X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1b7fc8a281cae9e3176584558a4ac551ce0f777d;p=thirdparty%2Flinux.git

arm64: dts: qcom: qcs615: disable the CTI device of the camera block

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.
