19 tree nodes, and might depend on each other. The root clock in that root tree
20 is an external clock: OSCCLK (26 MHz). This external clock must be defined
21 as a fixed-rate clock in dts.
23 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
28 in clock consumer nodes are defined as preprocessor macros in
29 'dt-bindings/clock/exynos7885.h' header.
