  13 description: |
  14   The clock enumerators are defined in <dt-bindings/clock/qcom,rpmcc.h> and
  15   come in pairs:: FOO_CLK followed by FOO_A_CLK. The latter clock is
  16   an "active" clock, which means that the consumer only care that the clock is
  17   available when the apps CPU subsystem is active, i.e. not suspended or in
  18   deep idle. If it is important that the clock keeps running during system
  19   suspend, you need to specify the non-active clock, the one not containing
  20   *_A_* in the enumerator name.
