The Synopsys USB device controller requires all OUT transfer request lengths to be aligned to max packet size. The mass storage gadgets do not meet this requirement for Super Speed. The gadgets already have a function which performs this alignment for CBW packets, so use it for data packets too. The alternative would be to implement bounce buffers in the DWC3 driver, but that could have a significant impact on performance. This version is based upon a more-correct patch written by Alan Stern. Signed-off-by: NPaul Zimmerman <paulz@synopsys.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

The code in the MIDI gadget was already sort of prepared for multi-port configuration, so the streaming logic itself didn't need much tweaking. However, the descriptors change when the number of ports do, and so some rework of the the preparation algorithms were necessary. Successfully tested on Linux and Max OS X hosts for both input and output streams.

Make use of the newly added MIDI function in f_midi.c and strip down the MIDI gadget code radically. Also use the generic framework function to avoid code duplication and rename some symbols to bring them in sync with other code in the gadget framework.

This patch adds f_midi.c to implement a USB gadget function that works with the composite framework, so it can be combined with other USB functions. The code for the ALSA/MIDI logic was taken from the midi device gadget, other parts have been rewritten to benefit from the dynamic descriptor allocation features. This was successfully tested on an OMAP3 board. Signed-off-by: NDaniel Mack <zonque@gmail.com> Cc: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: NFelipe Balbi <balbi@ti.com>

An older version of the databook said to wait for the FIFO to drain, but that has been removed from the newer databooks.

Add to the dev_state and alloc_async structures the user namespace corresponding to the uid and euid. Pass these to kill_pid_info_as_uid(), which can then implement a proper, user-namespace-aware uid check. Changelog: Sep 20: Per Oleg's suggestion: Instead of caching and passing user namespace, uid, and euid each separately, pass a struct cred. Sep 26: Address Alan Stern's comments: don't define a struct cred at usbdev_open(), and take and put a cred at async_completed() to ensure it lasts for the duration of kill_pid_info_as_cred().

This patch (as1488) improves the comments and logic in uhci-hcd's suspend routine. The existing comments are hard to understand and don't give a good idea of what's really going on. The question of whether EGSM (Enter Global Suspend Mode) and RD (enable Resume Detect interrupts) can be useful when they're not both set is difficult. The spec doesn't give any details on how they interact with system wakeup, although clearly they are meant to be used together. To be safe, the patch changes the subroutine so that neither bit gets set unless they both do. There shouldn't be any functional changes from this; only systems that are designed badly or broken in some way need to avoid using those bits.

This patch (as1486) implements the kernel's new wakeup policy for USB host controllers. Since they don't generate wakeup requests on their but merely forward requests from their root hubs toward the CPU, they should be enabled for wakeup by default. Also, to be compliant with both the old and new policies, root hubs should not be enabled for remote wakeup by default. Userspace must enable it explicitly if it is desired.

This removes the need of ifdefs within the init function and with it the headache about the correct clean without bus X but with bus/platform Y & Z. xhci-pci is only compiled if CONFIG_PCI is selected which can be de-selected now without trouble. For now the result is kinda useless because we have no other glue code.

xhci_pci_setup() is split into three pieces: - xhci_gen_setup() The major remaining of xhci_pci_setup() is now containing the generic part of the xhci setup. It allocates the xhci struct, setup hcs_params? and friends, performs xhci_halt(), xhci_init and so one. It also obtains the quirks via a callback - xhci_pci_quirks() It checks the origin of the xhci core and sets core specific quirks. - xhci_pci_setup() PCI specific setup functions. Besides calling xhci_gen_setup() with xhci_pci_quirks() as an argument it performs PCI specific setup like obtaining the address of sbrn via a PCI config space.
