usb: musb: dsps: use platform_get_irq_byname_optional() for vbus IRQ

2025-09-06T13:22:20+00:00

The vbus IRQ is optional, so no error message should be printed if it is not available. Signed-off-by: Matthias Schiffer Signed-off-by: Alexander Stein Link: https://lore.kernel.org/r/20250825124901.2190539-1-alexander.stein@ew.tq-group.com Signed-off-by: Greg Kroah-Hartman

usb: musb: omap2430: clean up probe error handling

2025-07-25T08:50:44+00:00

Using numbered error labels is discouraged (e.g. as it requires renumbering them when adding a new intermediate error path). Rename the error labels after what they do. While at it, drop the redundant platform allocation failure dev_err() as the error would already have been logged by the allocator.

usb: musb: omap2430: fix device leak at unbind

2025-07-25T08:50:43+00:00

Make sure to drop the reference to the control device taken by of_find_device_by_node() during probe when the driver is unbound.

usb: musb: omap2430: enable compile testing

2025-07-25T08:50:39+00:00

Nothing seems to prevent the driver from being compile tested on non-OMAP platforms so enable it to provide wider build coverage. Signed-off-by: Johan Hovold Link: https://lore.kernel.org/r/20250724092104.21317-1-johan@kernel.org Signed-off-by: Greg Kroah-Hartman

usb: musb: fix gadget state on disconnect

2025-07-07T08:58:15+00:00

When unplugging the USB cable or disconnecting a gadget in usb peripheral mode with echo "" > /sys/kernel/config/usb_gadget//UDC, /sys/class/udc/musb-hdrc.0/state does not change from USB_STATE_CONFIGURED. Testing on dwc2/3 shows they both update the state to USB_STATE_NOTATTACHED. Add calls to usb_gadget_set_state in musb_g_disconnect and musb_gadget_stop to fix both cases.

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37+00:00

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

usb: musb: cppi41: Switch to use hrtimer_setup()

2025-02-18T10:19:02+00:00

hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism. Patch was created by using Coccinelle.
