git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 6.16-rc1. Included in here are the following: - USB offload support for audio devices. I think this takes the record for the most number of patch series (30+) over the longest period of time (2+ years) to get merged properly. Many props go to Wesley Cheng for seeing this effort through, they took a major out-of-tree hacked-up-monstrosity that was created by multiple vendors for their specific devices, got it all merged into a semi-coherent set of changes, and got all of the different major subsystems to agree on how this should be implemented both with changes to their code as well as userspace apis, AND wrangled the hardware companies into agreeing to go forward with this, despite making them all redo work they had already done in their private device trees. This feature offers major power savings on embedded devices where a USB audio stream can continue to flow while the rest of the system is sleeping, something that devices running on battery power really care about. There are still some more small tweaks left to be done here, and those patches are still out for review and arguing among the different hardware companies, but this is a major step forward and a great example of how to do upstream development well. - small number of thunderbolt fixes and updates, things seem to be slowing down here (famous last words...) - xhci refactors and reworking to try to handle some rough corner cases in some hardware implementations where things don't always work properly - typec driver updates - USB3 power management reworking and updates - Removal of some old and orphaned UDC gadget drivers that had not been used in a very long time, dropping over 11 thousand lines from the tree, always a nice thing, making up for the 12k lines added for the USB offload feature. - lots of little updates and fixes in different drivers All of these have been in linux-next for over 2 weeks, the USB offload logic has been in there for 8 weeks now, with no reported issues" * tag 'usb-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (172 commits) ALSA: usb-audio: qcom: fix USB_XHCI dependency ASoC: qdsp6: fix compile-testing without CONFIG_OF usb: misc: onboard_usb_dev: fix build warning for CONFIG_USB_ONBOARD_DEV_USB5744=n usb: typec: tipd: fix typo in TPS_STATUS_HIGH_VOLAGE_WARNING macro USB: typec: fix const issue in typec_match() USB: gadget: udc: fix const issue in gadget_match_driver() USB: gadget: fix up const issue with struct usb_function_instance USB: serial: pl2303: add new chip PL2303GC-Q20 and PL2303GT-2AB USB: serial: bus: fix const issue in usb_serial_device_match() usb: usbtmc: Fix timeout value in get_stb usb: usbtmc: Fix read_stb function and get_stb ioctl ALSA: qc_audio_offload: try to reduce address space confusion ALSA: qc_audio_offload: avoid leaking xfer_buf allocation ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variables ALSA: usb-audio: qcom: Fix an error handling path in qc_usb_audio_probe() usb: misc: onboard_usb_dev: Fix usb5744 initialization sequence dt-bindings: usb: ti,usb8041: Add binding for TI USB8044 hub controller usb: misc: onboard_usb_dev: Add support for TI TUSB8044 hub usb: gadget: lpc32xx_udc: Use USB API functions rather than constants usb: gadget: epautoconf: Use USB API functions rather than constants ...

2025-05-21ALSA: qc_audio_offload: try to reduce address space confusionArnd Bergmann
uaudio_transfer_buffer_setup() allocates a buffer for the subs->dev device, and the returned address for the buffer is a CPU local virtual address that may or may not be in the linear mapping, as well as a DMA address token that is accessible by the USB device, and this in turn may or may not correspond to the physical address. The use in the driver however assumes that these addresses are the linear map and the CPU physical address, respectively. Both are nonportable here, but in the end only the virtual address gets used by converting it to a physical address that gets mapped into a second iommu. Make this more explicit by pulling the conversion out first and warning if it is not part of the linear map, and using the actual physical address to map into the iommu in place of the dma address that may already be iommu-mapped into the usb host.

2025-05-21ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variablesArnd Bergmann
While trying to understand a bug in the audio offload code, I had to spend extra time due to unfortunate nameing of local variables and struct members. Change these to more conventional names that reflect the actual usage: - pointers to the CPU virtual addresses of a dma buffer get a _cpu suffix to disambiguate them for MMIO virtual addresses - MMIO virtual addresses that are mapped explicitly through the IOMMU get a _iova suffix consistently, rather than a mix of iova and va. - DMA addresses (dma_addr_t) that are in a device address space (linear or IOMMU) get a _dma suffix in place of the _pa suffix. - CPU physical (phys_addr_t) addresses get a _pa suffix. There is still a mixup with dma addresses here that I address in another patch. No functional changes are intended here.

2025-05-19ALSA: usb-audio: Kill timer properly at removalTakashi Iwai
The USB-audio MIDI code initializes the timer, but in a rare case, the driver might be freed without the disconnect call. This leaves the timer in an active state while the assigned object is released via snd_usbmidi_free(), which ends up with a kernel warning when the debug configuration is enabled, as spotted by fuzzer. For avoiding the problem, put timer_shutdown_sync() at snd_usbmidi_free(), so that the timer can be killed properly. While we're at it, replace the existing timer_delete_sync() at the disconnect callback with timer_shutdown_sync(), too.

2025-04-29ALSA: usb-audio: Fix duplicated name in MIDI substream namesTakashi Iwai
The MIDI substream name string is constructed from the combination of the card shortname (which is taken from USB iProduct) and the USB iJack. The problem is that some devices put the product name to the iJack field, too. For example, aplaymidi -l output on the Lanchkey MK 49 are like: % aplaymidi -l Port Client name Port name 44:0 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4 44:1 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4 where the actual iJack name can't be seen because it's truncated due to the doubly words. For resolving those situations, this patch compares the iJack string with the card shortname, and drops if both start with the same words. Then the result becomes like: % aplaymidi -l Port Client name Port name 40:0 Launchkey MK4 49 Launchkey MK4 49 MIDI In 40:1 Launchkey MK4 49 Launchkey MK4 49 DAW In A caveat is that there are some pre-defined names for certain devices in the driver code, and this workaround shouldn't be applied to them. Similarly, when the iJack isn't specified, we should skip this check, too. The patch added those checks in addition to the string comparison.

During initialisation of Focusrite USB audio interfaces, -EPROTO is sometimes returned from usb_set_interface(), which sometimes prevents the device from working: subsequent usb_set_interface() and uac_clock_source_is_valid() calls fail. This patch adds up to 5 retries in endpoint_set_interface(), with a delay starting at 5ms and doubling each time. 5 retries was chosen to allow for longer than expected waits for the interface to start responding correctly; in testing, a single 5ms delay was sufficient to fix the issue.

In order to allow userspace/applications know about USB offloading status, expose a sound kcontrol that fetches information about which sound card and PCM index the USB device is mapped to for supporting offloading. In the USB audio offloading framework, the ASoC BE DAI link is the entity responsible for registering to the SOC USB layer. It is expected for the USB SND offloading driver to add the kcontrol to the sound card associated with the USB audio device. An example output would look like: tinymix -D 1 get 'USB Offload Playback Route PCM#0' -1, -1 (range -1->255) This example signifies that there is no mapped ASoC path available for the USB SND device. tinymix -D 1 get 'USB Offload Playback Route PCM#0' 0, 0 (range -1->255) This example signifies that the offload path is available over ASoC sound card index#0 and PCM device#0. The USB offload kcontrol will be added in addition to the existing kcontrols identified by the USB SND mixer. The kcontrols used to modify the USB audio device specific parameters are still valid and expected to be used. These parameters are not mirrored to the ASoC subsystem.

2025-04-11ALSA: usb-audio: qcom: Introduce QC USB SND offloading supportWesley Cheng
Several Qualcomm SoCs have a dedicated audio DSP, which has the ability to support USB sound devices. This vendor driver will implement the required handshaking with the DSP, in order to pass along required resources that will be utilized by the DSP's USB SW. The communication channel used for this handshaking will be using the QMI protocol. Required resources include: - Allocated secondary event ring address - EP transfer ring address - Interrupter number The above information will allow for the audio DSP to execute USB transfers over the USB bus. It will also be able to support devices that have an implicit feedback and sync endpoint as well. Offloading these data transfers will allow the main/applications processor to enter lower CPU power modes, and sustain a longer duration in those modes. Audio offloading is initiated with the following sequence: 1. Userspace configures to route audio playback to USB backend and starts playback on the platform soundcard. 2. The Q6DSP AFE will communicate to the audio DSP to start the USB AFE port. 3. This results in a QMI packet with a STREAM enable command. 4. The QC audio offload driver will fetch the required resources, and pass this information as part of the QMI response to the STREAM enable command. 5. Once the QMI response is received the audio DSP will start queuing data on the USB bus. As part of step#2, the audio DSP is aware of the USB SND card and pcm device index that is being selected, and is communicated as part of the QMI request received by QC audio offload. These indices will be used to handle the stream enable QMI request.

2025-04-11ALSA: usb-audio: Allow for rediscovery of connected USB SND devicesWesley Cheng
In case of notifying SND platform drivers of connection events, some of these use cases, such as offloading, require an ASoC USB backend device to be initialized before the events can be handled. If the USB backend device has not yet been probed, this leads to missing initial USB audio device connection events. Expose an API that traverses the usb_chip array for connected devices, and to call the respective connection callback registered to the SND platform driver.

2025-04-11ALSA: usb-audio: Prevent starting of audio stream if in useWesley Cheng
With USB audio offloading, an audio session is started from the ASoC platform sound card and PCM devices. Likewise, the USB SND path is still readily available for use, in case the non-offload path is desired. In order to prevent the two entities from attempting to use the USB bus, introduce a flag that determines when either paths are in use. If a PCM device is already in use, the check will return an error to userspace notifying that the stream is currently busy. This ensures that only one path is using the USB substream.

2025-04-11ALSA: usb-audio: Save UAC sample size informationWesley Cheng
Within the UAC descriptor, there is information describing the size of a sample (bSubframeSize/bSubslotSize) and the number of relevant bits (bBitResolution). Currently, fmt_bits carries only the bit resolution, however, some offloading entities may also require the overall size of the sample. Save this information in a separate parameter, as depending on the UAC format type, the sample size can not easily be decoded from other existing parameters.

Mixer quicks for the Pioneer DJM-A9 mixer was added in 5289d00 with additional capture level values added to the common DJM array of values. This breaks the existing DJM mixers however as alsa-utils relies on enumeration of the actual mixer options based on the value array which results in error when storing state.

2025-02-18ALSA: usb-audio: Avoid dropping MIDI events at closing multiple portsTakashi Iwai
We fixed the UAF issue in USB MIDI code by canceling the pending work at closing each MIDI output device in the commit below. However, this assumed that it's the only one that is tied with the endpoint, and it resulted in unexpected data truncations when multiple devices are assigned to a single endpoint and opened simultaneously. For addressing the unexpected MIDI message drops, simply replace cancel_work_sync() with flush_work(). The drain callback should have been already invoked before the close callback, hence the port->active flag must be already cleared. So this just assures that the pending work is finished before freeing the resources.
