[PATCH 3/4] arm64: dts: qcom: sc7280: Define EC and H1 nodes

Rajendra Nayak
2021-11-23T07:00:53Z

From: Kshitiz Godara <kgodara@codeaurora.org>

The IDP2 and CRD boards share the EC and H1 parts, so define
all related device nodes into a common file and include them
in the idp2 and crd dts files to avoid duplication.
