2022-07-08usb: mtu3: check capability of usb3 dual roleChunfeng Yun
It is capable of supporting usb3 dual role if there is at least one usb3 port for device and xhci controller, we can check it from the controller's capability, so no need the property "mediatek,usb3-drd" anymore, but I find the property is not decribed in dt-binding. Meanwhile, also take into account if the u3 port is disabled when the u3 phy is shared with pcie.

2022-07-08usb: mtu3: add feature to disable device's usb3 portChunfeng Yun
We may want to disable device's usb3 port when the combo phy is switched from usb3 mode to pcie mode for some projects. Meanwhile rename member @is_u3_ip to @u3_capable to avoid misleading, due to the member's value may be changed when disable usb3 port, but the controller is still a usb3 IP which also tells us how to manage the fifo.

2022-07-08USB: gadget: udc: tracing: Do not open code __string() with __dynamic_array()Steven Rostedt (Google)
The event classes udc_log_ep and udc_log_req both declare: __dynamic_array(char, name, UDC_TRACE_STR_MAX) Which will reserve UDC_TRACE_STR_MAX bytes on the ring buffer for the event to write in name. It then uses snprintf() to write into that space. Assuming that the string being copied is nul terminated, it is better to just use the __string() helper. That way only the size of the string is saved into the ring buffer and not the max size (yes, the entire UDC_TRACE_STR_MAX is used in the trace event, and anything not used is just junk in the ring buffer). Worse, there's also meta data saved into the event that denotes where the string is stored in the event and also saves its size, which is always going to be UDC_TRACE_STR_MAX. Convert both to use the __string() and __assign_str() helpers that are for this kind of use case.

2022-07-07ARM: sa1100/assabet: move dmabounce hack to ohci driverArnd Bergmann
The sa1111 platform is one of the two remaining users of the old Arm specific "dmabounce" code, which is an earlier implementation of the generic swiotlb. Linus Walleij submitted a patch that removes dmabounce support from the ixp4xx, and I had a look at the other user, which is the sa1111 companion chip. Looking at how dmabounce is used, I could narrow it down to one driver one three machines: - dmabounce is only initialized on assabet/neponset, jornada720 and badge4, which are the platforms that have an sa1111 and support DMA on it. - All three of these suffer from "erratum #7" that requires only doing DMA to half the memory sections based on one of the address lines, in addition, the neponset also can't DMA to the RAM that is connected to sa1111 itself. - the pxa lubbock machine also has sa1111, but does not support DMA on it and does not set dmabounce. - only the OHCI and audio devices on sa1111 support DMA, but as there is no audio driver for this hardware, only OHCI remains. In the OHCI code, I noticed that two other platforms already have a local bounce buffer support in the form of the "local_mem" allocator. Specifically, TMIO and SM501 use this on a few other ARM boards with 16KB or 128KB of local SRAM that can be accessed from the OHCI and from the CPU. While this is not the same problem as on sa1111, I could not find a reason why we can't re-use the existing implementation but replace the physical SRAM address mapping with a locally allocated DMA buffer. There are two main downsides: - rather than using a dynamically sized pool, this buffer needs to be allocated at probe time using a fixed size. Without having any idea of what it should be, I picked a size of 64KB, which is between what the other two OHCI front-ends use in their SRAM. If anyone has a better idea what that size is reasonable, this can be trivially changed. - Previously, only USB transfers to unaddressable memory needed to go through the bounce buffer, now all of them do, which may impact runtime performance for USB endpoints that do a lot of transfers. On the upside, the local_mem support uses write-combining buffers, which should be a bit faster for transfers to the device compared to normal uncached coherent memory as used in dmabounce.

2022-06-29usb: dwc3: gadget: Fix event pending checkThinh Nguyen
The DWC3_EVENT_PENDING flag is used to protect against invalid call to top-half interrupt handler, which can occur when there's a delay in software detection of the interrupt line deassertion. However, the clearing of this flag was done prior to unmasking the interrupt line, creating opportunity where the top-half handler can come. This breaks the serialization and creates a race between the top-half and bottom-half handler, resulting in losing synchronization between the controller and the driver when processing events. To fix this, make sure the clearing of the DWC3_EVENT_PENDING is done at the end of the bottom-half handler.

2022-06-24USB: gadget: Fix double-free bug in raw_gadget driverAlan Stern
Re-reading a recently merged fix to the raw_gadget driver showed that it inadvertently introduced a double-free bug in a failure pathway. If raw_ioctl_init() encounters an error after the driver ID number has been allocated, it deallocates the ID number before returning. But when dev_free() runs later on, it will then try to deallocate the ID number a second time. Closely related to this issue is another error in the recent fix: The ID number is stored in the raw_dev structure before the code checks to see whether the structure has already been initialized, in which case the new ID number would overwrite the earlier value. The solution to both bugs is to keep the new ID number in a local variable, and store it in the raw_dev structure only after the check for prior initialization. No errors can occur after that point, so the double-free will never happen.

2022-06-22USB: serial: pl2303: add support for more HXN (G) typesJohan Hovold
Add support for further HXN (G) type devices (GT variant, GL variant, GS variant and GR) and document the bcdDevice mapping. Note that the TA and TB types use the same bcdDevice as some GT and GE variants, respectively, but that the HX status request can be used to determine which is which. Also note that we currently do not distinguish between the various HXN (G) types in the driver but that this may change eventually (e.g. when adding GPIO support).

2022-06-21staging: octeon-usb: move driver out of stagingArtur Bujdoso
The Octeon usb driver has been in staging for a long time and used in Ubiquiti routers for a while now. It's been built and then tested on real hardware with several usb devices and it is proven to be stable and ready to be moved to its proper place in the kernel tree. Move it to drivers/usb/host and adjust its Makefile, Kconfig and defconfig dependencies. Many thanks to the developers who made it happen.
