+title: Samsung Exynos850 SoC clock controller

+
+description: |
+ Exynos850 clock controller is comprised of several CMU units, generating
+ clocks for different domains. Those CMU units are modeled as separate device
+ tree nodes, and might depend on each other. Root clocks in that clock tree are
+ two external clocks:: OSCCLK (26 MHz) and RTCCLK (32768 Hz). Those external
+ clocks must be defined as fixed-rate clocks in dts.
+
+ CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
+
+ 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
+ 'dt-bindings/clock/exynos850.h' header.
