19 tree nodes, and might depend on each other. Root clocks in that clock tree are
20 two external clocks:: OSCCLK (26 MHz) and RTCCLK (32768 Hz). Those external
21 clocks must be defined as fixed-rate clocks 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/exynos850.h' header.
