Subject: [PATCH 2/3] arm64: dts: qcom: enable the download mode support
Date: Fri, 26 May 2023 16:36:52 +0530 [thread overview]
Message-ID: <20230526110653.27777-3-quic_viswanat@quicinc.com> (raw)
In-Reply-To: <20230526110653.27777-1-quic_viswanat@quicinc.com>
Like any other Qualcomm SoCs, IPQ8074 and IPQ6018 also supports the
download mode to collect the RAM dumps if system crashes, to perform
the post mortem analysis. Add support for the same.
