+* Marvell PXA1928 Clock Controllers
+
+The PXA1928 clock subsystem generates and supplies clock to various
+controllers within the PXA1928 SoC. The PXA1928 contains 3 clock controller
+blocks called APMU, MPMU, and APBC roughly corresponding to internal buses.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "marvell,pxa1928-apmu" - APMU controller compatible
+ - "marvell,pxa1928-mpmu" - MPMU controller compatible
+ - "marvell,pxa1928-apbc" - APBC controller compatible
+- reg: physical base address of the clock controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes use the clock controller
+phandle and this identifier to specify the clock which they consume.
+
+All these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>.
