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 Reviewed-by: Rob Herring <robh@...nel.org> Signed-off-by: Peng Fan <peng.fan@....com> --- .../bindings/remoteproc/fsl,imx-rproc.yaml | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml b/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml index 3a1f59ad79e2..70322e57b6ff 100644 --- a/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml +++ b/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml @@ -22,6 +22,7 @@ properties: - fsl,imx8mn-cm7 - fsl,imx8mp-cm7 - fsl,imx8mq-cm4 + - fsl,imx8qxp-cm4 - fsl,imx8ulp-cm33 - fsl,imx93-cm33 @@ -54,12 +55,26 @@ properties: minItems: 1 maxItems: 32 + power-domains: + maxItems: 8 + fsl,auto-boot: $ref: /schemas/types.yaml#/definitions/flag description: Indicate whether need to load the default firmware and start the remote processor automatically. + fsl,entry-address: + $ref: /schemas/types.yaml#/definitions/uint32 + description: + Specify CPU entry address for SCU enabled processor. + + fsl,resource-id: + $ref: /schemas/types.yaml#/definitions/uint32 + description: + This property is to specify the resource id of the remote processor in SoC + which supports SCFW + required: - compatible -- 2.37.1
