* Marvell PXA168 Clock Controller
The PXA168 clock subsystem generates and supplies clock to various
controllers within the PXA168 SoC.
Required Properties:
- compatible: should be one of the following.
- "marvell,pxa168-clock" - controller compatible with PXA168 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 identifier could be found in <dt-bindings/clock/marvell,pxa168.h>.
