+Binding for ST's CPUFreq driver
+===============================
+
+Frequency Scaling only
+----------------------
+
+Located in CPU's node:
+
+- operating-points : [See: ../power/opp.txt]
+
+Example [safe]
+--------------
+
+cpus {
+ cpu@0 {
+ /* kHz uV */
+ operating-points = <1500000 0
+ 1200000 0
+ 800000 0
+ 500000 0>;
+ };
+};
+
+Dynamic Voltage and Frequency Scaling (DVFS)
+--------------------------------------------
+
+Located in CPU's node:
+
+- operating-points-v2-sti : [See ../power/opp-st.txt]
+
+Example [unsafe]
+----------------
+
+cpus {
+ cpu@0 {
+ operating-points-v2 = <[OPP list phandle]>;
+ };
+};
+
+For an example of an OPP list, see ../power/opp-st.txt.
