Subject: [PATCH] arm64: dts: qcom: qcm2290: Add TCSR download mode address
Date: Wed, 30 Jul 2025 18:52:30 +0530 [thread overview]
Message-ID: <20250730132230.247727-1-sumit.garg@kernel.org> (raw)
From: Sumit Garg <sumit.garg@oss.qualcomm.com>
Allow configuration of download mode via qcom_scm driver via specifying
download mode register address in the TCSR space. It is especially useful
for a clean watchdog reset without entry into download mode.
The problem remained un-noticed until now since error reporting for
missing download mode configuration feature was explicitly suppressed.
