   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.
