Subject: [PATCH V7 1/4] dt-bindings: mailbox: imx-mu: add SCU MU support
Date: Thu, 19 Mar 2020 15:49:50 +0800	[thread overview]
Message-ID: <1584604193-2945-2-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1584604193-2945-1-git-send-email-peng.fan@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

i.MX8/8X SCU MU is dedicated for communication between SCU
and Cortex-A cores from hardware design, it could not be reused
for other purpose. To use SCU MU more effectivly, add "fsl,imx8-scu-mu"
compatile to support fast IPC.
