0013 description: |
0014   The clock enumerators are defined in <dt-bindings/clock/qcom,rpmcc.h> and
0015   come in pairs:: FOO_CLK followed by FOO_A_CLK. The latter clock is
0016   an "active" clock, which means that the consumer only care that the clock is
0017   available when the apps CPU subsystem is active, i.e. not suspended or in
0018   deep idle. If it is important that the clock keeps running during system
0019   suspend, you need to specify the non-active clock, the one not containing
0020   *_A_* in the enumerator name.
