Subject: [PATCH v3 11/18] arm64: dts: qcom: sm8450: Add Qualcomm ramoops minidump node
Date:   Wed, 3 May 2023 22:32:25 +0530

This enable dynamic reserve memory for Qualcomm ramoops device,
Which will used to save ramoops frontend data and this region
gets dumped on crash via Qualcomm's minidump infrastructure.
qcom_pstore_minidump is the associated driver for this node.
