With runtime power save feature enabled, Headphone hotplug event will not be detected while controller/codec in D3. HDA has feature WAKEEN to let codec wake up system if controller is in D3 or system in S3.(HDA Spec 4.5.9.2/3). Codec can send out INT or wake up controller depending on whether CIE or GIE enabled.(Figure 4, Interupt structure). The controller must be in RESET mode after enter runtime-suspend, otherwise it will not be waken up even if codec send out wake-up event. And STATESTS will be cleared after controller brought out of RESET mode. This patch only enable WAKEEN for runtime-suspend(Controller D3) mode, not for system S3 mode. with tool "evtest", Headphone hotplug events could be cought and reported successfully.
