  The MMP2 clock subsystem generates and supplies clock to various

  controllers within the MMP2 SoC.

  Each clock is assigned an identifier and client nodes use this identifier

  to specify the clock which they consume.

  All these identifiers could be found in <dt-bindings/clock/marvell,mmp2.h>.

* Marvell MMP2 Clock Controller

The MMP2 clock subsystem generates and supplies clock to various

controllers within the MMP2 SoC.

Required Properties:

- compatible: should be one of the following.

  - "marvell,mmp2-clock" - controller compatible with MMP2 SoC.

- reg: physical base address of the clock subsystem and length of memory mapped

  region. There are 3 places in SOC has clock control logic:

  "mpmu", "apmu", "apbc". So three reg spaces need to be defined.

- #clock-cells: should be 1.

- #reset-cells: should be 1.

Each clock is assigned an identifier and client nodes use this identifier

to specify the clock which they consume.

All these identifiers could be found in <dt-bindings/clock/marvell,mmp2.h>.
