Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 6.13-rc1. Overall, a pretty slow development cycle, the majority of the work going into the debugfs interface for the thunderbolt (i.e. USB4) code, to help with debugging the myrad ways that hardware vendors get their interfaces messed up. Other than that, here's the highlights: - thunderbolt changes and additions to debugfs interfaces - lots of device tree updates for new and old hardware - UVC configfs gadget updates and new apis for features - xhci driver updates and fixes - dwc3 driver updates and fixes - typec driver updates and fixes - lots of other small updates and fixes, full details in the shortlog All of these have been in linux-next for a while with no reported problems" * tag 'usb-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (148 commits) usb: typec: tcpm: Add support for sink-bc12-completion-time-ms DT property dt-bindings: usb: maxim,max33359: add usage of sink bc12 time property dt-bindings: connector: Add time property for Sink BC12 detection completion usb: dwc3: gadget: Remove dwc3_request->needs_extra_trb usb: dwc3: gadget: Cleanup SG handling usb: dwc3: gadget: Fix looping of queued SG entries usb: dwc3: gadget: Fix checking for number of TRBs left usb: dwc3: ep0: Don't clear ep0 DWC3_EP_TRANSFER_STARTED Revert "usb: gadget: composite: fix OS descriptors w_value logic" usb: ehci-spear: fix call balance of sehci clk handling routines USB: make to_usb_device_driver() use container_of_const() USB: make to_usb_driver() use container_of_const() USB: properly lock dynamic id list when showing an id USB: make single lock for all usb dynamic id lists drivers/usb/storage: refactor min with min_t drivers/usb/serial: refactor min with min_t drivers/usb/musb: refactor min/max with min_t/max_t drivers/usb/mon: refactor min with min_t drivers/usb/misc: refactor min with min_t drivers/usb/host: refactor min/max with min_t/max_t ...

usb: dwc3: gadget: Remove dwc3_request->needs_extra_trb

2024-11-16T08:04:57Z

Now that we track TRBs base on request->num_trbs on reclaim, we don't need to save the dwc3_request->needs_extra_trb check. Remove it.

usb: dwc3: gadget: Cleanup SG handling

2024-11-16T08:04:56Z

The current logic in dwc3 driver is tracking req->num_queued_sgs and req->sg. But they can be checked base on the num_pending_sgs and num_trbs. They are redundant and can complicate the SG logic. Let's remove them. Signed-off-by: Thinh Nguyen Link: https://lore.kernel.org/r/96c7bf8f6b3e91e607d5b78ea51cb1d00c614eaf.1731545781.git.Thinh.Nguyen@synopsys.com Signed-off-by: Greg Kroah-Hartman

usb: dwc3: gadget: Fix looping of queued SG entries

2024-11-16T08:04:56Z

The dwc3_request->num_queued_sgs is decremented on completion. If a partially completed request is handled, then the dwc3_request->num_queued_sgs no longer reflects the total number of num_queued_sgs (it would be cleared). Correctly check the number of request SG entries remained to be prepare and queued. Failure to do this may cause null pointer dereference when accessing non-existent SG entry.

usb: dwc3: gadget: Fix checking for number of TRBs left

2024-11-16T08:04:56Z

The check whether the TRB ring is full or empty in dwc3_calc_trbs_left() is insufficient. It assumes there are active TRBs if there's any request in the started_list. However, that's not the case for requests with a large SG list. That is, if we have a single usb request that requires more TRBs than the total TRBs in the TRB ring, the queued TRBs will be available when all the TRBs in the ring are completed. But the request is only partially completed and remains in the started_list. With the current logic, the TRB ring is empty, but dwc3_calc_trbs_left() returns 0. Fix this by additionally checking for the request->num_trbs for active TRB count.

usb: dwc3: ep0: Don't clear ep0 DWC3_EP_TRANSFER_STARTED

2024-11-16T08:04:56Z

The driver cannot issue the End Transfer command to the SETUP transfer. Don't clear DWC3_EP_TRANSFER_STARTED flag to make sure that the driver won't send Start Transfer command again, which can cause no-resource error. For example this can occur if the host issues a reset to the device.

usb: dwc3: core: Set force_gen1 bit for all applicable SuperSpeed ports

2024-11-13T06:13:09Z

Currently if the maximum-speed is set to Super Speed for a 3.1 Gen2 capable controller, the FORCE_GEN1 bit of LLUCTL register is set only for one SuperSpeed port (or the first port) present. Modify the logic to set the FORCE_GEN1 bit for all ports if speed is being limited to Gen-1.

usb: dwc3: gadget: Add missing check for single port RAM in TxFIFO resizing logic

2024-11-13T06:12:57Z

The existing implementation of the TxFIFO resizing logic only supports scenarios where more than one port RAM is used. However, there is a need to resize the TxFIFO in USB2.0-only mode where only a single port RAM is available. This commit introduces the necessary changes to support TxFIFO resizing in such scenarios by adding a missing check for single port RAM. This fix addresses certain platform configurations where the existing TxFIFO resizing logic does not work properly due to the absence of support for single port RAM. By adding this missing check, we ensure that the TxFIFO resizing logic works correctly in all scenarios, including those with a single port RAM.

usb: dwc3: fix fault at system suspend if device was already runtime suspended

2024-11-05T12:55:06Z

If the device was already runtime suspended then during system suspend we cannot access the device registers else it will crash. Also we cannot access any registers after dwc3_core_exit() on some platforms so move the dwc3_enable_susphy() call to the top.
