      usb: musb: drop unneeded musb_debug trickery · 5c8a86e1
      Felipe Balbi 提交于
      We have a generic way of enabling/disabling
      different debug messages on a driver called
      DYNAMIC_PRINTK. Anyone interested in enabling
      just part of the debug messages, please read
      the documentation under:
      
      Documentation/dynamic-debug-howto.txt
      
      for information on how to use that great
      infrastructure.

      USB: musb: blackfin: work around anomaly 05000450 · 13254307
      Mike Frysinger 提交于
      DMA mode 1 data corruption anomaly on Blackfin systems.  This issue is
      specific to the Blackfin silicon as the bug appears to be related to the
      connection of the musb ip to the bus/dma fabric.
      
      Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105)
      DMA mode 1 allows large size transfers to generate a single interrupt
      at the end of the entire transfer.  The transfer is split up in packets
      of length specified in the Maximum Packet Size field for that endpoint.
      If the transfer size is not an integer multiple of the Maximum Packet
      Size, a short packet will be present at the end of the transfer.
      
      Under certain conditions this packet may be corrupted in the USB FIFO.
      
      Workaround:
      Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA
      mode 0 to transfer the short packet.
      
      As an example if your transfer size is 33168 bytes and Maximum Packet
      Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and
      the remainder (33168 mod 512) in DMA mode 0.

      usb: musb: disable double buffering when it's broken · 06624818
      Felipe Balbi 提交于
      We know that blackfin doesn't support double
      buffering feature as of today. So we add a
      flag set by musb_platform_init() to forcefully
      disable that feature.
      
      Such flag is created and marked as deprecated
      to force us to find a solution for the missing
      double buffering support on blackfin.

      usb: musb: make all glue layer export struct musb_platform_ops · 743411b3
      Felipe Balbi 提交于
      preparing to a big refactor on musb code. We need
      to be able to compile in all glue layers (or at
      least all ARM-based ones) together and have a
      working binary.
      
      While preparing for that, we move every glue
      layer to export only one symbol, which is
      a struct musb_platform_ops, and make all
      other functions static.
      
      Later patches will come to allow for compiling
      all glue layers together and have a working
      binary.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.
