-Texas Instruments K3 ESM Binding
-======================
-
-ESM (Error Signaling Module) is an IP block on TI K3 devices that allows
-handling of safety events somewhat similar to what interrupt controller
-would do. 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>;
- };
