Hello all, This is version 3 of a patch series to introduce runtime pm in the imx serial driver. The idea is to get runtime pm to handle ipg and per clocks, idling the device when possible, configuring wakeups, and saving and restoring context when needed. A minor refactoring was needed to get things done. On top of it I am also adding pm_qos support in the driver too. Changelog: V3->V4: - Remove *dev from sport and reused sport->port.dev. - Rebased on top of tty-testing (initial 4 patches were already applied by greg) V3: https://lkml.org/lkml/2015/8/11/581 V2->V3: - error checking handling on clk_*enable functions - added a missing return - moved some of the code from the runtime pm patch to the pm qos patch, which were causing compilation issues. V2: http://marc.info/?l=linux-pm&m=143925695931624&w=2 V1->V2: - The difference now is that it is rebased on top of linux-next, given that some of the work done in v1 was already sent. V1: http://marc.info/?l=linux-pm&m=143914435605790&w=2 As always, comments are welcome.
