Subject: [PATCH v2] arm64: dts: qcom: qcs615: disable the CTI device of the camera block
Date: Wed, 11 Jun 2025 11:00:03 +0800 [thread overview]
Message-ID: <20250611030003.3801-1-jie.gan@oss.qualcomm.com> (raw)
Disable the CTI device of the camera block to prevent potential NoC errors
during AMBA bus device matching.
The clocks for the Qualcomm Debug Subsystem (QDSS) are managed by aoss_qmp
through a mailbox. However, the camera block resides outside the AP domain,
meaning its QDSS clock cannot be controlled via aoss_qmp.
Fixes: bf469630552a ("arm64: dts: qcom: qcs615: Add coresight nodes")
