title: Marvell PXA1908 Clock Controllers

maintainers:

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>.
