     13description: |
     14  FSD clock controller consist of several clock management unit
     15  (CMU), which generates clocks for various inteernal SoC blocks.
     16  The root clock comes from external OSC clock (24 MHz).
     17
     18  All available clocks are defined as preprocessor macros in
     19  'dt-bindings/clock/fsd-clk.h' header.
