usb: fixes for v5.2-rc5
A single fix to take into account the PHY width during initialization of dwc2 driver. This change allows deviceTree to pass PHY width if necessary.

xhci: detect USB 3.2 capable host controllers correctly
USB 3.2 capability in a host can be detected from the xHCI Supported Protocol Capability major and minor revision fields. If major is 0x3 and minor 0x20 then the host is USB 3.2 capable. For USB 3.2 capable hosts set the root hub lane count to 2. The Major Revision and Minor Revision fields contain a BCD version number. The value of the Major Revision field is JJh and the value of the Minor Revision field is MNh for version JJ.M.N, where JJ = major revision number, M - minor version number, N = sub-minor version number, e.g. version 3.1 is represented with a value of 0310h. Also fix the extra whitespace printed out when announcing regular SuperSpeed hosts.

usb: xhci: Don't try to recover an endpoint if port is in error state.
A USB3 device needs to be reset and re-enumarated if the port it connects to goes to a error state, with link state inactive. There is no use in trying to recover failed transactions by resetting endpoints at this stage. Tests show that in rare cases, after multiple endpoint resets of a roothub port the whole host controller might stop completely. Several retries to recover from transaction error can happen as it can take a long time before the hub thread discovers the USB3 port error and inactive link. We can't reliably detect the port error from slot or endpoint context due to a limitation in xhci, see xhci specs section 4.8.3: "There are several cases where the EP State field in the Output Endpoint Context may not reflect the current state of an endpoint" and "Software should maintain an accurate value for EP State, by tracking it with an internal variable that is driven by Events and Doorbell accesses" Same appears to be true for slot state. set a flag to the corresponding slot if a USB3 roothub port link goes inactive to prevent both queueing new URBs and resetting endpoints.

usb: dwc2: Use generic PHY width in params setup
Setting params.phy_utmi_width in dwc2_lowlevel_hw_init() is pointless since
it's value will be overwritten by dwc2_init_params().
This change make sure to take in account the generic PHY width information
during paraminitialisation, done in dwc2_set_param_phy_utmi_width().
By doing so, the phy_utmi_width params can still be overrided by
devicetree specific params and will also be checked against hardware
capabilities.

usb: chipidea: udc: workaround for endpoint conflict issue
An endpoint conflict occurs when the USB is working in device mode during an isochronous communication. When the endpointA IN direction is an isochronous IN endpoint, and the host sends an IN token to endpointA on another device, then the OUT transaction may be missed regardless the OUT endpoint number. Generally, this occurs when the device is connected to the host through a hub and other devices are connected to the same hub. The affected OUT endpoint can be either control, bulk, isochronous, or an interrupt endpoint. After the OUT endpoint is primed, if an IN token to the same endpoint number on another device is received, then the OUT endpoint may be unprimed (cannot be detected by software), which causes this endpoint to no longer respond to the host OUT token, and thus, no corresponding interrupt occurs. There is no good workaround for this issue, the only thing the software could do is numbering isochronous IN from the highest endpoint since we have observed most of device number endpoint from the lowest.

xhci: Convert xhci_handshake() to use readl_poll_timeout_atomic()
Xhci_handshake() implements the algorithm already captured by readl_poll_timeout_atomic(). Convert the former to use the latter to avoid repetition. Turned out this patch also fixes a bug on the AMD Stoneyridge platform where usleep(1) sometimes takes over 10ms. This means a 5 second timeout can easily take over 15 seconds which will trigger the watchdog and reboot the system.

xhci: Fix immediate data transfer if buffer is already DMA mapped
xhci immediate data transfer (IDT) support in 5.2-rc1 caused regression
on various Samsung Exynos boards with ASIX USB 2.0 ethernet dongle.
If the transfer buffer in the URB is already DMA mapped then IDT should
not be used. urb->transfer_dma will already contain a valid dma address,
and there is no guarantee the data in urb->transfer_buffer is valid.
The IDT support patch used urb->transfer_dma as a temporary storage,
copying data from urb->transfer_buffer into it.
Issue was solved by preventing IDT if transfer buffer is already dma
mapped, and by not using urb->transfer_dma as temporary storage.

usb: xhci: Fix a potential null pointer dereference in xhci_debugfs_create_endpoint()
In xhci_debugfs_create_slot(), kzalloc() can fail and dev->debugfs_private will be NULL. In xhci_debugfs_create_endpoint(), dev->debugfs_private is used without any null-pointer check, and can cause a null pointer dereference. To fix this bug, a null-pointer check is added in xhci_debugfs_create_endpoint(). This bug is found by a runtime fuzzing tool named FIZZER written by us.

xhci: update bounce buffer with correct sg num
This change fixes a data corruption issue occurred on USB hard disk for
the case that bounce buffer is used during transferring data.
While updating data between sg list and bounce buffer, current
implementation passes mapped sg number (urb->num_mapped_sgs) to
sg_pcopy_from_buffer() and sg_pcopy_to_buffer(). This causes data
not get copied if target buffer is located in the elements after
mapped sg elements. This change passes sg number for full list to
fix issue.
Besides, for copying data from bounce buffer, calling dma_unmap_single()
on the bounce buffer before copying data to sg list can avoid cache issue.

USB: Fix slab-out-of-bounds write in usb_get_bos_descriptor
The syzkaller USB fuzzer found a slab-out-of-bounds write bug in the USB core, caused by a failure to check the actual size of a BOS descriptor. This patch adds a check to make sure the descriptor is at least as large as it is supposed to be, so that the code doesn't inadvertently access memory beyond the end of the allocated region when assigning to dev->bos->desc->bNumDeviceCaps later on.

treewide: prefix header search paths with $(srctree)/
Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit

ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms.
Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to multiplatform enabled.
- Cleanups of Davinci
This tag also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release.

USB: serial: f81232: clear overrun flag
The F81232 will report data and LSR with bulk like following format: bulk-in data: [LSR(1Byte)+DATA(1Byte)][LSR(1Byte)+DATA(1Byte)]... LSR will auto clear frame/parity/break error flag when reading by H/W, but overrrun will only cleared when reading LSR. So this patch add a worker to read LSR when overrun and flush the worker on close() & suspend().
