PMIC ESM Binding
======================
Certain Power Management ICs contain safety handling logic within them,
allowing automatic reset of the board in case a safety error is signaled.
For this purpose, ESM (Error Signal Monitor) is implemented within
the PMIC running its own state machine.
Required properties :
- compatible : "ti,tps659413-esm"
Example
=======
&tps659413a {
esm: esm {
compatible = "ti,tps659413-esm";
};
};
