Nearly each Baikal-T1 IP-core is supposed to have a clock source of particular frequency. But since there are greater than five IP-blocks embedded into the SoC, the CCU PLLs can't fulfill all the needs. Baikal-T1 CCU provides a set of fixed and configurable clock dividers in order to generate a necessary signal for each chip sub-block. This driver creates the of-based hardware clocks for each divider available in Baikal-T1 CCU. The same way as for PLLs we split the functionality up into the clocks operations (gate, ungate, set rate, etc) and hardware clocks declaration/registration procedures. In accordance with the CCU documentation all its dividers are distributed into two CCU sub-blocks: AXI-bus and system devices reference clocks. The former sub-block is used to supply the clocks for AXI-bus interfaces (AXI clock domains) and the later one provides the SoC IP-cores reference clocks. Each sub-block is represented by a dedicated DT node, so they have different compatible strings to distinguish one from another. For some reason CCU provides the dividers of different types. Some dividers can be gateable some can't, some are fixed while the others are variable, some have special divider' limitations, some've got a non-standard register layout and so on. In order to cover all of these cases the hardware clocks driver is designed with an info-descriptor pattern. So there are special static descriptors declared for the dividers of each type with additional flags describing the block peculiarity. These descriptors are then used to create hardware clocks with proper operations. Some CCU dividers provide a way to reset a domain they generate a clock for. So the CCU AXI-bus and CCU system devices clock drivers also perform the reset controller registration. Signed-off-by:

Baikal-T1 is supposed to be supplied with a high-frequency external oscillator. But in order to create signals suitable for each IP-block embedded into the SoC the oscillator output is primarily connected to a set of CCU PLLs. There are five of them to create clocks for the MIPS P5600 cores, an embedded DDR controller, SATA, Ethernet and PCIe domains. The last three domains though named by the biggest system interfaces in fact include nearly all of the rest SoC peripherals. Each of the PLLs is based on True Circuits TSMC CLN28HPM IP-core with an interface wrapper (so called safe PLL' clocks switcher) to simplify the PLL configuration procedure. This driver creates the of-based hardware clocks to use them then in the corresponding subsystems. In order to simplify the driver code we split the functionality up into the PLLs clocks operations and hardware clocks declaration/registration procedures. Even though the PLLs are based on the same IP-core, they may have some differences. In particular, some CCU PLLs support the output clock change without gating them (like CPU or PCIe PLLs), while the others don't, some CCU PLLs are critical and aren't supposed to be gated. In order to cover all of these cases the hardware clocks driver is designed with an info-descriptor pattern. So there are special static descriptors declared for each PLL, which is then used to create a hardware clock with proper operations. Additionally debugfs-files are provided for each PLL' field to make sure the implemented rate-PLLs-dividers calculation algorithm is correct. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

The PLL of X1830 Soc from Ingenic has been greatly changed, the bypass control is placed in another register, so now two registers may needed to control the PLL. To this end, a new "bypass_reg" was introduced. In addition, when calculating rate, the PLL of X1830 introduced an extra 2x multiplier, so a new "rate_multiplier" was introduced.
