ESM (Error Signaling Module) is a fundamental IP responsible for
handling safety events. The driver currently present in U-Boot is
responsible for configuring ESM. This patch series adds dt-binding and
nodes for J721E and J7200. This goes towards end goal of having DTB sync
with that of U-Boot as well as ensuring completeness of hardware
description in devicetree.
