  Even if an unsupported mode with a pixel clock larger than two times the
  264 MHz IPU HSP clock is set, don't divide by zero.

• 6541d7108   gpu: ipu-di: Add ipu_di_adjust_videomode() ... Browse Code »

  On some monitors, high resolution modes are not working, exhibiting
  pixel column truncation problems (for example, 1280x1024 displays as
  1280x1022).

  The function ipu_di_adjust_videomode() aims to fix these issues by
  adjusting a passed videomode to IPU restrictions. The function can
  be called from the drm_crtc_helper_funcs->mode_fixup() methods.

  13

  The i.MX Image Processing Unit (IPU) contains a number of image processing
  blocks that sit right in the middle between DRM and V4L2. Some of the modules,
  such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS
  Sensor Interface (CSI) and their FIFOs could be assigned to either framework,
  but others, such as the dma controller (IDMAC) and image converter (IC) can
  be used by both.
  The IPUv3 core driver provides an internal API to access the modules, to be
  used by both DRM and V4L2 IPUv3 drivers.
