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.
So far the series has only been compile tested, so definitely need some help in
testing this on HW, which of course would be greatly appreciated.
The series is also available at:
git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git sdio_irq_suspend_next
Kind regards
