PHY_16BIT instead of parsing DT .

I believe drivers/usb/dwc3 is pulled from Linux, so this is the only codebase which we should ever use to add host mode to.
I would like to see these two driver merge into one like what kernel do, but I think it need someone who very familiar with both dwc3 host and gadget to port the driver from kernel.
Implementing (a) is fine, while (b) would be excellent.

To support fastboot, we need to enable the controller first. rk3399 is using dwc3 as usb device controller, this patch enable the configs for dwc3 gadget.
