What about: - register the (generic ?) runtime PM handlers to mmc_host_class - call the runtime pm get/put API on host->class_dev (in mmc_start_request/mmc_request_done) - use runtime PM autosuspend for taking care of the required delay The host controller will get the idle notification directly to its runtime PM handlers.
