description: |
Exynos Auto v9 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/XTCXO (26 MHz) and RTCCLK/XrtcXTI (32768 Hz).
The external OSCCLK must be defined as fixed-rate clock in dts.
CMU_TOP 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_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
'include/dt-bindings/clock/samsung,exynosautov9.h' header.
