The safety signals have their separate paths within17 the SoC, and they are handled by the ESM, which routes them to the proper18 destination, which can be system reset, interrupt controller, etc. In the19 simplest configuration the signals are just routed to reset the SoC.20 21properties:22 compatible:23 const: ti,j721e-esm24 25 reg:26 maxItems: 127 28 ti,esm-pins:29 $ref: /schemas/types.yaml#/definitions/uint32-array30 description:31 integer array of ESM interrupt pins to route to external event pin32 which can be used to reset the SoC.33 minItems: 134 maxItems: 25535 36required:37 - compatible38 - reg39 - ti,esm-pins40 41additionalProperties: false42 43examples:44 - |45 bus {46 #address-cells = <2>;47 #size-cells = <2>;48 esm@700000 {49 compatible = "ti,j721e-esm";50 reg = <0x0 0x700000 0x0 0x1000>;51 ti,esm-pins = <344>, <345>;52 };53 };54
