[PATCH 1/2] dt-bindings: Add pxa1928 clock binding

[Rob Herring]

This adds the clock binding documentation for the Marvell PXA1928 SOC.
The PXA1928 has 3 clock control blocks for different subsystems of the
chip.

+* 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>.
