+
+description: |
+  Clocks Control Unit is the core of Baikal-T1 SoC System Controller
+  responsible for the chip subsystems clocking and resetting. The CCU is
+  connected with an external fixed rate oscillator, which signal is transformed
+  into clocks of various frequencies and then propagated to either individual
+  IP-blocks or to groups of blocks (clock domains). The transformation is done
+  by means of an embedded into CCU PLLs and gateable/non-gateable dividers. The
+  later ones are described in this binding. Each clock domain can be also
+  individually reset by using the domain clocks divider configuration
+  registers. Baikal-T1 CCU is logically divided into the next components:
+  1) External oscillator (normally XTAL's 25 MHz crystal oscillator, but
+     in general can provide any frequency supported by the CCU PLLs).
+  2) PLLs clocks generators (PLLs).
+  3) AXI-bus clock dividers (AXI) - described in this binding file.
+  4) System devices reference clock dividers (SYS) - described in this binding
+     file.
+  which are connected with each other as shown on the next figure:
+
+          +---------------+
+          | Baikal-T1 CCU |
+          |   +----+------|- MIPS P5600 cores
+          | +-|PLLs|------|- DDR controller
+          | | +----+      |

+  |XTAL|--|-+  |  | +---+-|

+          | |  +----+---+-|- APB-bus
+          | +-------|SYS|-|- Low-speed Devices
+          |         +---+-|- High-speed Devices
+          +---------------+
+
+  Each sub-block is represented as a separate DT node and has an individual
+  driver to be bound with.
+
+  In order to create signals of wide range frequencies the external oscillator
+  output is primarily connected to a set of CCU PLLs. Some of PLLs CLKOUT are
+  then passed over CCU dividers to create signals required for the target clock
+  domain (like AXI-bus or System Device consumers). The dividers have the
+  following structure:
+
+          +--------------+
+  CLKIN --|->+----+ 1|\  |
+  SETCLK--|--|/DIV|->| | |
+  CLKDIV--|--|    |  | |-|->CLKLOUT
+  LOCK----|--+----+  | | |
+          |          |/  |
+          |           |  |
+  EN------|-----------+  |
+  RST-----|--------------|->RSTOUT
+          +--------------+
+
+  where CLKIN is the reference clock coming either from CCU PLLs or from an
+  external clock oscillator, SETCLK - a command to update the output clock in
+  accordance with a set divider, CLKDIV - clocks divider, LOCK - a signal of
+  the output clock stabilization, EN - enable/disable the divider block,
+  RST/RSTOUT - reset clocks domain signal. Depending on the consumer IP-core
+  peculiarities the dividers may lack of some functionality depicted on the
+  figure above (like EN, CLKDIV/LOCK/SETCLK). In this case the corresponding
+  clock provider just doesn't expose either switching functions, or the rate
+  configuration, or both of them.
+
+  The clock dividers, which output clock is then consumed by the SoC individual
+  devices, are united into a single clocks provider called System Devices CCU.
+  Similarly the dividers with output clocks utilized as AXI-bus reference clocks
+  are called AXI-bus CCU. Both of them use the common clock bindings with no
+  custom properties. The list of exported clocks and reset signals can be found
+  in the files: 'include/dt-bindings/clock/bt1-ccu.h' and
+  'include/dt-bindings/reset/bt1-ccu.h'. Since System Devices and AXI-bus CCU
+  are a part of the Baikal-T1 SoC System Controller their DT nodes are supposed
+  to be a children of later one.

+
+  Each CCU sub-block is represented as a separate dts-node and has an
+  individual driver to be bound with.
+
+  In order to create signals of wide range frequencies the external oscillator
+  output is primarily connected to a set of CCU PLLs. There are five PLLs
+  to create a clock for the MIPS P5600 cores, the 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 core
+  with an interface wrapper (so called safe PLL' clocks switcher) to simplify
+  the PLL configuration procedure. The PLLs work as depicted on the next
+  diagram:
+
+      +--------------------------+
+      |                          |

+  BYPASS--------------------------------------+
+  BWADJ--->
+
+  where Rclk is the reference clock coming  from XTAL, NR - reference clock
+  divider, NF - PLL clock multiplier, OD - VCO output clock divider, CLKOUT -
+  output clock, BWADJ is the PLL bandwidth adjustment parameter. At this moment
+  the binding supports the PLL dividers configuration in accordance with a
+  requested rate, while bypassing and bandwidth adjustment settings can be
+  added in future if it gets to be necessary.
+
+  The PLLs CLKOUT is then either directly connected with the corresponding
+  clocks consumer (like P5600 cores or DDR controller) or passed over a CCU
+  divider to create a signal required for the clock domain.
+
+  The CCU PLL dts-node uses the common clock bindings with no custom
+  parameters. The list of exported clocks can be found in
+  'include/dt-bindings/clock/bt1-ccu.h'. Since CCU PLL is a part of the
+  Baikal-T1 SoC System Controller its DT node is supposed to be a child of

+	  between AXI-bus and system devices coming from CCU PLLs of Baikal-T1
