Hi
Commit 03dbaa04a2e5 ("mmc: slot-gpio: Add support to enable irq wake on
cd_irq") enabled wakeup irrespective of the host controller's PM flags.
However, users also want to control it from sysfs power/wakeup attribute.
That means the driver needs to check the PM flags before enabling it in the
suspend callback. Patch 9 adds support for that in sdhci-pci, which is the
only driver presently using the MMC_CAP_CD_WAKE flag. Patches 1 - 7 tidy
up aspects of sdhci and sdhci-pci wakeup handling, and patch 8 adds a
helper function to make it easy for drivers.
Adrian Hunter (9):
mmc: sdhci-pci: Stop calling sdhci_enable_irq_wakeups()
mmc: sdhci-pci: Use device wakeup capability to determine MMC_PM_WAKE_SDIO_IRQ capability
mmc: sdhci: Stop exporting sdhci_enable_irq_wakeups()
mmc: sdhci: Handle failure of enable_irq_wake()
mmc: sdhci: Rework sdhci_enable_irq_wakeups()
mmc: sdhci: Do not unnecessarily enable wakeup for card detect interrupt
mmc: sdhci: Do not unnecessarily enable wakeup for SDIO card interrupt
mmc: slot-gpio: Add a function to enable/disable card detect IRQ wakeup
mmc: sdhci-pci: Respect PM flags when enabling card detect GPIO IRQ wakeup
