OK, we'll discuss this on the #linux-sh IRC channel and if no one objects,
I'm going to apply the series.

It depends on what Yoshinori plans for the device tree conversion. The
latest version of his series was posted here [1]. But he promised to
send a rebased and updated version soon.

Yes, that would be greatly appreciated. Please go ahead.

FWIW, I am currently on vacation until August 15th, so I might be a bit
