This domain contains the Coresight-ETM hardware block. As long as the ARM debug/perf code doesn't use resource management with runtime PM support, the D4 power domain must be kept powered to avoid a crash during resume from s2ram (dbg_cpu_pm_notify() calls reset_ctrl_regs() unconditionally, causing an undefined instruction oops).
