Hi all,
These are the version 1 patches for enabling runtime power management for
mmc host driver stack.
Right now runtime pm in mmc driver stack can only care about the
power of SDIO card, not the host controller. Host controller also needs
runtime pm to save power.
MMC host can let the host device go into runtime suspended state when
there is no user request to deal, and wake up host device when there
comes one. MMC driver will manage the power of host controller like this
way.
patch1: implemented runtime pm for mmc host
patch2: implemented runtime pm for SDHCI host controller
patch3: Do not let mmc host clock gated when host is in runtime suspended
state.
Thanks
Chuanxiao
