After being gained by the CCU PLLs the signals must be transformed to be suitable for the clock-consumers. This is done by a set of dividers embedded into the CCU. A first block of dividers is used to create reference clocks for AXI-bus of high-speed peripheral IP-cores of the chip. The second block dividers alter the PLLs output signals to be then consumed by SoC peripheral devices. Both block DT nodes are ordinary clock-providers with standard set of properties supported. But in addition to that each clock provider can be used to reset the corresponding clock domain. This makes the AXI-bus and System Devices CCU DT nodes to be also reset-providers.
