When the CPAS probe fails (e.g. GDSC not enabled), downstream camera components leave stale entries in the v4l2 subdev list. The late_initcall cam_req_mgr_late_init then calls v4l2_device_register_subdev_nodes which iterates the corrupted list, hitting a NULL pointer deref and panicking. Gate the subdev node creation on CPAS probe success by checking cam_cpas_get_cpas_hw_version() before proceeding. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Attach the CPAS device to the camcc's TITAN_TOP_GDSC power domain via of_genpd_add_device() and enable pm_runtime. This is the first step toward enabling the GDSC — the domain is attached but not yet powered on (pm_runtime_resume_and_get deadlocks in deferred probe context). Direct ioremap of the GDSC register (0xad0b134) is blocked by TrustZone on this platform, so the genpd framework is the only viable path.
