2022-10-01	dt-bindings: clk: baikal-t1: Add DDR/PCIe reset IDs	Serge Semin	1	-0/+9
	Aside with a set of the trigger-like resets Baikal-T1 CCU provides additional directly controlled reset signals for the DDR and PCIe controllers. As a preparation before adding these resets support to the kernel let's extent the Baikal-T1 CCU IDs list with the new IDs, which will be used to access the corresponding reset controls.

2020-05-30	dt-bindings: clk: Add Baikal-T1 CCU Dividers binding	Serge Semin	1	-0/+25
	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.
