[PATCH 0/8] sdhci: Move real work out of an atomic context

[Jeremie Samuel <jeremie.samuel.ext@parrot.com>]

Hi all,

Currently the sdhci driver does everything in the atomic context.
And what is worse, PIO transfers are made from the IRQ handler.

Some patches were already submitted to solve this issue. But there were
rejected because they involved new issues.

This set of patches is an evolution of an old patch from Anton Vorontsov.
I tried to fix all the problems involved by the patches. I tested it for
several time now with SD cards and SDIO.

So, this patch set reworks sdhci code to avoid atomic context,
almost completely.

Thanks,

Jeremie Samuel
