Subject: [PATCH V2] mmc: dw_mmc: exynos: Turn SDIO interrupts on
Date: Mon, 24 Mar 2014 09:53:57 +0530	[thread overview]
Message-ID: <1395635037-24081-1-git-send-email-yuvaraj.cd@samsung.com> (raw)

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 V1 of this patch is posted to LKML at
https://patchwork.kernel.org/patch/2429661/) by Doug Anderson.
