![]() In some environments it is to prefer to postpone the resume of the card device until runtime_resume is being carried out, since it will mean a signficant decrease of the total system resume time. The reason of the decreased resume time is simply because of the actual re-initalization of the card, which typically takes hundreds of milliseconds, is performed outside the resume sequence and wont thus affect it. For removable card, the detect work tries to re-detect the card to make sure it is still present, as a part of that sequence the card will also be runtime_resumed and thus also fully resumed. For a non-removable card, typically a mmc blk request will trigger a runtime_resume and thus fully resume the card. This also means the first request will likely suffer from an inital latency since the re-initialization of the card needs to be performed.
