+* Marvell MMP2 Clock Controller
+
+The MMP2 clock subsystem generates and supplies clock to various
+controllers within the MMP2 SoC.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "marvell,mmp2-clock" - controller compatible with MMP2 SoC.
+
+- reg: physical base address of the clock subsystem and length of memory mapped
+ region. There are 3 places in SOC has clock control logic:
+ "mpmu", "apmu", "apbc". So three reg spaces need to be defined.
+
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.
+
+All these identifier could be found in <dt-bindings/clock/marvell-mmp2.h>.
