* Marvell PXA910 Clock ControllerThe PXA910 clock subsystem generates and supplies clock to variouscontrollers within the PXA910 SoC.Required Properties:- compatible: should be one of the following. - "marvell,pxa910-clock" - controller compatible with PXA910 SoC.- reg: physical base address of the clock subsystem and length of memory mapped region. There are 4 places in SOC has clock control logic: "mpmu", "apmu", "apbc", "apbcp". So four 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 identifierto specify the clock which they consume.All these identifier could be found in <dt-bindings/clock/marvell-pxa910.h>.
