Subject[PATCH] mmc: dw_mmc: exynos: Turn SDIO interrupts on
Date
The mmc part in exynos supports SDIO interrupts and they work fine, so
turn the capability on. With this I see download speeds increase
about 10x. This is a port of a change present in the Chrome OS tree
that can be found at <https://gerrit.chromium.org/gerrit/#/c/26729/>.
