With the last external callers of udc_disconnect long removed, mark this
function as static now and remove it from headers.

usb: gadget: dwc2: Move dr_mode check from of_to_plat() to bind()

2026-01-30T08:01:42+00:00

Rockchip RK3288 and RK3506 contain two DWC2 USB controllers, typically
one controller use dr_mode=otg and the other one use dr_mode=host.

With USB_GADGET_DWC2_OTG, DM_USB_GADGET and USB_DWC2 enabled this result
in the dwc2-udc-otg driver binding to both controllers, however only one
will probe due to use of dr_mode=host on the other one.

After the commit 6668b8e7cc68 ("dm: core: Support multiple drivers with
same compatibles") it is possible to bind one controller to the
dwc2-udc-otg driver and the other one to the dwc2_usb driver.

Move the dr_mode check from of_to_plat() to bind() to allow dm core to
bind the dwc2 host driver to dr_mode=host controllers.

Merge branch 'qcom-main' of https://source.denx.de/u-boot/custodians/u-boot-snapdragon

2026-01-16T21:14:37+00:00

We have been getting a lot more patches from Qualcomm engineers, largely
focusing on IoT, router, and automotive platforms (those with QCS, IPQ,
and SA prefixes specifically).

Quite a variety of changes here:
- Watchdog overflow fix
- Hardcoded fastboot buffer addresses for a few board (hoppefully
  temporary until fastboot is updated to read $fastboot_addr_r)
- Enable memory protection (MMU_MGPROT) for ARCH_SNAPDRAGON
- pinctrl support for the QCS615 soc
- various USB/phy fixes including phy config for msm8996/qcs615
- mmc and i2c clock configuration fixes
- significant fixes for rpmh and regulator drivers
- added config fragment for pixel devices
- sa8775p clock fixes
- support for "flattened" dwc3 DT that recently landed upstream for
  sc7280 (qcs6490) and a few other platforms

usb: gadget: Kconfig: Correct Qualcomm config name used

2026-01-14T15:17:48+00:00

Correct ARCH_QCOM to ARCH_SNAPDRAGON as ARCH_QCOM is outdated/unused
config. Using ARCH_QCOM was causing USB fastboot mode to fail.

usb: ci_udc: Check ci_ep->desc before use

2026-01-09T08:24:39+00:00

There are two places where ci_ep->desc could be accessed despite it is
not valid at that moment. Either the endpoint has not been enabled yet
or it has been disabled meanwhile (The ethernet gadged behaves this way
at least.). That results in dereferencing a null pointer.

Moreover, the patch gets rid of possible outstanding requests if the
endpoint's state changes to disabled.

usb: gadget: Tighten CI_UDC dependencies

2025-11-12T21:13:03+00:00

This driver cannot build when DM_USB_GADGET is enabled as both options
control building of files that use the same global namespace and
functionality. In this case make CI_UDC depend on DM_USB_GADGET being
disabled as non-DM support is the legacy choice.
