Rafael, Any comments here? > It's getting enabled by drivers/pci/pci-driver.c:local_pci_probe(), > before the sdhci-pci probe function runs. local_pci_probe() does: > > /* Unbound PCI devices are always set to disabled and suspended. > * During probe, the device is set to enabled and active and the > * usage count is incremented.

Sounds like it is a change post 2.6.37. So we need to replace the current sdhci runtime_pm initialization by what is in this comments. > > Maybe Rafael can advice on this. > > The controller advertises the ability to generate PME wakeups from D3 > in its PCI capabilities; perhaps we just aren't programming it properly. > I don't see anything in your patch that would set SDHCI wakeup bits or > unmask card insertion/removal IRQs -- maybe that could be it? My understanding is the pci driver is not supposed to do any set_power_state/pci_save_state/wake_enable. Everything is supposed to be generically handle by pci frameworks's runtime_pm impl. Need confirmation from Rafael.
