I'm just trying to pick up parts of a patch previously by Yu Chen to get HiKey960 dev-board's USB functionality working. The current full patchset can be found here: https://git.linaro.org/people/john.stultz/android-dev.git/log/?id=12289c95c89e0e3173f8da1ebd3a29e52fd50a44 I don't have any real knowledge of the hardware other then the code, and what I can intuit from testing, but I tried to document the previously undocumented bindings as best I could and fixed up a few minor checkpatch issues. I'd greatly appreciate feedback or thoughts! thanks -john Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Cc: Rob Herring <robh+dt@xxxxxxxxxx> Cc: Mark Rutland <mark.rutland@xxxxxxx> Cc: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx> Cc: Suzuki K Poulose <suzuki.poulose@xxxxxxx> Cc: Chunfeng Yun <chunfeng.yun@xxxxxxxxxxxx> Cc: Yu Chen <chenyu56@xxxxxxxxxx> Cc: Felipe Balbi <balbi@xxxxxxxxxx> Cc: Hans de Goede <hdegoede@xxxxxxxxxx> Cc: Andy Shevchenko <andy.shevchenko@xxxxxxxxx> Cc: Jun Li <lijun.kernel@xxxxxxxxx> Cc: Valentin Schneider <valentin.schneider@xxxxxxx> Cc: linux-usb@xxxxxxxxxxxxxxx Cc: devicetree@xxxxxxxxxxxxxxx John Stultz (1): dt-bindings: usb: generic: Add role-switch-default-host binding Yu Chen (2): usb: roles: Add usb role switch notifier. usb: dwc3: Registering a role switch in the DRD code. .../devicetree/bindings/usb/generic.txt | 5 ++ drivers/usb/dwc3/Kconfig | 1 + drivers/usb/dwc3/core.h | 6 ++ drivers/usb/dwc3/drd.c | 78 ++++++++++++++++++- drivers/usb/roles/class.c | 35 ++++++++- include/linux/usb/role.h | 16 ++++ 6 files changed, 139 insertions(+), 2 deletions(-) -- 2.17.1
