I'm not sure any of these are worth backporting to stable. I believe
actually only these two are bugfixes:

  [PATCH 06/12] ARM: dts: mmp3: Extend the MPMU reg range
  [PATCH 12/12] ARM: dts: mmp3: Fix the CCIC interrupts

The first one only affects the audio, but the MMP I2S driver doesn't
work on MMP3 yet. The second one affects the camera, but the only board
DTS shipped at this point doesn't have one. Therefore both are somewhat
inconequential for older kernels.
