Currently, there's already runtime PM support in the mmc core layer. But for the mmc storage card (SD card, mmc card, eMMC device and so on) to work with runtime PM, it also needs both block driver and host controller driver to implement the runtime PM support, which are not presented in current kernel. These patches implemented the runtime PM for both block driver and PCI interface SDHCI host controller driver. It also tried to fix some issues of current runtime PM implementation of mmc core layer.
