162306a36Sopenharmony_ci* Marvell PXA910 Clock Controller 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciThe PXA910 clock subsystem generates and supplies clock to various 462306a36Sopenharmony_cicontrollers within the PXA910 SoC. 562306a36Sopenharmony_ci 662306a36Sopenharmony_ciRequired Properties: 762306a36Sopenharmony_ci 862306a36Sopenharmony_ci- compatible: should be one of the following. 962306a36Sopenharmony_ci - "marvell,pxa910-clock" - controller compatible with PXA910 SoC. 1062306a36Sopenharmony_ci 1162306a36Sopenharmony_ci- reg: physical base address of the clock subsystem and length of memory mapped 1262306a36Sopenharmony_ci region. There are 4 places in SOC has clock control logic: 1362306a36Sopenharmony_ci "mpmu", "apmu", "apbc", "apbcp". So four reg spaces need to be defined. 1462306a36Sopenharmony_ci 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 this identifier 1962306a36Sopenharmony_cito specify the clock which they consume. 2062306a36Sopenharmony_ci 2162306a36Sopenharmony_ciAll these identifier could be found in <dt-bindings/clock/marvell-pxa910.h>. 22
