Subject[PATCH V7 1/4] dt-bindings: mailbox: imx-mu: add SCU MU support
Date
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.
