Document MMIO support used to boot the CM7 on MX8MN/MP instead and discern MMIO interface using DT compatible string. Document GPR register syscon phandle which is required by the MMIO interface too. Signed-off-by: Marek Vasut --- Note that the MMIO being discerned using compatible string is similar approach to "st,stm32mp1-rcc" vs "st,stm32mp1-rcc-secure". --- Cc: Bjorn Andersson Cc: Conor Dooley Cc: Fabio Estevam Cc: Krzysztof Kozlowski Cc: Mathieu Poirier Cc: NXP Linux Team Cc: Peng Fan Cc: Pengutronix Kernel Team Cc: Rob Herring Cc: Sascha Hauer Cc: Shawn Guo Cc: devicetree@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org Cc: linux-remoteproc@vger.kernel.org --- .../bindings/remoteproc/fsl,imx-rproc.yaml | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml b/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml index c940199ce89df..78bb976f738ee 100644 --- a/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml +++ b/Documentation/devicetree/bindings/remoteproc/fsl,imx-rproc.yaml @@ -20,7 +20,9 @@ properties: - fsl,imx7ulp-cm4 - fsl,imx8mm-cm4 - fsl,imx8mn-cm7 + - fsl,imx8mn-cm7-mmio - fsl,imx8mp-cm7 + - fsl,imx8mp-cm7-mmio - fsl,imx8mq-cm4 - fsl,imx8qm-cm4 - fsl,imx8qxp-cm4 @@ -30,6 +32,11 @@ properties: clocks: maxItems: 1 + gpr: + $ref: /schemas/types.yaml#/definitions/phandle + description: + Phandle to IOMUXC GPR block which provide access to CM7 CPUWAIT bit. + syscon: $ref: /schemas/types.yaml#/definitions/phandle description: @@ -84,6 +91,19 @@ properties: required: - compatible +allOf: + - if: + properties: + compatible: + not: + contains: + enum: + - fsl,imx8mn-cm7-mmio + - fsl,imx8mp-cm7-mmio + then: + properties: + gpr: false + additionalProperties: false examples:
