2020-02-17xhci: Do not open code __print_symbolic() in xhci trace eventsSteven Rostedt (VMware)
libtraceevent (used by perf and trace-cmd) failed to parse the xhci_urb_dequeue trace event. This is because the user space trace event format parsing is not a full C compiler. It can handle some basic logic, but is not meant to be able to handle everything C can do. In cases where a trace event field needs to be converted from a number to a string, there's the __print_symbolic() macro that should be used: See samples/trace_events/trace-events-sample.h Some xhci trace events open coded the __print_symbolic() causing the user spaces tools to fail to parse it. This has to be replaced with __print_symbolic() instead.

2020-02-12USB: Select better matching USB drivers when availableBastien Nocera
Now that USB device drivers can reuse code from the generic USB device driver, we need to make sure that they get selected rather than the generic driver. Add an id_table and match vfunc to the usb_device_driver struct, which will get used to select a better matching driver at ->probe time. This is a similar mechanism to that used in the HID drivers, with the generic driver being selected unless there's a better matching one found in the registered drivers (see hid_generic_match() in drivers/hid/hid-generic.c).

2020-02-12usb: typec: Allow power role swapping even without USB PDHeikki Krogerus
Even though originally the USB Type-C Specification did not describe the steps for power role swapping without USB PD contract in place, it did not actually mean power role swap without USB PD was not allowed. The USB Type-C Specification did not clearly separate the data and power roles until in the release 1.2 which is why there also were no clear steps for the scenario where only the power role was swapped without USB PD contract before that. Since in the latest version of the specification the power role swap without USB PD is now clearly mentioned as allowed operation, removing the check that prevented power role swap without USB PD support.

2020-02-10usb: host: ehci-platform: add a quirk to avoid stuckYoshihiro Shimoda
Since EHCI/OHCI controllers on R-Car Gen3 SoCs are possible to be getting stuck very rarely after a full/low usb device was disconnected. To detect/recover from such a situation, the controllers require a special way which poll the EHCI PORTSC register and changes the OHCI functional state. So, this patch adds a polling timer into the ehci-platform driver, and if the ehci driver detects the issue by the EHCI PORTSC register, the ehci driver removes a companion device (= the OHCI controller) to change the OHCI functional state to USB Reset once. And then, the ehci driver adds the companion device again.

2020-02-09Merge tag 'zonefs-5.6-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs Pull new zonefs file system from Damien Le Moal: "Zonefs is a very simple file system exposing each zone of a zoned block device as a file. Unlike a regular file system with native zoned block device support (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the sequential write constraint of zoned block devices to the user. As a result, zonefs is not a POSIX compliant file system. Its goal is to simplify the implementation of zoned block devices support in applications by replacing raw block device file accesses with a richer file based API, avoiding relying on direct block device file ioctls which may be more obscure to developers. One example of this approach is the implementation of LSM (log-structured merge) tree structures (such as used in RocksDB and LevelDB) on zoned block devices by allowing SSTables to be stored in a zone file similarly to a regular file system rather than as a range of sectors of a zoned device. The introduction of the higher level construct "one file is one zone" can help reducing the amount of changes needed in the application while at the same time allowing the use of zoned block devices with various programming languages other than C. Zonefs IO management implementation uses the new iomap generic code. Zonefs has been successfully tested using a functional test suite (available with zonefs userland format tool on github) and a prototype implementation of LevelDB on top of zonefs" * tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs: zonefs: Add documentation fs: New zonefs file system
