Hi,
This is a follow up on my last two patchsets [1] [2], where the latter only
with a small change in addition to posting all the patches.
The DWC3 USB driver was forked from the Linux kernel v3.19-rc1 eleven years
ago by commit 85d5e7075f33 ("usb: dwc3: add dwc3 folder from linux kernel
to u-boot"). Since then, not many kernel changes have been ported back into
U-Boot.
This series synchronizes the DWC3 core with Linux v6.16. To provide
a clear audit trail and maintain bisectability, I have structured the
series as follows:
1. Restore to Baseline: The first commit reverts U-Boot-specific changes
to drivers/usb/dwc3 to return the directory to a clean v3.19-rc1 state.
2. Milestone Imports: A sequence of 50+ commits follows, each performing
a "snapshot" import of the drivers/usb/dwc3 directory for every major
kernel version (v3.19 through v6.16).
3. U-Boot Adaptation: The final commits (based on Jerome's original work [3])
re-introduce the necessary glue code, XHCI/UDC updates, and build fixes
required for U-Boot integration.
Note that this is compile-tested only. The CI pipeline on source.denx.de
was used as an OK/NOK indicator [4].
These patches are also available at [5].
Thanks,
Jens

v3 -> v4:
- Restored obj-$(CONFIG_$(PHASE_)USB_DWC3_AM62) for dwc3-am62.o
RFC v2 -> v3:
- Rebased on v2026.07-rc3
- Configured out a few prints in drivers/usb/gadget/udc/udc-core.c
to make it build for am335x_evm_defconfig
- Applied provided tags in [1]
- Published as a branch
RFC v1 -> RFC v2:
- Split the v1 ("usb: dwc3: re-import from kernel v6.16-rc7") into ("usb:
dwc3: restore to original v3.19-rc1 kernel import"), ("usb: dwc3: import
from kernel v3.19)..("usb: dwc3: import from kernel v6.16-rc7")

I do see all of them in my mailbox and u-boot list is cc'ed. Haven;t
tried b4 though
They are available now.
