Add a new driver for supporting Xilinx platforms. This driver is used for some sequence of operations required for Xilinx USB controllers. This driver is also used to choose between PIPE clock coming from SerDes and the Suspend Clock.

2021-03-23USB: ehci: drop workaround for forced irq threadingJohan Hovold1-10/+3
Force-threaded interrupt handlers used to run with interrupts enabled, something which could lead to deadlocks in case a threaded handler shared a lock with code running in hard interrupt context (e.g. timer callbacks) and did not explicitly disable interrupts. Since commit 81e2073c175b ("genirq: Disable interrupts for force threaded handlers") interrupt handlers always run with interrupts disabled on non-RT so that drivers no longer need to do handle forced threading ("threadirqs"). Drop the now obsolete workaround added by commit a1227f3c1030 ("usb: ehci: fix deadlock when threadirqs option is used").

It's not possible to do anything about the cyclic dependency of the Kconfig options, but USB_EHCI_TEGRA is now a deprecated option that isn't used by defconfigs and USB_GADGET is wanted on Tegra by default, hence it's okay to have a bit clunky workaround for it.

2021-03-17usb: dwc3: gadget: Prevent EP queuing while stopping transfersWesley Cheng1-6/+5
In the situations where the DWC3 gadget stops active transfers, once calling the dwc3_gadget_giveback(), there is a chance where a function driver can queue a new USB request in between the time where the dwc3 lock has been released and re-aquired. This occurs after we've already issued an ENDXFER command. When the stop active transfers continues to remove USB requests from all dep lists, the newly added request will also be removed, while controller still has an active TRB for it. This can lead to the controller accessing an unmapped memory address. Fix this by ensuring parameters to prevent EP queuing are set before calling the stop active transfers API.

2021-03-17usb-storage: Add quirk to defeat Kindle's automatic unloadAlan Stern2-0/+19
Matthias reports that the Amazon Kindle automatically removes its emulated media if it doesn't receive another SCSI command within about one second after a SYNCHRONIZE CACHE. It does so even when the host has sent a PREVENT MEDIUM REMOVAL command. The reason for this behavior isn't clear, although it's not hard to make some guesses. At any rate, the results can be unexpected for anyone who tries to access the Kindle in an unusual fashion, and in theory they can lead to data loss (for example, if one file is closed and synchronized while other files are still in the middle of being written). To avoid such problems, this patch creates a new usb-storage quirks flag telling the driver always to issue a REQUEST SENSE following a SYNCHRONIZE CACHE command, and adds an unusual_devs entry for the Kindle with the flag set. This is sufficient to prevent the Kindle from doing its automatic unload, without interfering with proper operation. Another possible way to deal with this would be to increase the frequency of TEST UNIT READY polling that the kernel normally carries out for removable-media storage devices. However that would increase the overall load on the system and it is not as reliable, because the user can override the polling interval. Changing the driver's behavior is safer and has minimal overhead.

Add names for the device types to be printed at probe when debugging is enabled. Note that the HXN type is referred to as G for now as that is the name the vendor uses. Signed-off-by: Johan Hovold <johan@kernel.org>
2021-03-17USB: serial: pl2303: tighten type HXN (G) detectionJohan Hovold1-12/+20
Tighten the detection of the new HXN (G) type instead of assuming that every device which doesn't support the old read request is an HXN. Signed-off-by: Johan Hovold <johan@kernel.org>
2021-03-17USB: serial: pl2303: rename legacy PL2303H typeJohan Hovold1-6/+6

2021-03-15USB: serial: io_edgeport: drop unneeded forward declarationsJiri Slaby1-44/+1
Forward declarations make the code larger and rewrites harder. Harder as they are often omitted from global changes. Remove forward declarations which are not really needed, i.e. the definition of the function is before its first use.
