From 1e3600919eddb4746c851f47cea319732f9ae894 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Thu, 6 Mar 2014 18:45:33 +0800 Subject: ENGR00302227-7 dts: imx6sx-17x17-arm2: do not use sw polling for card detect The SW polling for card detect will keep sending command repeatly at backgroud which will consume CPU MIPS and aslo affects the normal SD debug when enable CONFIG_MMC_DEBUG. Just as the board design, we simply treat it as no card detect support.
