Hi Jaehoon and Ulf, This a patchset going to support runtime PM for dw_mmc. Basically it is a prototype design with some redundant code there. But I think it's okay to send it out for sure I am not heading in the wrong direction. Still something more need to support: (1) Support switching sd detect to gpio irq wakeup when calling runtime PM. (2) Then we could disable/enable biu_clk and add off/on genpd for runtime PM (3) remove dw_mci_suspend/resume and migrate dw_mci variant driver to use dw_mci_runtime_suspend/resume(Although I am not so sure) Shawn Lin (2): mmc: dw_mmc: add runtime PM callback mmc: dw_mmc-rockchip: add runtime PM support drivers/mmc/host/dw_mmc-rockchip.c | 57 ++++++++++++++++++++++++++++++++++-- drivers/mmc/host/dw_mmc.c | 60 ++++++++++++++++++++++++++++++++++++-- drivers/mmc/host/dw_mmc.h | 4 ++- 3 files changed, 115 insertions(+), 6 deletions(-) -- 2.3.7 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
