1*c66ec88fSEmmanuel Vadot* Marvell PXA1928 Clock Controllers 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotThe PXA1928 clock subsystem generates and supplies clock to various 4*c66ec88fSEmmanuel Vadotcontrollers within the PXA1928 SoC. The PXA1928 contains 3 clock controller 5*c66ec88fSEmmanuel Vadotblocks called APMU, MPMU, and APBC roughly corresponding to internal buses. 6*c66ec88fSEmmanuel Vadot 7*c66ec88fSEmmanuel VadotRequired Properties: 8*c66ec88fSEmmanuel Vadot 9*c66ec88fSEmmanuel Vadot- compatible: should be one of the following. 10*c66ec88fSEmmanuel Vadot - "marvell,pxa1928-apmu" - APMU controller compatible 11*c66ec88fSEmmanuel Vadot - "marvell,pxa1928-mpmu" - MPMU controller compatible 12*c66ec88fSEmmanuel Vadot - "marvell,pxa1928-apbc" - APBC controller compatible 13*c66ec88fSEmmanuel Vadot- reg: physical base address of the clock controller and length of memory mapped 14*c66ec88fSEmmanuel Vadot region. 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 the clock controller 19*c66ec88fSEmmanuel Vadotphandle and this identifier to specify the clock which they consume. 20*c66ec88fSEmmanuel Vadot 21*c66ec88fSEmmanuel VadotAll these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>. 22
