+description: |
+ This binding describes a physical power output supplied by a
+ regulator providing efuse functionality (manual on/off control, and
+ auto-shutoff if current, voltage, or thermal limits are exceeded).
+
+ These may be found on systems such as "smart" network PDUs, and
+ typically supply power to devices entirely separate from the system
+ described by the device-tree by way of an external connector such as
+ an Open19 power cable:

+ compatible:
+ const: power-efuse

+ description:
+ phandle to the regulator providing power for the efuse
+
+ error-flags-cache-ttl-ms:
+ description:
+ The number of milliseconds the vout-supply regulator's error
+ flags should be cached before re-fetching them.
+
+required:
+ - compatible
+ - vout-supply
+
+additionalProperties: false

+examples:
+ - |
+ efuse {
+ compatible = "power-efuse";
+ vout-supply = <&efuse_reg>;
+ error-flags-cache-ttl-ms = <500>;
+ };
