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