[PATCH v2 1/2] dt-bindings: Add power-efuse binding

From: Zev Weiss
Date: Mon Mar 07 2022 - 20:18:37 EST


This can be used to describe a power output supplied by a regulator
device that the system controls.

+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:

+ The number of milliseconds the vout-supply regulator's error
+ flags should be cached before re-fetching them.
