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.
