Subject: [PATCH v2 00/11] mmc: core: PM fixes/improvements for SDIO IRQs 

Changes in v2:
	- Added reviewed/tested-by tags.
	- Updated some changelogs.
	- Renamed sdio_irq_enabled() to sdio_irq_claimed().
	- Don't set sdio_irq_pending when resuming SDIO card, but just queue the
	work.

The power management support for SDIO cards have slowly been improved, but
there are still quite some serious problems, especially when dealing with the
so called SDIO IRQs during system suspend/resume.

This series makes some additional improvements to this code in the mmc core,
but also includes some needed adaptations for the sdhci, the dw_mmc and the
mtk-sd host drivers.

The series is also available at:
git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git sdio_irq_suspend_next_v2

Kind regards
Uffe
