Hi guys, I have recently added PM support for my driver but I don't have the behavior I was expecting. I am wondering if I didn't do something wrong. I have implemented runtime_suspend in a very simple way, I call sdhci_runtime_suspend_host() and I disable the clocks. It works pretty well with the eMMC which is non removable but with a SD card... If I have my SD card present on boot time, it is detected but insertion/removal is not detected. Having a look to sdhci_runtime_suspend_host() internal, all the interruptions are disabled expecting the card interrupt if it has been set earlier. >From my understanding, it means that if there is no activity on sdhci, we will go to suspend and then we could wake up only on a software event (or a sdio interrupt). How to manage card insertion/removal in this case? My problem is so huge, I have probably missed something... Moreover, to avoid system PM, I have used pm_runtime_force_suspend but I could not wake up on card insertion/removal too. Do I have to use system PM if I want to manage this case? Thanks for your advices.
