You should add the version prefix to the patches next time. e.g. [PATCH v4 ...] It is also recommended to add a Change-log in the cover letter explaining what changes were made in each revision. There are a bunch of checkpatch warnings in this series. You can use ./scripts/checkpatch.pl on the patches and fix the issues. > --- > > Pawel Laszczak (31): > usb: usbssp: Defined register maps and other useful structures. > usb: usbssp: Added some decoding functions. > usb: usbssp: Add trace events used in driver > usb: usbssp: Added USBSSP platform driver > usb: usbssp: Added first part of initialization sequence. > usb: usbssp: added template functions used by upper layer. > usb: usbssp: Initialization - added usbssp_mem_init > usb: usbssp: Added ring and segment handling functions. > usb: usbssp: add implementation of usbssp_mem_cleanup > usb: usbssp: added usbssp_trb_in_td function. > usb: usbssp: added function for stopping driver. > usb: usbssp: added functions for queuing commands. > usb: usbssp: addec procedure for handlin Port Status Change events. > usb: usbssp: added procedure handling command completion events. > usb: usbssp: added device controller error, transfer and SETUP > completion event. > usb: usbssp: added connect/disconnect procedures. > usb: usbssp: added implementation of usbssp_halt_endpoint function. > usb: usbssp: added handling of Port Reset event. > usb: usbssp: added support for USB enumeration process. > usb: usbssp: added queuing procedure for control transfer. > usb: usbssp: added queuing procedure for BULK and INT transfer. > usb: usbssp: added procedure removing request from transfer ring > usb: usbssp: added implementation of transfer events. > usb: usbssp: added detecting command timeout. > usb: usbssp: added implementation of usbssp interface. > usb: usbssp: added endpoint configuration functionality. > usb: usbssp: implements usbssp_gadget_ep_enable function > usb: usbssp: implemented usbssp_gadget_ep_disable function. > usb: usbssp: added support for LPM. > usb: usbssp: added support for TEST_MODE. > usb: usbssp: add pci to platform driver wrapper. > > drivers/usb/Kconfig | 2 + > drivers/usb/Makefile | 2 + > drivers/usb/usbssp/Kconfig | 29 + > drivers/usb/usbssp/Makefile | 15 + > drivers/usb/usbssp/gadget-dbg.c | 39 + > drivers/usb/usbssp/gadget-ep0.c | 571 +++++ > drivers/usb/usbssp/gadget-ext-caps.h | 102 + > drivers/usb/usbssp/gadget-if.c | 569 +++++ > drivers/usb/usbssp/gadget-mem.c | 1938 +++++++++++++++ > drivers/usb/usbssp/gadget-port.c | 287 +++ > drivers/usb/usbssp/gadget-ring.c | 3452 ++++++++++++++++++++++++++ > drivers/usb/usbssp/gadget-trace.c | 13 + > drivers/usb/usbssp/gadget-trace.h | 482 ++++ > drivers/usb/usbssp/gadget.c | 1909 ++++++++++++++ > drivers/usb/usbssp/gadget.h | 2373 ++++++++++++++++++ > drivers/usb/usbssp/usbssp-pci-wrap.c | 226 ++ > drivers/usb/usbssp/usbssp-plat.c | 186 ++ > 17 files changed, 12195 insertions(+) > create mode 100644 drivers/usb/usbssp/Kconfig > create mode 100644 drivers/usb/usbssp/Makefile > create mode 100644 drivers/usb/usbssp/gadget-dbg.c > create mode 100644 drivers/usb/usbssp/gadget-ep0.c > create mode 100644 drivers/usb/usbssp/gadget-ext-caps.h > create mode 100644 drivers/usb/usbssp/gadget-if.c > create mode 100644 drivers/usb/usbssp/gadget-mem.c > create mode 100644 drivers/usb/usbssp/gadget-port.c > create mode 100644 drivers/usb/usbssp/gadget-ring.c > create mode 100644 drivers/usb/usbssp/gadget-trace.c > create mode 100644 drivers/usb/usbssp/gadget-trace.h > create mode 100644 drivers/usb/usbssp/gadget.c > create mode 100644 drivers/usb/usbssp/gadget.h > create mode 100644 drivers/usb/usbssp/usbssp-pci-wrap.c > create mode 100644 drivers/usb/usbssp/usbssp-plat.c > -- cheers, -roger Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
