Subject: [PATCH 1/5] arm64: dts: qcom: Add base SM4450 DTSI
Date:   Wed, 19 Jul 2023 18:01:31 +0800
Message-ID: <20230719100135.21325-2-quic_tengfan@quicinc.com>
In-Reply-To: <20230719100135.21325-1-quic_tengfan@quicinc.com>

Precedence: bulk

This add based DTSI for SM4450 SoC and includes base description of
CPUs and interrupt-controller which helps to boot to shell with
console on boards with this SoC.
