8 Over time, the intention is to merge features from the OMAP PM
9 interface into the Linux PM QoS code.
11 Drivers need to express PM parameters which:
15 - separate the drivers from the underlying PM parameter
16 implementation, whether it is the TI SRF or Linux PM QoS or Linux
19 - specify PM parameters in terms of fundamental units, such as
