Subject: [PATCH v2 0/2] powerpc: define and implement MPIC message register support
Date: Fri, 20 May 2011 11:36:37 -0500 [thread overview]
Message-ID: <1305909399-26969-1-git-send-email-meador_inge@mentor.com> (raw)
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.
