   4 Subject: [PATCH] OMAP: DSS2: OMAPFB: swap front and back porches for both hsync and vsync
   5
   6 Framebuffer's left and right margins are relative to the active pixel
   7 area. Front and back porches are relative to the sync area.
   8
   9 Left margin was wrongly assigned to front porch (and right to back),
  10 this patch fixes it.
