16   ExynosAuto v920 clock controller is comprised of several CMU units, generating
17   clocks for different domains. Those CMU units are modeled as separate device
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
29   'include/dt-bindings/clock/samsung,exynosautov920.h' header.
