	Hi Simon, Magnus,

This patch series adds chosen/stdout-path to the various shmobile DTS files
that are used for reference or multi-platform builds.

This serves two purposes:
  1. It makes automatic console selection work in the absence of a "console="
     parameter on the kernel command line, allowing to remove "console="
     parameters from chosen/bootargs on many platforms.
     Note that these "console=" parameters are still needed in some cases:
       a. If console output is wanted on two consoles devices (graphical and
          serial consoles), like on armadillo and kzm9g,
       b. When using a non-default baud for the serial console, like on
          henninger and alt,
  2. It will allow the PM domain code to find the PM domain for the console
     device, to make "no_console_suspend" work in the DT case.
     For now, this will matter on armadillo.

The first two patches are small cleanups for emev2 dtsi, on top of which the
change for kzm9d is built.
Thanks, I have queued these up for v3.19.
I spoke a little too soon.

While testing these patches I noticed that the koelsch patch
cases there to be no kernel output to the console (during boot)
when booting using legacy C.

I assume that this is due to removing
console=ttySC6,115200 from bootargs.

I also assume this affects all boards that can still
be booted using legacy C.

I have dropped this series for now.
