+description: |
+  The PXA1908 clock subsystem generates and supplies clock to various
+  controllers within the PXA1908 SoC. The PXA1908 contains numerous clock
+  controller blocks, with the ones currently supported being APBC, APBCP, MPMU
+  and APMU roughly corresponding to internal buses.
+
+  All these clock identifiers could be found in <include/dt-bindings/marvell,pxa1908.h>.
+

+  compatible:
+    enum:
+      - marvell,pxa1908-apbc
