Hi Geert,

As this appears to be a bug fix I would like to accompany this patch with
some text describing when the problem was introduced and what its effects
are. In short a rough guide to if it should be applied to -stable. To that
end I prepared the following which I would appreciate your feedback on.

* ARM: shmobile: r8a7740 dtsi: Correct IIC0 parent clock  

  This problem was introduced when clock support was added DT for the
  r8a7740 by d9ffd583bf345e2ea ("ARM: shmobile: r8a7740: add SoC clocks to
  DTS") in v3.17.

  I am not aware of any run-time effect of this problem.
