The safety signals have their separate paths within the SoC, +and they are handled by the ESM, which routes them to the proper +destination, which can be system reset, interrupt controller, etc. In +the simplest configuration the signals are just routed to reset the +SoC. + +Required properties : +- compatible : "ti,j721e-esm" +- ti,esm-pins : integer array of esm events IDs to route to external event + pin which can be used to reset the SoC. The array can + have arbitrary amount of event IDs listed on it. + +Example +======= + + main_esm: esm@700000 { + compatible = "ti,j721e-esm"; + reg = <0x0 0x700000 0x0 0x1000>; + ti,esm-pins = <344>, <345>; + }; |
