+
+description: |
+  ARTPEC-9 clock controller is comprised of several CMU (Clock Management Unit)
+  units, generating clocks for different domains. Those CMU units are modeled
+  as separate device tree nodes, and might depend on each other.
+  The root clock in that root tree is an external clock: OSCCLK (25 MHz).
+  This external clock must be defined as a fixed-rate clock in dts.
+
+  CMU_CMU is a top-level CMU, where all base clocks are prepared using PLLs and
+  dividers, all other clocks of function blocks (other CMUs) are usually
+  derived from CMU_CMU.
+
+  Each clock is assigned an identifier and client nodes can use this identifier
+  to specify the clock which they consume. All clocks available for usage
+  in clock consumer nodes are defined as preprocessor macros in
+  'include/dt-bindings/clock/axis,artpec9-clk.h' header.
