16 ExynosAuto v920 clock controller is comprised of several CMU units, generating
18 tree nodes, and might depend on each other. Root clocks in that clock tree are
20 The external OSCCLK must be defined as fixed-rate clock in dts.
22 CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
26 Each clock is assigned an identifier and client nodes can use this identifier
27 to specify the clock which they consume. All clocks available for usage
28 in clock consumer nodes are defined as preprocessor macros in
29 'include/dt-bindings/clock/samsung,exynosautov920.h' header.
