Subject: [PATCH 4/4 V2] mmc: esdhc: Add broken timeout quirk for p4/p5 board
Date: Wed, 17 Jul 2013 18:11:31 +0800	[thread overview]
Message-ID: <1374055891-20703-3-git-send-email-Haijun.Zhang@freescale.com> (raw)
In-Reply-To: <1374055891-20703-1-git-send-email-Haijun.Zhang@freescale.com>

Sometimes command can't be completed within the time give
in eSDHC_SYSCTL[DTOCV]. So just give the max value 0x14 to
avoid this issue.

Signed-off-by: Haijun Zhang <haijun.zhang@freescale.com>

changes for v2:
	- Rebuild patch of eSDHC host need long time to generate
	 command interrupt
