Hi Sergei, Hi All,

I do not expect patch 3 of this series to got through
the renesas tree, however, I have included it and the other three patches
in this series to a topic branch in the renesas tree, topic/r-car-stat.

The base of the topic branch is:
* a merge of renesas.git next and libata-dev.git upstream, and;
* a boot fix for Marzen which I plan to add to next once it is reviewed:
  "ARM: shmobile: r8a7779: Correct TMU clock support again" (v3).

With this in place I built a kernel using the marzen_defconfig and booted it.
However, I wonder if I am missing a kernel option, or perhaps something
else of a minor nature as I see the following:

# dmesg | grep sata
sata_rcar sata_rcar: coherent DMA mask is unset
sata_rcar sata_rcar: failed to start port 0 (errno=-12)
sata_rcar: probe of sata_rcar failed with error -12
