clk: baikal-t1: Remove not-going-to-be-supported code for Baikal SoC

2026-03-24T00:17:59+00:00

As noticed in the discussion [1] the Baikal SoC and platforms are not going to be finalized, hence remove stale code.

dt-bindings: clk: Add Baikal-T1 CCU Dividers binding

2020-05-30T18:04:35+00:00

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.

dt-bindings: clk: Add Baikal-T1 CCU PLLs binding

2020-05-30T18:04:34+00:00

Baikal-T1 Clocks Control Unit is responsible for transformation of a signal coming from an external oscillator into clocks of various frequencies to propagate them then to the corresponding clocks consumers (either individual IP-blocks or clock domains). In order to create a set of high-frequency clocks the external signal is firstly handled by the embedded into CCU PLLs. So the corresponding dts-node is just a normal clock-provider node with standard set of properties. Note as being part of the Baikal-T1 System Controller its DT node is supposed to be a child the system controller node.
