So we believed that we can't directly pickup all Linux kernel dwc3
patches
and merge to U-Boot.
If you were to sync the driver from Linux to U-Boot, then the same
sequence as Linux uses would be automatically used too, right ?
Sorry for the abysmal delay in my reply.
Are we saying that we shall port/use Linux driver in U-Boot and abandon
the existing USB host driver in U-Boot?
No, the existing driver in U-Boot is a port of the Linux driver, it is just
outdated. I am saying, just pick the missing patches from Linux and add them
to U-Boot, so the two drivers are in sync.
We do not see a DWC3 host driver under usb host folder in Linux
https://elixir.bootlin.com/linux/latest/source/drivers/usb/host. Would you mind
to tell us which DWC3 host driver we should use in usb host folder? Then, we
can pick up the missing patches
drivers/usb/dwc3
Same as u-boot
