Subject: [PATCH 1/2] dt-bindings: mailbox: imx-mu: add i.MX8ULP S400 MU support
Date: Fri, 22 Oct 2021 18:18:55 +0800 [thread overview]
Message-ID: <20211022101856.8612-2-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20211022101856.8612-1-peng.fan@oss.nxp.com>
From: Peng Fan <peng.fan@nxp.com>
Similar to i.MX8QM/QXP SCU, i.MX8ULP SCU MU is dedicated for
communication between S400 and Cortex-A cores from hardware design,
it could not be reused for other purpose. To use S400 MU more
effectivly, add "fsl,imx8ulp-mu-s4" compatile to support fast IPC.
