Hi Kishon, > Ported DWC3 driver from linux kernel v3.16 to uboot and enabled DFU > in DRA7xx. Tested only with DFU ram.
I'm afraid that only testing the code with DFU ram is not enough. I'd _appreciate_ if you had CCed other people involved in DFU/UDC/USB development to this RFC. I've CCed Marek Vasut - the USB custodian. The whole series seems like a huge improvement from the base code - which is 2.6.36 based one... > > While I kept the dwc3 driver pretty much the same from linux kernel, > I have created a single driver for both USB2 and USB3 PHY > programming. I concern about driver model compliance. Simon Glass has put a lot of effort to convert Exynos' UART and GPIO to it. Hence, I believe that potential UDC/PHY rework shall comply with Simon's device model work. Therefore, I've CC'ed Simon as well. > I have also adapted udc-core from linux kernel so that > we can cleanly link the gadet driver with the controller driver. > > This series was created on top of > commit 61e76f53708cf082ef9061a140b57df3513b8ba1 > Merge: 76b2102 3d83e67 > Author: Tom Rini <[email protected]> > Date: Tue Jun 10 20:37:00 2014 -0400 > > Merge branch 'master' of git://git.denx.de/u-boot-usb > > Let me know of any feedback and suggestions. > > Known Issues: > DWC3 is not enumerating consistently. > > Kishon Vijay Abraham I (13): > include: linux: preparation for porting dwc3 from linux kernel > usb: gadget: udc-core: Add minimal udc-core from linux kernel > ARM: DRA7: Enable clocks for USB OTGSS and USB PHY > usb: dwc3: Add dwc3 driver > usb: dwc3-omap: Add dwc3 glue driver for OMAP > usb: dwc3: TI PHY: PHY driver for dwc3 in TI platforms > usb: gadget: g_dnl: Explicitly set the max packet size in descriptor > common: cmd_dfu: invoke board_usb_cleanup() for cleaning up > common: cmd_dfu: add an API that takes controller index for handling > interrupts > board: ti: DRA7: added USB initializtion code > commom: usb: implement "__weak" functions to make compiler happy > include: configs: Enable DWC3 and DFU in DRA7xx > dwc3: core: Change the bounce buffer size to 4096 > > Makefile | 1 + > arch/arm/cpu/armv7/omap5/hw_data.c | 14 + > arch/arm/cpu/armv7/omap5/prcm-regs.c | 6 +- > arch/arm/include/asm/arch-omap5/omap.h | 12 + > arch/arm/include/asm/omap_common.h | 4 +- > board/ti/dra7xx/evm.c | 106 ++ > common/cmd_dfu.c | 2 + > common/usb.c | 18 + > drivers/usb/dwc3/Makefile | 10 + > drivers/usb/dwc3/core.c | 640 +++++++ > drivers/usb/dwc3/core.h | 961 +++++++++++ > drivers/usb/dwc3/dwc3-omap.c | 447 +++++ > drivers/usb/dwc3/ep0.c | 1045 ++++++++++++ > drivers/usb/dwc3/gadget.c | 2841 > ++++++++++++++++++++++++++++++++ > drivers/usb/dwc3/gadget.h | 163 ++ > drivers/usb/dwc3/io.h | 52 + > drivers/usb/dwc3/linux-compat.h | 132 ++ > drivers/usb/dwc3/ti_usb_phy.c | 269 +++ > drivers/usb/gadget/Makefile | 1 + > drivers/usb/gadget/composite.c | 3 +- > drivers/usb/gadget/g_dnl.c | 1 + > drivers/usb/gadget/udc-core.c | 229 +++ > include/configs/dra7xx_evm.h | 59 + > include/configs/ti_omap5_common.h | 1 + > include/dwc3-omap-uboot.h | 32 + > include/dwc3-uboot.h | 26 + > include/linux/compat.h | 12 +- > include/linux/usb/composite.h | 12 + > include/linux/usb/dwc3-omap.h | 19 + > include/linux/usb/gadget.h | 75 +- > include/linux/usb/otg.h | 20 + > include/ti-usb-phy-uboot.h | 22 + > include/usb.h | 7 + > include/usb/lin_gadget_compat.h | 8 +- 34 files changed, > 7236 insertions(+), 14 deletions(-) create mode 100644 > drivers/usb/dwc3/Makefile create mode 100644 drivers/usb/dwc3/core.c > create mode 100644 drivers/usb/dwc3/core.h > create mode 100644 drivers/usb/dwc3/dwc3-omap.c > create mode 100644 drivers/usb/dwc3/ep0.c > create mode 100644 drivers/usb/dwc3/gadget.c > create mode 100644 drivers/usb/dwc3/gadget.h > create mode 100644 drivers/usb/dwc3/io.h > create mode 100644 drivers/usb/dwc3/linux-compat.h > create mode 100644 drivers/usb/dwc3/ti_usb_phy.c > create mode 100644 drivers/usb/gadget/udc-core.c > create mode 100644 include/dwc3-omap-uboot.h > create mode 100644 include/dwc3-uboot.h > create mode 100644 include/linux/usb/dwc3-omap.h > create mode 100644 include/linux/usb/otg.h > create mode 100644 include/ti-usb-phy-uboot.h > -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
