I'm just trying to pick up a patch series submitted 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=305b332b46901c82d762e44d2ef8c96107a0c94e Previously I sent this series out as two separate series, to try to make the review a little easier. However, the partial series was causing some confusion as well, so this time I've sent almost all of it in one go. NOTE: I unfortunately don't have any deep knowledge of the hardware other then the previously submitted code and what I can intuit from testing, but I tried to document the previously undocumented bindings as best I could, fixed up a few minor checkpatch issues and tried to address previous feedback as best I could. I'd greatly appreciate feedback or thoughts! thanks -john New in v3: * Avoiding adding a hisi specific dwc3 binding and instead trying to make the dwc core binding more flexible as suggsted by Rob Herring. * Made the GCTL soft reset unconditional as suggested by Jack Pham. * Given the negative feedback on the usb class role-switch notifier method for the hub logic to hook into, I've reworked the hub logic to be an usb-role-switch intermediary. * Lots of minor fixups and cleanups, some reported by the kbuild test robot <lkp@xxxxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Cc: Rob Herring <robh+dt@xxxxxxxxxx> Cc: Mark Rutland <mark.rutland@xxxxxxx> CC: ShuFan Lee <shufan_lee@xxxxxxxxxxx> 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: Jack Pham <jackp@xxxxxxxxxxxxxx> Cc: linux-usb@xxxxxxxxxxxxxxx Cc: devicetree@xxxxxxxxxxxxxxx John Stultz (6): dt-bindings: usb: rt1711h: Add connector bindings dt-bindings: usb: dwc3: Allow clock list & resets to be more flexible usb: dwc3: Rework clock initialization to be more flexible usb: dwc3: Rework resets initialization to be more flexible dt-bindings: usb: generic: Add role-switch-default-host binding usb: dwc3: Add host-mode as default support Yu Chen (5): usb: dwc3: Execute GCTL Core Soft Reset while switch modes usb: dwc3: Increase timeout for CmdAct cleared by device controller usb: dwc3: Registering a role switch in the DRD code. dt-bindings: misc: Add bindings for HiSilicon usb hub and data role switch functionality on HiKey960 misc: hisi_hikey_usb: Driver to support usb functionality of Hikey960 .../bindings/misc/hisilicon-hikey-usb.txt | 40 ++++ .../devicetree/bindings/usb/dwc3.txt | 5 +- .../devicetree/bindings/usb/generic.txt | 5 + .../bindings/usb/richtek,rt1711h.txt | 29 +++ drivers/misc/Kconfig | 6 + drivers/misc/Makefile | 1 + drivers/misc/hisi_hikey_usb.c | 178 ++++++++++++++++++ drivers/usb/dwc3/Kconfig | 1 + drivers/usb/dwc3/core.c | 38 ++-- drivers/usb/dwc3/core.h | 6 + drivers/usb/dwc3/drd.c | 78 +++++++- drivers/usb/dwc3/gadget.c | 2 +- 12 files changed, 369 insertions(+), 20 deletions(-) create mode 100644 Documentation/devicetree/bindings/misc/hisilicon-hikey-usb.txt create mode 100644 drivers/misc/hisi_hikey_usb.c -- 2.17.1
