Merge tag 'usb-6.7-rc1' of 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 6.7-rc1. Nothing really major in here, just lots of constant development for new hardware. Included in here are: - Thunderbolt (i.e. USB4) fixes for reported issues and support for new hardware types and devices - USB typec additions of new drivers and cleanups for some existing ones - xhci cleanups and expanded tracing support and some platform specific updates - USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi, and i2c drivers for that type of device (all acked by the respective subsystem maintainers.) - lots of USB gadget driver updates and cleanups - new USB dwc3 platforms supported, as well as other dwc3 fixes and cleanups - USB chipidea driver updates - other smaller driver cleanups and additions, full details in the shortlog All of these have been in the linux-next tree for a while with no reported problems" * tag 'usb-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (167 commits) usb: gadget: uvc: Add missing initialization of ssp config descriptor usb: storage: set 1.50 as the lower bcdDevice for older "Super Top" compatibility usb: raw-gadget: report suspend, resume, reset, and disconnect events usb: raw-gadget: don't disable device if usb_ep_queue fails usb: raw-gadget: properly handle interrupted requests usb:cdnsp: remove TRB_FLUSH_ENDPOINT command usb: gadget: aspeed_udc: Convert to platform remove callback returning void dt-bindings: usb: fsa4480: Add compatible for OCP96011 usb: typec: fsa4480: Add support to swap SBU orientation dt-bindings: usb: fsa4480: Add data-lanes property to endpoint usb: typec: tcpm: Fix NULL pointer dereference in tcpm_pd_svdm() Revert "dt-bindings: usb: Add bindings for multiport properties on DWC3 controller" Revert "dt-bindings: usb: qcom,dwc3: Add bindings for SC8280 Multiport" thunderbolt: Fix one kernel-doc comment usb: gadget: f_ncm: Always set current gadget in ncm_bind() usb: core: Remove duplicated check in usb_hub_create_port_device usb: typec: tcpm: Add additional checks for contaminant arm64: dts: rockchip: rk3588s: Add USB3 host controller usb: dwc3: add optional PHY interface clocks dt-bindings: usb: add rk3588 compatible to rockchip,dwc3 ...

@@ -93,44 +93,18 @@ DMA address space of the device. However, most buffers passed to your
driver can safely be used with such DMA mapping. (See the first section
of Documentation/core-api/dma-api-howto.rst, titled "What memory is DMA-able?")
-- When you're using scatterlists, you can map everything at once. On some
- systems, this kicks in an IOMMU and turns the scatterlists into single
- DMA transactions::
+- When you have the scatterlists which have been mapped for the USB controller,
+ you could use the new ``usb_sg_*()`` calls, which would turn scatterlist
+ into URBs::
- int usb_buffer_map_sg (struct usb_device *dev, unsigned pipe,
- struct scatterlist *sg, int nents);
+ int usb_sg_init(struct usb_sg_request *io, struct usb_device *dev,
+ unsigned pipe, unsigned period, struct scatterlist *sg,
+ int nents, size_t length, gfp_t mem_flags);
- void usb_buffer_dmasync_sg (struct usb_device *dev, unsigned pipe,
- struct scatterlist *sg, int n_hw_ents);
+ void usb_sg_wait(struct usb_sg_request *io);
- void usb_buffer_unmap_sg (struct usb_device *dev, unsigned pipe,
- struct scatterlist *sg, int n_hw_ents);
+ void usb_sg_cancel(struct usb_sg_request *io);
- It's probably easier to use the new ``usb_sg_*()`` calls, which do the DMA
- mapping and apply other tweaks to make scatterlist i/o be fast.
-
-- Some drivers may prefer to work with the model that they're mapping large
- buffers, synchronizing their safe re-use. (If there's no re-use, then let
- usbcore do the map/unmap.) Large periodic transfers make good examples
- here, since it's cheaper to just synchronize the buffer than to unmap it
- each time an urb completes and then re-map it on during resubmission.
-
- These calls all work with initialized urbs: ``urb->dev``, ``urb->pipe``,
- ``urb->transfer_buffer``, and ``urb->transfer_buffer_length`` must all be
- valid when these calls are used (``urb->setup_packet`` must be valid too
- if urb is a control request)::
-
- struct urb *usb_buffer_map (struct urb *urb);
-
- void usb_buffer_dmasync (struct urb *urb);
-
- void usb_buffer_unmap (struct urb *urb);
-
- The calls manage ``urb->transfer_dma`` for you, and set
- ``URB_NO_TRANSFER_DMA_MAP`` so that usbcore won't map or unmap the buffer.
- They cannot be used for setup_packet buffers in control requests.
-
-Note that several of those interfaces are currently commented out, since
-they don't have current users. See the source code. Other than the dmasync
-calls (where the underlying DMA primitives have changed), most of them can
-easily be commented back in if you want to use them.
+ When the USB controller doesn't support DMA, the ``usb_sg_init()`` would try
+ to submit URBs in PIO way as long as the page in scatterlists is not in the
+ Highmem, which could be very rare in modern architectures.
