+          This driver is for a SoC level watchdog that exists on some
+          Freescale PowerPC processors. So far this driver supports:
+          - MPC8xx watchdogs
+          - MPC83xx watchdogs
+          - MPC86xx watchdogs
+
+          For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.
