From 3cf38833c7fc72b4f4757fc5d0b4cd43ac192e55 Mon Sep 17 00:00:00 2001 From: Jerry Huang Date: Fri, 23 Nov 2012 17:25:03 +0800 Subject: [PATCH] mmc: sdhci-of-esdhc: support commands with busy response expecting TC The IP versions older than 2.3 didn't support commands with busy response which expect the TC bit set. But after the VVN2.3, eSDHC IP has supported it.
