From mboxrd@z Thu Jan 1 00:00:00 1970 From: John Stultz Subject: [RFC][PATCH 0/3] dwc3 role-switch handling for HiKey960 Date: Wed, 2 Oct 2019 23:16:14 +0000 Message-ID: <20191002231617.3670-1-john.stultz@linaro.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: lkml Cc: John Stultz , Greg Kroah-Hartman , Rob Herring , Mark Rutland , Heikki Krogerus , Suzuki K Poulose , Chunfeng Yun , Yu Chen , Felipe Balbi , Hans de Goede , Andy Shevchenko , Jun Li , Valentin Schneider , linux-usb@vger.kernel.org, devicetree@vger.kernel.org List-Id: devicetree@vger.kernel.org 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 Cc: Rob Herring Cc: Mark Rutland Cc: Heikki Krogerus Cc: Suzuki K Poulose Cc: Chunfeng Yun Cc: Yu Chen Cc: Felipe Balbi Cc: Hans de Goede Cc: Andy Shevchenko Cc: Jun Li Cc: Valentin Schneider Cc: linux-usb@vger.kernel.org Cc: devicetree@vger.kernel.org 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
