+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>.
