-	  This driver supports TPS6594 voltage regulator chips.
+	  This driver supports TPS6594 series and TPS65224 voltage regulator chips.
 	  TPS6594 series of PMICs have 5 BUCKs and 4 LDOs
 	  voltage regulators.
 	  BUCKs 1,2,3,4 can be used in single phase or multiphase mode.
 	  Part number defines which single or multiphase mode is i used.
 	  It supports software based voltage control
 	  for different voltage domains.
+	  TPS65224 PMIC has 4 BUCKs and 3 LDOs. BUCK12 can be used in dual phase.
+	  All BUCKs and LDOs volatge can be controlled through software.
