162306a36Sopenharmony_ci* Marvell PXA1928 Clock Controllers 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciThe PXA1928 clock subsystem generates and supplies clock to various 462306a36Sopenharmony_cicontrollers within the PXA1928 SoC. The PXA1928 contains 3 clock controller 562306a36Sopenharmony_ciblocks called APMU, MPMU, and APBC roughly corresponding to internal buses. 662306a36Sopenharmony_ci 762306a36Sopenharmony_ciRequired Properties: 862306a36Sopenharmony_ci 962306a36Sopenharmony_ci- compatible: should be one of the following. 1062306a36Sopenharmony_ci - "marvell,pxa1928-apmu" - APMU controller compatible 1162306a36Sopenharmony_ci - "marvell,pxa1928-mpmu" - MPMU controller compatible 1262306a36Sopenharmony_ci - "marvell,pxa1928-apbc" - APBC controller compatible 1362306a36Sopenharmony_ci- reg: physical base address of the clock controller and length of memory mapped 1462306a36Sopenharmony_ci region. 1562306a36Sopenharmony_ci- #clock-cells: should be 1. 1662306a36Sopenharmony_ci- #reset-cells: should be 1. 1762306a36Sopenharmony_ci 1862306a36Sopenharmony_ciEach clock is assigned an identifier and client nodes use the clock controller 1962306a36Sopenharmony_ciphandle and this identifier to specify the clock which they consume. 2062306a36Sopenharmony_ci 2162306a36Sopenharmony_ciAll these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>. 22
