[Meador Inge]

Scott, I addressed your feedback in this patch set:

   * 1/2 - http://lists.ozlabs.org/pipermail/linuxppc-dev/2011-May/090405.html
   * 2/2 - http://lists.ozlabs.org/pipermail/linuxppc-dev/2011-May/090406.html

Ben, my Cc for you didn't go through the first time.


> This patch set defines a binding for FSL MPIC message registers and implements
> an API for accessing those message registers.  Testing was done on a MPC8572DS
> in an Linux-Linux AMP setup using OpenMCAPI (www.openmcapi.org) to communicate
> between OS instances.  The message register API is used by the OpenMCAPI shared
> memory driver to send notifications between cores.
> 
> * v2 - Incorporate feedback from Scott Wood
>   * Make binding less implementation specific.
>   * Add 'mpic-' prefix to message register node properties and aliases.
>   * Remove 'interrupt-parent' from binding.
>   * Fixed some example bugs with receive masks.
