Subject: [PATCH V8 1/7] dt-bindings: remoteproc: imx_rproc: support i.MX8QXP
From: Peng Fan <peng.fan@....com>
Add i.MX8QXP compatible
Add a new property fsl,resource-id for SoC which supports SCFW.
This property is used to check whether remote process is under control
of Linux or not.
Add fsl,entry-address to specify the entry address which used by SCFW
to kick M4.
To i.MX8QM/QXP, when M4 is in the same hardware partition with Cortex-A
cores, need power up M4 through SCFW, then M4 could start. So introduce
power-domains property
