18c2ecf20Sopenharmony_ci* Marvell PXA1928 Clock Controllers 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciThe PXA1928 clock subsystem generates and supplies clock to various 48c2ecf20Sopenharmony_cicontrollers within the PXA1928 SoC. The PXA1928 contains 3 clock controller 58c2ecf20Sopenharmony_ciblocks called APMU, MPMU, and APBC roughly corresponding to internal buses. 68c2ecf20Sopenharmony_ci 78c2ecf20Sopenharmony_ciRequired Properties: 88c2ecf20Sopenharmony_ci 98c2ecf20Sopenharmony_ci- compatible: should be one of the following. 108c2ecf20Sopenharmony_ci - "marvell,pxa1928-apmu" - APMU controller compatible 118c2ecf20Sopenharmony_ci - "marvell,pxa1928-mpmu" - MPMU controller compatible 128c2ecf20Sopenharmony_ci - "marvell,pxa1928-apbc" - APBC controller compatible 138c2ecf20Sopenharmony_ci- reg: physical base address of the clock controller and length of memory mapped 148c2ecf20Sopenharmony_ci region. 158c2ecf20Sopenharmony_ci- #clock-cells: should be 1. 168c2ecf20Sopenharmony_ci- #reset-cells: should be 1. 178c2ecf20Sopenharmony_ci 188c2ecf20Sopenharmony_ciEach clock is assigned an identifier and client nodes use the clock controller 198c2ecf20Sopenharmony_ciphandle and this identifier to specify the clock which they consume. 208c2ecf20Sopenharmony_ci 218c2ecf20Sopenharmony_ciAll these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>. 22
