The next change will remove the code from the dw_mmc-exynos that added
the DW_MCI_QUIRK_NO_WRITE_PROTECT. Keep existing functionality of
having no write protect pin on smdk5250 by adding the disable-wp
property.

Changes in v3:
- New for this version of the patch
The "disable-wp" property is used to specify that a given SD card slot
doesn't have a concept of write protect. This eliminates the need for
special case code for SD slots that should never be write protected
(like a micro SD slot or a dev board).
The dw_mmc driver is special in needing to specif

On some SoCs (like exynos5250) you need to use an external GPIO for
write protect. Add support for wp-gpios to the core dw_mmc driver
since it could be useful across multiple SoCs.
With this change I am able to make use of the write protect for the
external SD slot on exynos5250-snow.
Signed-off
The exynos code claimed the write protect with devm_gpio_request() but
never did anything with it. That meant that anyone using a write
protect GPIO would effectively be write protected all the time.
The handling for wp-gpios belongs in the main dw_mmc driver and has
been moved there.

Hi Chris:
May I ask that whether drivers/mmc has a plan to support SDIO 4.0? If
does, what is the schedule?
Thank you

Hi Maya,
Thank you a lot for working idle time BKOPS.
I tested with this patch. It's working fine.(Suspend/resume is also working
well.)
Test controller is sdhci controller.
When i tested the performance with iozone, i didn't find that performance is
decreased.
Well, as Chris is mentioned, do
