      video: pxa3xx-gcu: Simplify the logic to exit while loop in pxa3xx_gcu_wait_idle · 688ec344
      Axel Lin authored
      If wait_event_interruptible_timeout returns a positive value, it means
      the condition evaluated is true. Which means priv->shared->hw_running is false.
      And then we will exit the loop.
      
      This patch simplifies the logic to exit the while loop.

      ARM: Samsung: Rework platform data of s3c-fb driver · 79d3c41a
      Thomas Abraham authored
      For all the Samsung SoC based boards which have the platform data for
      s3c-fb driver, the 'default_win' element in the platform data is removed
      and the lcd panel video timing values are moved out of individual window
      configuration data.

      ARM: s3c64xx: Decouple lcd type from display controller window data · 884924be
      Thomas Abraham authored
      The display controller window data should contain window configuration data
      for only one type of lcd panel. So, for real6410 and mini6410 boards, split
      the existing display controller window data, which contains window
      configuration data for two different types of lcd panels, into two seperate
      instances and register one of them depending on the type of the lcd panel
      detected at runtime.
      
      This is a prerequisite change for a subsequent commit that reorders the
      platform data of display controller by moving video interface timing out
      of window setup data.

      video: s3c-fb: remove 'default_win' element from platform data · 3c582647
      Thomas Abraham authored
      The decision to enable or disable the data output to the lcd panel from
      the controller need not be based on the value of 'default_win' element
      in the platform data. Instead, the data output to the panel is enabled
      if any of the windows are active, else data output is disabled.

      video: s3c-fb: move video interface timing out of window setup data · a4196feb
      Thomas Abraham authored
      The video interface timing is independent of the window setup data.
      The resolution of the window can be smaller than that of the lcd
      panel to which the video data is output.
      
      So move the video timing data from the per-window setup data to the
      platform specific section in the platform data. This also removes
      the restriction that atleast one window should have the same
      resolution as that of the panel attached.

      tcm_fc: Add abort flag for gracefully handling exchange timeout · e1c40382
      Mark Rustad authored
      Add abort flag and use it to terminate processing when an exchange
      is timed out or is reset. The abort flag is used in place of the
      transport_generic_free_cmd function call in the reset and timeout
      cases, because calling that function in that context would free
      memory that was in use. The aborted flag allows the lifetime to
      be managed in a more normal way, while truncating the processing.
      
      This change eliminates a source of memory corruption which
      manifested in a variety of ugly ways.

      Pull arch/tile bug fixes from Chris Metcalf:
       "This includes Paul Gortmaker's change to fix the <asm/system.h>
        disintegration issues on tile, a fix to unbreak the tilepro ethernet
        driver, and a backlog of bugfix-only changes from internal Tilera
        development over the last few months.
      
        They have all been to LKML and on linux-next for the last few days.
        The EDAC change to MAINTAINERS is an oddity but discussion on the
        linux-edac list suggested I ask you to pull that change through my
        tree since they don't have a tree to pull edac changes from at the
        moment."

       "Two fixes for regressions:
         * one is a workaround that will be removed in v3.5 with proper fix in
           the tip/x86 tree,
         * the other is to fix drivers to load on PV (a previous patch made
           them only load in PVonHVM mode).
      
        The rest are just minor fixes in the various drivers and some cleanup
        in the core code."

      Pull MMC fixes from Chris Ball:
       - Disable use of MSI in sdhci-pci, which caused multiple chipsets to
         stop working in 3.4-rc1.  I'll wait to turn this on again until we
         have a chipset whitelist for it.
       - Fix a libertas SDIO powered-resume regression introduced in 3.3;
         thanks to Neil Brown and Rafael Wysocki for this fix.
       - Fix module reloading on omap_hsmmc.
       - Stop trusting the spec/card's specified maximum data timeout length,
         and use three seconds instead.  Previously we used 300ms.
      
      Also cleanups and fixes for s3c, atmel, sh_mmcif and omap_hsmmc.
