[U-Boot] [PATCH 3/4] usb: dwc3: add support for 16 bit UTMI+ interface

[Kever Yang]

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.

[U-Boot] [PATCH 4/4] config: rk3399: add support for dwc3 gadget

[Kever Yang]

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.

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.

Thanks,
- Kever

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.

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.

I think you are already talking about how this might move to device

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.

Thanks,
- Kever

I mean adding CONFIG_USB_DWC3_USB2PHY_16BIT instead of parsing DT .

I think the former would be easier, yes ?

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.

Implementing (a) is fine, while (b) would be excellent.
