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>;
|
||
|
};
