Subject: [PATCH v3 2/5] mmc: sdhci-esdhc: Add SDHCI_QUIRK_32BIT_DMA_ADDR
Date: Tue, 30 May 2017 11:14:08 +0200 [thread overview]
Message-ID: <1496135651-90007-2-git-send-email-benoit@wsystem.com> (raw)
In-Reply-To: <1496135651-90007-1-git-send-email-benoit@wsystem.com>
The eSDHC can only DMA from 32-bit-aligned addresses.
This fixes the following test cases of mmc_test:
11: Badly aligned write
12: Badly aligned read
13: Badly aligned multi-block write
14: Badly aligned multi-block read
Signed-off-by: Benoît Thébaudeau <benoit@wsystem.com>
