Subject: [PATCH V1 1/4] dt-bindings: sram: qcom,imem: Add Boot Stat region within IMEM
Date: Tue, 21 Mar 2023 19:21:48 +0530	[thread overview]
Message-ID: <1589f33deda07cb9f9e6c3c26bce6e02e53c168e.1679403696.git.quic_schowdhu@quicinc.com> (raw)
In-Reply-To: <cover.1679403696.git.quic_schowdhu@quicinc.com>

All Qualcomm bootloaders log useful timestamp information related
to bootloader stats in the IMEM region. Add the child node within
IMEM for the boot stat region containing register address and
compatible string.
