1*c66ec88fSEmmanuel Vadot* Marvell PXA168 Clock Controller 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotThe PXA168 clock subsystem generates and supplies clock to various 4*c66ec88fSEmmanuel Vadotcontrollers within the PXA168 SoC. 5*c66ec88fSEmmanuel Vadot 6*c66ec88fSEmmanuel VadotRequired Properties: 7*c66ec88fSEmmanuel Vadot 8*c66ec88fSEmmanuel Vadot- compatible: should be one of the following. 9*c66ec88fSEmmanuel Vadot - "marvell,pxa168-clock" - controller compatible with PXA168 SoC. 10*c66ec88fSEmmanuel Vadot 11*c66ec88fSEmmanuel Vadot- reg: physical base address of the clock subsystem and length of memory mapped 12*c66ec88fSEmmanuel Vadot region. There are 3 places in SOC has clock control logic: 13*c66ec88fSEmmanuel Vadot "mpmu", "apmu", "apbc". So three reg spaces need to be defined. 14*c66ec88fSEmmanuel Vadot 15*c66ec88fSEmmanuel Vadot- #clock-cells: should be 1. 16*c66ec88fSEmmanuel Vadot- #reset-cells: should be 1. 17*c66ec88fSEmmanuel Vadot 18*c66ec88fSEmmanuel VadotEach clock is assigned an identifier and client nodes use this identifier 19*c66ec88fSEmmanuel Vadotto specify the clock which they consume. 20*c66ec88fSEmmanuel Vadot 21*c66ec88fSEmmanuel VadotAll these identifier could be found in <dt-bindings/clock/marvell,pxa168.h>. 22
