Merge patch series "Extend usb_onboard_hub driver to support Cypress HX3 hub family"

2025-07-30T14:20:35Z

Lukasz Czechowski says: This patch series extends the usb_onboard_hub driver to allow for support of more types of onboard hub devices, and adds the Cypress HX3 hub family. First patch in the series updates the bind function, so that it no longer uses hardcoded compatible strings. Next patch simplifies the code, by removing unnecessary dm_gpio function call. Third patch updates the remove function, which allows the prevent issues with usb devices reenumeration, in case of calling "usb reset". Although the issue could still occur in case of invalid initial state of reset gpio, it is minimized with no impact on main usb_hub driver. Fourth patch extends the driver with support for multiple power supplies, the same way it is done in kernel driver. Finally, last patch provides hub data and of_match table entries for Cypress HX3 Link: https://lore.kernel.org/r/20250722-usb_onboard_hub_cypress_hx3-v4-0-91c3ee958c0e@thaumatec.com

usb: onboard-hub: Use devm API do automatically free the reset GPIO

2025-07-30T13:57:17Z

The reset GPIO is obtained during driver probing by the function devm_gpiod_get_optional, which means the GPIO will be automatically freed when the device is removed. Because of this, explicit call to free the reset GPIO in hub remove function is not needed. To support the Managed device resources, the DEVRES config must be enabled, otherwise the devres functions fall back to non-managed variants. Set the necessary dependency to DEVRES in Kconfig.

usb: dwc3-generic: Add Exynos850 support

2025-07-25T01:17:21Z

The only thing needed from DWC3 glue layer for Exynos850 is to enable USB clocks. The generic glue layer driver already does that. Add Exynos850 dwc3 compatible string to enable support for this chip. Signed-off-by: Sam Protsenko Reviewed-by: Mattijs Korpershoek Signed-off-by: Minkyu Kang

Merge patch series "list.h/treewide: get rid of no-op prefetch()"

2025-06-18T14:05:29Z

Rasmus Villemoes says: While looking through list.h, I saw that the regular list_* helpers (and one of the hlist_* ones) still contain the prefetch() that was removed in linux 14 years ago. It doesn't do anything, but makes the macros harder to read, so get rid of it, and the fallback, no-op definition that they relied on. That requires removing a few uses outside list.h as well. checkpatch warns about some whitespace issues in list.h, but as I've copied whole kerneldoc+#define blocks directly from the linux kernel, I think it's better to just accept that so that we don't introduce needless diffs. The "macro argument reuse" arguments should also be ignored, as e.g. the "member" arguments are obviously always just bare identifiers, and the "pos" arguments must be assigned to multiple times.

treewide: drop no-op prefetch() calls

2025-06-18T14:05:04Z

These all end up using the no-op prefetch() defined in linux/list.h, because the only possible real implementation is in arch/mips/include/asm/processor.h, which is behing CONFIG_CPU_HAS_PREFETCH which is nowhere defined. In order to be able to drop that fallback definition from list.h, first remove all uses. Signed-off-by: Rasmus Villemoes

usb: gadget: atmel: reliably generate disconnect by disabling controller

2025-06-16T09:56:19Z

Contrary to the datasheet, setting both DETACH and PULLD_DIS bits to 1 does not always drive the DP and DM lines to high-impedance. This prevents the host from reliably detecting a USB disconnect and subsequent reconnect. The symptom is that the first gadget command (e.g., dhcp) succeeds, while subsequent commands (e.g., nfs) fail. Disabling and re-enabling the controller entirely, instead of toggling the PULLD_DIS bit, reliably generates a disconnect event. The Linux driver works correctly because gadget_disconnect/gadget_connect are always followed by gadget_udc_start/gadget_udc_stop. In U-Boot pullup() is used solely. This behavior has been observed on the SAM9X60-Curiosity and AT91SAM9G25-EK boards and has been reported to Microchip.

usb: gadget: musb: Fix duplicate ops assignment in ti_musb_peripheral

2025-06-16T07:00:55Z

Remove duplicate .ops assignment that was overriding the correct ti_musb_gadget_ops with musb_usb_ops (host ops) in the ti_musb_peripheral driver. This was causing U-Boot crashes when trying to call the handle_interrupts operation since the wrong ops structure was being used.

spl: Rename jump_to_image_no_args()

2025-06-13T19:22:53Z

This function is currently a misnomer at times as we have cases where it passes arguments to the image. In preparation for making that be a more common case rename this function to jump_to_image(...). In order to do this, rename jump_to_image in board_init_r(...) to jumper so that we do not have a conflict.
