 13description: |
 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.
