      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.
