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just outdated.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.
