Felipe writes: USB changes for v4.21 So it looks like folks are interested in dwc3 again. Almost 64% of the changes are in dwc3 this time around with some other bits in gadget functions and dwc2. There are two important parts here: a. removal of the waitqueue from dwc3's dequeue implementation, which will guarantee that gadget functions can dequeue from any context and; b. better method for starting isochronous transfers to avoid, as much as possible, missed isoc frames. Apart from these, we have the usual set of non-critical fixes and new features all over the place. * tag 'usb-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb: (56 commits) usb: dwc2: Fix disable all EP's on disconnect usb: dwc3: gadget: Disable CSP for stream OUT ep usb: dwc2: disable power_down on Amlogic devices Revert "usb: dwc3: pci: Use devm functions to get the phy GPIOs" USB: gadget: udc: s3c2410_udc: convert to DEFINE_SHOW_ATTRIBUTE usb: mtu3: fix dbginfo in qmu_tx_zlp_error_handler usb: dwc3: trace: add missing break statement to make compiler happy usb: dwc3: gadget: Report isoc transfer frame number usb: gadget: Introduce frame_number to usb_request usb: renesas_usbhs: Use SIMPLE_DEV_PM_OPS macro usb: renesas_usbhs: Remove dummy runtime PM callbacks usb: dwc2: host: use hrtimer for NAK retries usb: mtu3: clear SOFTCONN when clear USB3_EN if work as HS mode usb: mtu3: enable SETUPENDISR interrupt usb: mtu3: fix the issue about SetFeature(U1/U2_Enable) usb: mtu3: enable hardware remote wakeup from L1 automatically usb: mtu3: remove QMU checksum usb/mtu3: power down device ip at setup usb: dwc2: Disable power down feature on Samsung SoCs usb: dwc3: Correct the logic for checking TRB full in __dwc3_prepare_one_trb() ...
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
