[RESEND PATCH v6 0/8] staging: fsl-mc: add dpio driver
This patch series adds the driver for the DPIO object which is a step to addressing the final item in the staging TODO list-- adding a functional driver on top of the bus driver. The DPIO driver is a dependency for other functional drivers such as Ethernet. An overview of the DPIO object and driver components are in patch 1. Patches 2-6 are internal components of the DPIO driver-- bit twiddling of hardware registers, DPAA2 data structures, and the queuing APIs exposed to other drivers. Patch 7 adds the fsl-mc driver for the DPIO object. It provides the probe/remove functions, demonstrating a working example of how fsl-mc drivers initialize, interact with the management complex hardware, map their mappable MMIO regions, initialize interrupts, register an ISR, etc. All other DPAA2 drivers will follow a similar initialization pattern. version 6 changes -fixed error in size of SG_SHORT_LEN_MASK -removed improper padding in DPIO command responses -fixed some minor checkpatch warnings version 5 changes -fixed typo in patch 5 that caused compile issue version 4 changes -removed the patch moving the bus driver out of staging, updated all paths referenced in dpio (e.g. includes) to be drivers/staging -defined macros for constants where needed -copyright updates -cleanup: fixed whitespace, alignment issues, typos, removed unneeded comments -fixed bug in SDQCR #define -adding missing free in an error path version 3 changes -zero memory allocated for a dpio store -replace hardcoded dequeue token with a #define and look for that token when checking for a new result version 2 changes (mostly feedback from Ioana Radulescu) -removed unused structs and defines in dpio command definitions -added setter/getter for the FD ctrl field -corrected comment for SG format_offset field description -added support for short length field in FD -fix bug in buffer release command, by setting bpid field -handle error (NULL) return value from qbman_swp_mc_complete() -fix bug in sending management commands where the verb was properly initialized -use service_select_by_cpu() for re-arming DPIO interrupts -replace use of NR_CPUS with num_possible_cpus() -handle error case where number of DPIOs exceeds number of possible CPUs -error message cleanup -updated MAINTAINERS file with proper location for both fsl-mc bus driver and dpio driver Ioana Radulescu (1): bus: fsl-mc: dpio: add APIs for DPIO objects Roy Pledge (6): bus: fsl-mc: dpio: add frame descriptor and scatter/gather APIs bus: fsl-mc: dpio: add global dpaa2 definitions bus: fsl-mc: dpio: add QBMan portal APIs for DPAA2 bus: fsl-mc: dpio: add the DPAA2 DPIO service interface bus: fsl-mc: dpio: add the DPAA2 DPIO object driver bus: fsl-mc: dpio: add maintainer for DPIO Stuart Yoder (1): bus: fsl-mc: dpio: add DPIO driver overview document MAINTAINERS |6 + drivers/staging/fsl-mc/bus/Kconfig | 10 + drivers/staging/fsl-mc/bus/Makefile |3 + drivers/staging/fsl-mc/bus/dpio/Makefile|9 + drivers/staging/fsl-mc/bus/dpio/dpio-cmd.h | 75 ++ drivers/staging/fsl-mc/bus/dpio/dpio-driver.c | 296 +++ drivers/staging/fsl-mc/bus/dpio/dpio-driver.txt | 135 +++ drivers/staging/fsl-mc/bus/dpio/dpio-service.c | 618 ++ drivers/staging/fsl-mc/bus/dpio/dpio.c | 224 + drivers/staging/fsl-mc/bus/dpio/dpio.h | 109 +++ drivers/staging/fsl-mc/bus/dpio/qbman-portal.c | 1033 +++ drivers/staging/fsl-mc/bus/dpio/qbman-portal.h | 469 ++ drivers/staging/fsl-mc/include/dpaa2-fd.h | 448 ++ drivers/staging/fsl-mc/include/dpaa2-global.h | 202 + drivers/staging/fsl-mc/include/dpaa2-io.h | 139 +++ 15 files changed, 3776 insertions(+) create mode 100644 drivers/staging/fsl-mc/bus/dpio/Makefile create mode 100644 drivers/staging/fsl-mc/bus/dpio/dpio-cmd.h create mode 100644 drivers/staging/fsl-mc/bus/dpio/dpio-driver.c create mode 100644 drivers/staging/fsl-mc/bus/dpio/dpio-driver.txt create mode 100644 drivers/staging/fsl-mc/bus/dpio/dpio-service.c create mode 100644 drivers/staging/fsl-mc/bus/dpio/dpio.c create mode 100644 drivers/staging/fsl-mc/bus/dpio/dpio.h create mode 100644 drivers/staging/fsl-mc/bus/dpio/qbman-portal.c create mode 100644 drivers/staging/fsl-mc/bus/dpio/qbman-portal.h create mode 100644 drivers/staging/fsl-mc/include/dpaa2-fd.h create mode 100644 drivers/staging/fsl-mc/include/dpaa2-global.h create mode 100644 drivers/staging/fsl-mc/include/dpaa2-io.h -- 2.9.3 ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

For example, be specific about which patches were affected by checkpatch and what fixes you made. Right now I can't tell. For an example, of what I'm talking about look at previous versions of this patch series.
