+	  Enable reference count tracking for DPLL devices and pins.
+	  This helps debugging reference leaks and use-after-free bugs
+	  by recording stack traces for each get/put operation.
+
+	  The tracking information is exposed via debugfs at:
+	    /sys/kernel/debug/ref_tracker/dpll_device_*
+	    /sys/kernel/debug/ref_tracker/dpll_pin_*
+
+	  If unsure, say N.
