[U-Boot] [PATCH 0/3] rockchip: rv1108: support USB OTG and Host ports on evb-rv1108

[William Wu]

This patch support USB OTG and Host ports on evb-rv1108 board. With this patch,
we can use fastboot over USB and mount USB mass storage on OTG and Host ports.

[U-Boot] [PATCH 1/3] configs: rockchip: add USB configs for evb-rv1108 board

[William Wu]

This patch adds USB configs to support the USB OTG port(consist
of DWC2 controller) and the USB Host port(consist of EHCI and OHCI
controllers) on evb-rv1108 board, and also support fastboot over
USB and USB mass storage.

These USB init things have been bothering me for a while. Do you think
this could be changed into a driver that you could probe with
device_probe()? Then much of the code in here would not be needed and
it might be easier to tidy it up when we have proper driver-model
support for USB device mode.

Yes,  on rockchip platforms, it did most of the same USB init things in 
different board special drivers.
I think may be we can try to optimize the code in two different ways.

Method1.
1. Move the USB init things from board_usb_init(), just simply call 
dwc2_udc_probe().
2. Create a new USB init  function in drivers/usb/gadget/dwc2_udc_otg.c，
      and call it in dwc2_udc_probe().
3. Use fdt (Flat Device Tree manipulation )  to parse the dts, and get 
the regs_phy, regs_otg and so on.

Method2.
Just like your  suggestion， use driver-model method to probe with 
device_probe,
actually, I don't know much about the driver-model, as far as I know, we 
may need
to do the following work:
1. Create a new uclass id for usb udc, and declare a new uclass_driver 
with UCLASS_DRIVER,
     and also need to create a  new U-boot driver for dwc2 controller 
with U_BOOT_DRIVER.
2. How to call device_probe()? Maybe it's better to create a new driver 
(like drivers/usb/host/usb-uclass.c)
     in drivers/usb/gadget to match different usb gadget controllers, 
and wrap the device_probe()
     to a new function (like udc_pre_probe()), and then different udc 
driver can call it,
     e.g.
     dwc2_udc_probe() --> udc_pre_probe() --> device_probe()

In summary, method1 is easily to be done, but method2 is more generic.

I hope I haven't misunderstood your proposal, and hope to get your reply.
Thank you!

suggest is reasonable, since something has to decide that the USB
device mode should be started.
