Please find sdhci runtime_pm implementation. It uses clock gating fw as a tip to know when our chip is idle. It implements wake up from card insertion/removal. This is RFC, please dont merge yet. I really would like to have deep review from PCI linux-pm guys. Opens are: 1/ Not sure if the pci configs in the driver in rpm_suspend/resume flow are not duplicate from what the core is doing. 2/ Wakeup from D3hot: I cannot find any driver that is implementing it in current upstream, I'm not sure if I'm doing it the good way. We have the exact same issue for our not yet upstreamable usb-otg driver. Not sure if this cannot be implemented generically in core. version 1: was RFC and untested, version 2: has been tested on intel medfield platform. version 3: RFC, untested. - Change runtime_pm initialization to match latest PCI framework scheme - Added wake-up support Pierre Tardy (2): mmc: sdhci: use ios->clock to know when sdhci is idle mmc: sdhci: handle wake-up from runtime_pm Yunpeng Gao (1): mmc: sdhci-pci: Enable runtime PM support drivers/mmc/host/sdhci-pci.c | 117 +++++++++++++++++++++++++++++++++++++++++- drivers/mmc/host/sdhci.c | 88 +++++++++++++++++++++++++++++++ drivers/mmc/host/sdhci.h | 5 ++ include/linux/mmc/sdhci.h | 3 + scripts/checkpatch.pl | 6 +- 5 files changed, 215 insertions(+), 4 deletions(-) _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
