[PATCH 2/2] dt-bindings: firmware: add reset-controller property

From: Piyush Mehta
Date: Wed Jun 07 2023 - 02:54:06 EST


The reset controller is responsible for managing both device-level resets
and individual PMC (Power Management Controller) block resets.

To facilitate this functionality reset-controller property is added to the
firmware device tree binding.
