From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Meador Inge To: linuxppc-dev@lists.ozlabs.org Subject: [PATCH v2 0/2] powerpc: define and implement MPIC message register support Date: Fri, 20 May 2011 11:36:37 -0500 Message-Id: <1305909399-26969-1-git-send-email-meador_inge@mentor.com> Cc: openmcapi-dev@googlegroups.com, devicetree-discuss@lists.ozlabs.org, Hollis Blanchard List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , 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.
