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 ...

thunderbolt: Replace deprecated PCI functions

2024-11-07T10:59:19Z

pcim_iomap_table() and pcim_request_regions() have been deprecated in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()") and commit d140f80f60358 ("PCI: Deprecate pcim_iomap_regions() in favor of pcim_iomap_region()"). Replace these functions with pcim_iomap_region(). Signed-off-by: Philipp Stanner Signed-off-by: Mika Westerberg

thunderbolt: Fix connection issue with Pluggable UD-4VPD dock

2024-11-05T14:29:47Z

Rick reported that his Pluggable USB4 dock does not work anymore after upgrading to v6.10 kernel. It looks like commit c6ca1ac9f472 ("thunderbolt: Increase sideband access polling delay") makes the device router enumeration happen later than what might be expected by the dock (although there is no such limit in the USB4 spec) which probably makes it assume there is something wrong with the high-speed link and reset it. After the link is reset the same issue happens again and again. For this reason lower the sideband access delay from 5ms to 1ms. This seems to work fine according to Rick's testing.

thunderbolt: debugfs: Implement asymmetric lane margining

2024-11-01T05:55:38Z

Add support for the RX2 receiver which is used as the third receiver in asymmetric links. This requires expanding the results array for the additional third data word of the hardware margining results. Signed-off-by: Aapo Vienamo Signed-off-by: Mika Westerberg

thunderbolt: debugfs: Don't hardcode margining results size

2024-11-01T05:55:38Z

Use ARRAY_SIZE() when available or pass in the array size derived from it. This is in preparation for adding another result data word for supporting Gen 4 asymmetric links with an additional lane. Signed-off-by: Aapo Vienamo Signed-off-by: Mika Westerberg

thunderbolt: debugfs: Refactor hardware margining result parsing

2024-11-01T05:55:38Z

Make the result parsing and formatting code less repetitive in preparation for adding another result for Gen 4 asymmetric link support. Signed-off-by: Aapo Vienamo Signed-off-by: Mika Westerberg

thunderbolt: debugfs: Replace margining lane numbers with an enum

2024-11-01T05:55:38Z

Replace the raw values and macros with an enum and use it consistently. No functional changes. Signed-off-by: Aapo Vienamo Signed-off-by: Mika Westerberg

thunderbolt: debugfs: Replace "both lanes" with "all lanes"

2024-11-01T05:55:38Z

With USB4 Gen 4, the link can be configured into an asymmetric mode, where there are three receivers and only one transmitter. The USB4 specification also uses the "all lanes" nomenclature instead of "both lanes". Signed-off-by: Aapo Vienamo Signed-off-by: Mika Westerberg
