What about this now:
+Example 5: Multiple OPP tables
+
+/ {
+       cpus {
+               cpu at 0 {
+                       compatible = "arm,cortex-a7";
+                       ...
+
+                       opp-supply = <&cpu_supply>
+                       operating-points-v2 = <&cpu0_opp_table_slow>, <&cpu0_opp_table_fast>;
+               };
+       };
+
+       cpu0_opp_table_slow: opp_table_slow {
+               compatible = "operating-points-v2";
+               opp-name = "slow";
+               opp-shared;
+
+               opp00 {
+                       opp-hz = <600000000>;
+                       ...
+               };
+
+               opp01 {
+                       opp-hz = <800000000>;
+                       ...
+               };
+       };
+
+       cpu0_opp_table_fast: opp_table_fast {
+               compatible = "operating-points-v2";
+               opp-name = "fast";
+               opp-shared;
+
+               opp10 {
+                       opp-hz = <1000000000>;
+                       ...
+               };
+
+               opp11 {
+                       opp-hz = <1100000000>;
+                       ...
+               };
+       };
+};

May I carry your Ack or you want to give it again?
