Cover letter [PATCH v2 0/3]mmc: enable runtime PM support for mmc storage card
Hi,
These are the version 2 patches to enable the runtime PM support for mmc storage cards.
Ohad Ben-Cohen has gave very good comments on the version 1 patches. And now the version 2 patches tries to fix the problems identified by Ohad.
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.
