Subject: [PATCH 3/4] arm64: dts: qcom: sc7280: Define EC and H1 nodes
Date:   Tue, 23 Nov 2021 12:30:12 +0530
Message-Id: <1637650813-16654-4-git-send-email-rnayak@codeaurora.org>
In-Reply-To: <1637650813-16654-1-git-send-email-rnayak@codeaurora.org>
References: <1637650813-16654-1-git-send-email-rnayak@codeaurora.org>
Precedence: bulk

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.
