usb: gadget: Mark udc_disconnect as static

2026-03-03T08:09:43+00:00

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

dm: usb: Deal with USB keyboard persisting across tests

2024-09-18T19:01:00+00:00

Clear any USB-keyboard devices before running a unit test, to avoid
using a stale udevice pointer in stdio. Add a long comment to explain
this situation and why this solution seems best, at least for now.

usb: Drop old non-DM code

2024-09-18T19:00:59+00:00

The driver model deadline for USB was in 2019, so drop the old USB
keyboard code, to avoid needing to deal with the extra code path.

Drop the unnecessary #ifdef around USB_KBD_BOOT_REPORT_SIZE while we
are here.

usb: xhci: Set up endpoints for the first 2 interfaces

2024-04-05T01:25:14+00:00

The xhci driver currently only does the necessary initialization for
endpoints found in the first interface descriptor. Apple USB keyboards
(released 2021) use the second interface descriptor for the HID keyboard
boot protocol. To allow USB drivers to use endpoints from other
interface descriptors the xhci driver needs to ensure these endpoints
are initialized as well.
Use USB_MAX_ACTIVE_INTERFACES to control how many interface descriptors
are considered during endpoint initialisation.
For now define it to 2 as that is sufficient for supporting the Apple
keyboards.

usb: Return -ENOENT when no devices are found

2023-08-09T15:31:11+00:00

When USB finds no devices it currently returns -EPERM which bootstd does
not understand. This causes other bootdevs of the same priority to be
skipped.

Fix this by returning the correct error code.

usb: Tidy up the usb_start flag

2023-05-13T13:52:32+00:00

This should be declared in a header file so that type-checking works
correctly.

Add a single declaration to usb.h and remove the others.

usb: eth: Remove non-DM_ETH code

2022-12-07T21:04:17+00:00

As DM_ETH is required for all network drivers, it's now safe to remove
the non-DM_ETH support code fro usb_ether itself.

usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mn

2022-02-10T23:03:48+00:00

The imx8mm and imx8mn appear compatible with imx7d-usb
flags in the OTG driver.  If the dr_mode is defined as
host or peripheral, the device appears to operate correctly,
however the auto host/peripheral detection results in an error.

The solution isn't just adding checks for imx8mm and imx8mn to
the check for imx7, because the USB clock needs to be running
to read from the USBNC_PHY_STATUS_OFFSET register or it will hang.

Marek requested that I not enable the clocks in ehci_usb_of_to_plat,
so I modified that function to return an unknown state if the
device tree does not explicitly state whether it is a host
or a peripheral.

When the driver probes, it looks to see if it's in the unknown
state, and only then will it read the register to auto-detect.
