| 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. |
